Facilitators and barriers to the implementation of the biobehavioral survey among incarcerated individuals and correctional personnel in Mozambique, 2021- a descriptive study.

Mozambique implemented in 2021 a formative assessment in 22 prisons to identify the operational and logistical needs for the second round of the Biobehavioral Survey (BBS). Barriers and facilitators that could be anticipated in conducting BBS in prisons, in preparation for implementation, was evaluated using semi-structured questionnaires administered to key informants (directors and other kind of managers staff). The data were cleaned and analyzed using Microsoft Excel, and the categorical variables were summarized by means of simple frequencies and percentages. In most prisons the current prison capacity far exceeds the theoretical capacity, 40.9% have a theoretical capacity of ≥ 50 inmates, 81.8% have inmates who exceed their theoretical capacity. In the country half of the prisons receive only male inmates, and only one female, 54.5% of the prisons visited have inmates under 18 years of age, 72.7% of the prisons had a private space available for the survey, the penitentiary establishments have the physical space for study; ensuring the safety of staff within the facilities; involvement of correctional officers and a clinical focal point. However, barriers such as time management due to prison opening hours, prison laws, restrictions, or permits for research may change without notice due to security, lockdowns, riots, or other situations that may hinder the implementation of research. The implementation of successive and regular rounds of BBS in different environments, contexts and populations constitute opportunities for generating information and indicators not always captured by programmatic data and not only as an opportunity for offering and making healthcare available in prison environments that in a routine context, but these populations normally have also not had equal opportunities. Currently, little is known about the implementation of a BBS in a correctional environment and only a few barriers can be anticipated, for Mozambique's context, these challenges and obstacles can be overcome through clear communication and collaboration with officials at all levels.

Patterns of inconsistent condom use and risky sexual behaviors among female sex workers in Mozambique.

BACKGROUND: Female sex workers (FSWs) in Mozambique face significant health risks, including high HIV prevalence, combination of factors, including inconsistent condom use, engagement in risky sexual behaviors, and various socio-ecological determinants of health. Understanding the determinants of these practices is crucial for developing targeted interventions. METHODS: This cross-sectional study analyzed data from the second round of Biobehavioral Survey (BBS) conducted from 2019 to 2020 in five urban areas to examine determinants of inconsistent condom use and risky sexual behaviors among FSWs. Modified Poisson regression models were used to assess the effect of various socio-demographic, economic, and behavioral factors on the outcomes, providing adjusted relative risk (aRR) with 95% confidence intervals (CI). RESULTS: Among the 2,565 FSWs who reported inconsistent condom use, younger FSWs (15-24 years old, 29.1%), single (27.3%), with secondary or higher education (26.1%), nationals (25.9%), and residents of Tete City (30.5%) had a higher prevalence of inconsistent condom use. Initiating sex work < 18 years (31.0%), binge drinking (23.7%), and experiencing physical violence (29.0%) were significantly associated with this behavior. Among the 2,564 FSWs reporting risky sexual behaviors, a higher prevalence was observed in FSWs aged 15-24 (75.6%), those with secondary or higher education (75.8%), nationals (74.4%), and those residing in Quelimane (87.3%). Early sexual debut (< 15 years, 79.3%), initiating sex work before 18 years of age (77.7%), and illicit drug use (82.2%) were all associated with increased risky sexual practices. Inconsistent condom use among FSWs was significantly associated with residing in Tete (aRR = 2.4, 95% CI: 1.77-3.25), not being aware of female condom (aRR = 1.22, 95% CI: 1.03-1.45) and having experienced sexual a physical violence. Moreover, being married was significantly linked to risky sexual behavior among female sex workers (aRR = 1.27, 95% CI: 1.19-1.37), along with initiating sexual activity before age 15, having at least five years of sex work experience, engaging in binge drinking, and experiencing sexual and physical violence. CONCLUSION: The study highlights the complex set of factors as age, education, geographic location, years of sex work services, early sexual debut, and illicit drug use that influence sexual risks behavior among FSWs in Mozambique. Tailored interventions addressing not only sexual health education and services, but also economic empowerment and illicit drug use is imperative for mitigating these risks.

Characteristics associated with viral suppression among HIV-infected children aged 0-14 years in Mozambique, 2019.

The human immunodeficiency virus (HIV) is a global public health problem, disproportionally affecting sub-Saharan African countries including Mozambique. In 2019, of 150,000 estimated HIV-infected children in Mozambique, only 95,080 were on antiretroviral treatment and 73% virally suppressed. The objective of this study was to determine the characteristics associated with viral suppression in children. A cross-sectional study was carried out using records of viral load samples from children aged 0 to 14 years old who underwent viral load tests in 2019 in Mozambique. Secondary analyses were conducted on data obtained from Data Intensive Systems and Applications (DISA) of children enrolled in health facilities who had viral load tests registered. Viral suppression was defined as the presence of less than 1,000 copies/ml of blood. Multivariate logistic regression analysis was used to evaluate the characteristics associated with viral suppression. Of the 33,559 viral load sample records analyzed, 53% (17,794/33,559) were female. The average patient age was 8 (sd ± 4) years old. About 44% (14,888/33,559) of the children had a suppressed viral load, with 55% (8,258/14,888) being female and 16% (2,319/14,888) belonging to the 1-4 years old age group. Characteristics associated with viral suppression were the age groups of 5-9 years [AOR = 1.73; 95% CI 1.34-2.23; p<0.001] and 10-14 years old [AOR = 1.92; 95% CI 1.50-2.48; p<0.001] versus < 1 year. Other factors such as living in Maputo City [AOR = 1.61; 95% CI 1.26-2.05; p <0.001] versus Tete Province were also associated with viral suppression. Factors such as being male [AOR = 0.83; 95% CI 0.80-0.87; p <0.001)], living in the provinces of Niassa [AOR = 0.75; 95% CI 0.56-0.99; p <0.003], Cabo Delgado [AOR = 0.77; 95% CI 0.60-0.99; p <0.045] and Zambezia [AOR = 0.72 (95% CI: 0.56-0.92, p<0.008)] versus Tete Province, or being on ART for 2-5 years [AOR = 0.72 (95% CI: 0.61-0.85, p<0.001)] versus 11-14 years were associated with not being virally suppressed. More than half of children did not achieve viral suppression. The odds of viral suppression were highest among children aged 5-14 years and among children living in Maputo city. Further research is needed to better understand the challenges in achieving viral suppression in children.

Clinical-epidemiological profile and factors associated with viral non-suppression in patients living with HIV/AIDS assisted at the Integrated Treatment Center at the Maputo Military Hospital (CITRA/MMH), 2019 to 2020.

BACKGROUND: HIV remains a critical global public health challenge. In 2022, it was estimated that approximately 39.0 million people worldwide were living with HIV, and of these, around 29.8 million were receiving antiretroviral therapy (ART). The objective was to evaluate the clinical and epidemiological profile and factors associated with viral load (VL) non-suppression in people living with HIV/AIDS at the Maputo Military Hospital (CITRA/MMH). METHODS: A retrospective cross-sectional analytical study was conducted on 9105 people aged 15 years and over. We use secondary data from participants on ART for at least 2 years being followed up between the years 2019-2020 at CITRA/MMH. Those recently enrolled (on ART < 1 year) were excluded and data analysis was performed using STATA version 16. Pearson's chi-square test and logistic regression were used for statistical modeling of viral non-suppression with a 95%/CI confidence interval and p < 0.05. RESULTS: Among a total of 9105 HIV participants included, 52.8% (n = 4808) were female and 13.6% (n = 1235) were military personnel. The average age was 47.9 years (standard deviation ± 12.1), with the most prevalent age group being individuals aged between 25 and 59, totalizing 7,297 (80.2%) participants. Only 5395 (100%) participants had VL results. Among these, 23.1% (n = 1247) had a result VL non-suppressed. Single marital status (Adjusted Odds Ratio [AOR] = 4.8, 95%CI: 3.93-5.76, p < 0.001), with active tuberculosis (AOR = 4.6, 95%CI: 3.15-6.63, p < 0.001) and current ART regimen in categories TDF + 3TC + EFV (AOR = 12.7, 95%CI: 9.74-16.63, p < 0.001), AZT + 3TC + NVP (AOR = 21.8, 95% CI: 14.13-33.59, p < 0.001) and "other" regimens (AOR = 25.8, 95%CI: 18.58-35.80, p < 0.001), when compared to the TDF + 3TC + DTG regime, were statistically significant for viral non- suppression. CONCLUSION: The study highlights the crucial role of ART adherence and ongoing monitoring to achieve viral suppression, particularly among adults aged 25 to 59. It underscores the need for transitioning eligible individuals to DTG-based regimens and addressing the implications of single marital status and comorbid conditions like active tuberculosis. The study emphasizes the importance of ARV adherence and continuous monitoring to meet the UNAIDS 95-95-95 targets and improve clinical outcomes for people living with HIV/AIDS.

HIV prevalence and associated factors among married women, Mozambique, 2015: analysis of the 2015 National AIDS Indicator Survey (IMASIDA).

Introduction: epidemiological estimates from the 2021 Joint United Nations Program on HIV/AIDS (UNAIDS) emphasize the existing gender disparities, where women face a higher risk of HIV/AIDS exposure. In Mozambique, as of 2021, the HIV prevalence rate among the adult population stood at 12.5%, with an even more concerning rate of 15.4% among women of reproductive age. Methods: a cross-sectional study was carried out with secondary data from the Survey on National Indicators of Vaccination, Malaria, and HIV/AIDS (IMASIDA 2015), where we included married women, both civil marriage and common law marriage of reproductive age 15-49 years. Statistical analyses, including chi-squared tests and logistic regression models, accounting for survey design, were employed to assess associations. Results: the study findings showed that HIV prevalence was higher among married women aged 35-49 years (aOR=2.5; 95% CI: 1.3-4.6; p=0.005), those without formal education (aOR=7.7; 95% CI: 1.1-52.9; p=0.038) and those with primary education (aOR=9.8; 95% CI: 1.6-60.1; p=0.014), those who experienced domestic violence (aOR=1.8; 95% CI: 1.0-3.2; p=0.04), had an uncircumcised partner (aOR=1.9; 95% CI: 1.2-3.1; p=0.008), and had three or more lifetime sex partners (aOR=3.6; 95% CI: 2.9-7.3; p<0.001). Women who were in one lifelong union had a lower risk of HIV positivity (aOR=0.5; 96%CI: 0.3-0.8, p=0.005). Conclusion: the findings of this study highlight sociodemographic, behavioral, and violent factors associated with HIV prevalence among women. These findings underscore the importance of targeted interventions and education programs aimed at reducing HIV transmission among females and promoting safer sexual practices.

Trends in HIV prevalence and risk factors among men who have sex with men in Mozambique: implications for targeted interventions and public health strategies.

BACKGROUND: Men who have sex with Men (MSM) are known to contribute to increased HIV prevalence as an integral part of key populations with high vulnerability to HIV/AIDS due to their sexual behaviours. Mozambique conducted two rounds of bio-behavioral surveys (BBS) in this population with the main objective of estimating HIV prevalence and associated risk behaviors among MSM in Mozambique. The present study aims to estimate the trend of HIV prevalence and determine the correlations of HIV infection among MSM. METHODS: A repeated cross-sectional analytical study was conducted from secondary data from the first and second rounds of BBS in Mozambique conducted in 2011 and 2020-2021 respectively. Each round used a similar methodology which allowed for comparison between the two surveys. Chi-square test and logistic regression was used to compare the HIV prevalence between the BBS rounds, identify factors associated with HIV, and assess changes in HIV prevalence across selected risk factors. RESULTS: There was a significant increase in HIV prevalence among MSM (7.1-14.9%), living in Maputo (9.3-14.7%), uncircumcised (11.7-25.1%), and those who reported two sexual partners in the last year (5.2-14.4%). In contrast, there was a decrease in prevalence among adult MSM aged between 25 and 29 years (24.7-13.9%), aged 30 years or older (45.7-27.7%), married (29.1-16.8%), with higher education (16.7-5.9%) and moderate perception of HIV risk (10.9-3.4%). Multivariable analysis showed that factors such as age, marital status, religion, sexual identity, circumcision, and the use of lubrication during anal sex are significantly associated with the risk of HIV infection. CONCLUSIONS: This study underscores the continuing need for HIV prevention and education efforts. The rise in prevalence among specific population segments and the sustained presence of risk factors emphasize the requirement for holistic strategies tailored to the unique requirements of each subgroup. Understanding trends and risk factors is crucial to guiding public health policies and designing efficacious prevention programs that aim to curtail HIV transmission while enhancing the well-being of those impacted by the condition.

Cholera and diarrheal diseases in Cuamba District, Niassa Province, Mozambique: Systematic healthcare facility-based surveillance strengthening, characteristics of suspected cholera and diarrheal patients, and incidence of diarrheal diseases.

BACKGROUND: Mozambique is one of the countries in Africa that is continuously at risk of cholera outbreaks due to poor sanitation, hygiene, and limited access to potable water in some districts. The Mozambique Cholera Prevention and Surveillance (MOCA) project was implemented in Cuamba District, Niassa Province to prevent and control cholera outbreaks through a preemptive cholera vaccination, strengthened surveillance system for cholera and diarrheal diseases, and better understanding of cholera-related healthcare seeking behavior of local populations, which may further guide the national cholera control and prevention strategies. This article presents the surveillance component of the MOCA project. METHODOLOGY/PRINCIPAL FINDINGS: A prospective healthcare facility (HCF)-based surveillance of cholera and diarrheal disease was conducted in six HCFs in the District of Cuamba from March 2019 to December 2020. A systematic surveillance procedure has been put in place with capacity building in selected sentinel HCFs and a basic microbiology laboratory established on-site. Patients presenting with suspected cholera or other diarrheal symptoms were eligible for enrollment. Clinical data and rectal swab samples were collected for laboratory confirmation of Vibrio Cholerae and other pathogens. A total of 419 eligible patients from six HCFs were enrolled. The median age was 19.8 years with a similar age distribution between sentinel sites. The majority were patients who exhibited diarrhea symptoms not suspected of cholera (88.8%; n = 410). Among those, 59.2% (210/397) were female and 59.9% (235/392) were 15 years and above. There were 2 cholera cases, coming outside of the catchment area. The incidence of diarrheal diseases ranged from 40-103 per 100,000 population. No Vibrio cholerae was isolated among surveillance catchment population and Escherichia coli spp. (82/277; 29.6%) was the most common pathogen isolated. CONCLUSION/SIGNIFICANCE: Efforts were made to strengthen the systematic surveillance of suspected cholera with standardised patient screening, enrolment, and diagnostics. The first basic microbiology laboratory in Niassa Province established in Cuamba District under the MOCA project needs to be integrated into the national network of laboratories for sustainability. No reports of laboratory confirmed cholera cases from the surveillance catchment area may be highly related to the pre-emptive oral cholera vaccine (OCV) mass vaccination campaign conducted in 2018 and the use of drugs by local populations prior to visiting the sentinel HCFs. Continued systematic cholera surveillance is needed to closely monitor the cholera endemicity and epidemics, and further evaluate the long-term impact of this vaccination. High incidence of diarrheal illnesses needs to be addressed with improved water, sanitation, and hygiene (WaSH) conditions in Cuamba District. Efforts integrated with the prioritization of prevention measures are fundamental for the control of cholera in the country.

Prevalence and correlates of hazardous alcohol drinking and drug use among female sex workers and men who have sex with men in Mozambique.

BACKGROUND: Hazardous drinking and drug consumption are associated with an increased risk of HIV due to the complex interplay of factors influencing decision-making capability, stigma and social marginalization. In this study, we explore the patterns of hazardous alcohol and drug use and correlates of risk factors among female sex workers (FSW) and men who as sex with men (MSM) in Mozambique. METHODS: We conducted a secondary data analysis of bio-behavioral surveys (BBS) among FSW and MSM using a respondent-driven sampling methodology conducted in five main urban areas of Mozambique from 2019 to 20. The survey included a standardized questionnaire, where hazardous drinking was assessed (using AUDIT-C scores ≥ 4 for men, ≥ 3 for women) and drug use in the last year (FSW). Chi-squared test was used to analyze the association between socio-demographic and behavioral variables, and multivariate logistic regression measured the impact of the associated factors. RESULTS: The prevalence of hazardous alcohol drinking was 47.1% (95% CI:44.8-49.5) for FSW and 46.5 (95% CI: 44.0-49.0) for MSM. Current drug use was reported in 13.3% of FSW. FSW engaging in hazardous alcohol drinking reported more sexual partners in the last month than those no reporting hazardous alcohol use (55.3% vs. 47,1%, p < 0.001), higher rates of self-reported STIs in the last year (62,5% vs. 48,2%, p < 0.001), physical (53.5% vs. 46.7%, p < 0.0001) and sexual violence (54.7% vs. 44.2%, p < 0.001), and HIV prevalence (55.2% vs. 44.2 p < 0.001). Among MSM with hazardous alcohol drinking, there was a higher prevalence of self-reported STIs (52.8% vs. 45.4%, p < 0.001), experiences of sexual violence (18.0% vs. 8.3%, p < 0.001), and HIV prevalence (53.0% vs. 46.3%, p < 0.001). In addition, FSW who reported illicit drug use were more likely to self-reported HIV own risk (14.2% vs. 9.7%), early start sexual activity (15.4% vs. 5.3%), self-reported STIs (17.9% vs. 10.2%), and experiences of both physical (17.4% vs. 7.0%) and sexual violence (18.6% vs. 8.9%). CONCLUSION: There is an immediate need for the introduction and integration of comprehensive substance use harm mitigation and mental health interventions into HIV prevention programs, particularly those targeting key populations in Mozambique.

People Who Inject Drugs in Mozambique: We need to normalize HIV treatment and care services in specialized community centers for people who inject drugs!

Globally, People Who Inject Drugs (PWID) have limited healthcare, treatment, and prevention services, and they frequently experience stigma and negative attitudes toward healthcare providers when accessing services. Mozambique, with a general population HIV prevalence of 12.5%, has one of the highest rates in the world, and the PWID population has the highest HIV prevalence among key populations, estimated at nearly 50%. Less than half of HIV positives who inject drugs are linked to HIV treatment and are retained in care. One of the main reasons is that HIV treatment is mainly provided in a public health facility and PWID delayed accessing healthcare since they anticipated mistreatment from multiple levels of healthcare providers. To improve the health outcomes in this group, we need to treat them where they feel comfortable and respected. In this commentary, we outline the importance of innovative approaches to enhance the management of HIV-positive PWID. As a country gets close to controlling the HIV epidemic, refocusing and targeting responses to the highest-risk groups becomes even more essential for shaping more effective HIV interventions and achieving epidemic control.

Mask use in public places in Maputo City, Mozambique: Cross-sectional survey.

INTRODUCTION: The use of face masks is one of the preventive measures that Mozambique adopted in order to limit the spread of COVID-19. A study carried out from May 25 to June 6, 2020 found that although many wore masks, incorrect use was observed in 27.5% of the population observed. This data collection aimed to measure the degree of mask use compliance during a more protracted, higher second wave of transmission. METHODOLOGY: A cross-sectional study was conducted in the City of Maputo from 19 to 28 October 2020 through direct observation of mask use of all individuals present in markets, supermarkets and bus terminals. The data were collected using mobile phones with the Open Data Kit Collect (ODK) data collection program. Sociodemographic characteristics, mask use, and type of mask used were documented. Factors associated with incorrect mask use were evaluated considering sex, age, observation period and location. RESULTS: A total of 49,404 individuals were observed, of whom 24,977(50.6%) were male, 46,484 (94.1%) were adults and 17,549 (35.5%) were observed in the markets. An observed 41,786 (84.6%) wore a mask, of whom 33,851 (81.0%) used it correctly. Not covering the mouth and nose was common; observed in 4,649 (58.5%) of those using incorrectly. Of different types of masks, fabric masks were most often used incorrectly 7,225 (21.4%). The factors associated with incorrect mask use were female gender (OR = 1.2 [1.1-1.3], p <0.001), observation in peri-urban versus urban areas (OR = 1.9 [1.8-2.1], p <0.001) and observation during the afternoon (OR = 1.5 [1.5-1.6], p <0. 001). CONCLUSION: A high proportion of observed individuals wore a mask in the context of prevention of COVID-19, however some non-use and incorrect use persists. Intensified public awareness of the correct use of the mask is recommended, especially in peri-urban areas and at the end of the day.

Pre-emptive oral cholera vaccine (OCV) mass vaccination campaign in Cuamba District, Niassa Province, Mozambique: feasibility, vaccination coverage and delivery costs using CholTool.

INTRODUCTION: Mozambique suffers from regular floods along its principal river basins and periodic cyclones that resulted in several cholera epidemics during the last decades. Cholera outbreaks in the recent 5 years affected particularly the northern provinces of the country including Nampula and Niassa provinces. A pre-emptive oral cholera vaccine (OCV) mass vaccination campaign was conducted in Cuamba District, Niassa Province, and the feasibility, costs, and vaccination coverage assessed. METHODS: WHO prequalified OCV (Euvichol-Plus), a killed whole-cell bivalent vaccine containing Vibrio cholerae O1 (classical and El Tor) and O139, was administered in two doses with a 15-day interval during 7-31 August 2018, targeting around 180 000 people aged above 1 year in Cuamba District. Microplanning, community sensitisation, and training of local public health professionals and field enumerators were conducted. Feasibility and costs of vaccination were assessed using CholTool. Vaccination coverage and barriers were assessed through community surveys. RESULTS: The administrative coverage of the first and second rounds of the campaign were 98.9% (194 581) and 98.8% (194 325), respectively, based on the available population data that estimated total 196 652 inhabitants in the target area. The vaccination coverage survey exhibited 75.9% (±2.2%) and 68.5% (±3.3%) coverage for the first and second rounds, respectively. Overall, 60.4% (±3.4%) of the target population received full two doses of OCV. Barriers to vaccination included incompatibility between working hours and campaign time. No severe adverse events were notified. The total financial cost per dose delivered was US$0.60 without vaccine cost and US$1.98 including vaccine costs. CONCLUSION: The pre-emptive OCV mass vaccination campaign in remote setting in Mozambique was feasible with reasonable full-dose vaccination coverage to confer sufficient herd immunity for at least the next 3 to 5 years. The delivery cost estimate indicates that the OCV campaign is affordable as it is comparable with Gavi's operational support for vaccination campaigns.

Conditions to eliminate cholera in Mozambique - the pathway for the development of the national cholera plan.

Cholera disproportionately affects the most vulnerable segments of the population, particularly those who have low or no access to basic water, sanitation, and hygiene (WASH). Despite some improvements in WASH conditions, cholera still represents a persistent challenge in Mozambique, where outbreaks occur almost every year, with high case fatality rates, posing a threat to the country's economic development. The Government of Mozambique has started developing a revised National Cholera Plan (NCP), which aligns with "ending cholera-a global roadmap to 2030" launched by the Global Task Force on Cholera Control (GTFCC) in 2017. Ending cholera represents a critical step towards achieving the sustainable development goals and requires effective prevention and control interventions, ensuring that no one is left behind. The NCP must use a multi-sector approach and broad stakeholder collaboration with well-coordinated roles and functions of different partners to address major areas for cholera elimination - water and sanitation, health care services and management, epidemiology and surveillance, and health and hygiene promotion. Every cholera death is preventable. In this review, we reiterate the need for effective coordinated actions to control and eliminate cholera in Mozambique and decrease the cholera burden, enabling a healthy population over the generations.

Evaluation of the Mozambique Antiretroviral Therapy (MozART) database as an antiretroviral therapy patient surveillance system, 2017-2018.

Introduction: Mozambique antiretroviral therapy is a database used to monitor patients receiving antiretroviral treatment (ART). This study's objective was to evaluate the system for the purpose to monitor patients receiving ART. Methods: data from 287,052 patients who started ART from January to December 2017 were verified, and retention in care was assessed for 2018 in Mozambique. The Centers for Disease Control and Prevention guidelines for evaluating public health surveillance systems were used to conduct the evaluation. Simplicity, flexibility, data quality, representativeness and stability attributes were evaluated. Results: a total of 93% (266,880/287,052) of patients on ART were adults ≥15 years old, and 65% (186,677/287,052) were female. The system was complex, it involved four organisations and its management was online. Data quality was moderate with 19% (1,533,885/8,037,456) of empty variable fields, 0.04% (123/287,052) observations with birth date later than the initial ART date, 0.2% (424/287,052) and 23% (68,039/287,052) with initial ART date and diagnosis date, later than the next ART pickup date. Nationally, 19%(31/161) of the districts did not have data in the information system. MozART cover health facilities with electronic patient tracking systems. Hence did not represent all patients on ART. While it was not possible to add variables of the electronic patient tracking, the system was stable as neither data or server interruptions were reported. Conclusion: the system was useful, stable, with moderate data quality, complex, not flexible and not representative. We recommend to health facilities and partners to develop and distribute procedures for data validation and completeness and report all patient tracking variables in the system.

Investigation and contact tracing of the first cases of COVID-19 in Mozambique, 2020.

Introduction: contact tracing is an important strategy to interrupt the spread of infectious disease and prevent new cases. After the confirmation of the first positive case of COVID-19 in Mozambique on March 22, 2020, case investigation and contact tracing were immediately initiated, which included clinical and laboratory monitoring of cases and contacts throughout the quarantine period. We aim to describe the methodology and impact of early investigation and contact tracing. Methods: in the context of implementation of the national COVID-19 preparedness and response plan, guidelines and forms for contact tracing were adapted from the existing World Health Organization (WHO) and The Centers for Disease Control and Prevention (CDC) guidelines. The case definition used was "patient with travel or residency history in a country reporting local transmission of COVID-19 during the 14 days prior to the onset of symptoms". The cases interviews were face to face and contacts were followed up daily by phone calls for 14 consecutive days: using a structured questionnaire. Data were entered in an electronic Excel database. We collected samples for diagnosis of those who developed symptoms and provided quarantine follow up. Results: a total of 8 cases were confirmed, of which 6 (75%) were male. The average age of the cases was 51, median 44 (range: 31 to 80) years old. The majority of cases presented common symptoms of COVID-19, including headaches (50%), cough (37.5%), and fever (25%). Our case series included the country´s index case, two close positive contacts, and 5 additional cases that were not epidemiologically linked to the others and identified by the COVID-19 national surveillance system. All of them were identified in Maputo City from March 22 to March 28. Cases had a total of 123 contacts and all of them were tracked; 79 were contacts of the first case. From all the contacts in follow up, two had laboratory confirmed COVID-19. All cases and contacts were quarantined and none of them developed severe symptoms or required hospitalization. Conclusion: timely case identification and systematic contact tracing can be effective in breaking the chain of COVID-19 transmission when there is strong collaboration between epidemiological, laboratory surveillance and case management.

Evaluation of the multidrug-resistant tuberculosis surveillance system in Maputo City, Mozambique in the period 2017-2018.

Introduction: multidrug-resistant tuberculosis (MDR-TB) remains a public health problem worldwide. In Mozambique, cases of MDR-TB have increased annually. In 2018, 1,206 cases were reported, as compared to 943 cases in 2017. The aim of this study was to assess the surveillance system for multidrug-resistant tuberculosis in Maputo City. Methods: an extract from the national database was considered for a cut-out of the City of Maputo in the period 2017-2018; the study was conducted per the guidelines of the Centers for Disease Control and Prevention, where the description of the system was carried out, and evaluation of the attributes. Each attribute was evaluated according to the established criteria and parameters. Results: the surveillance system is based on the collection of data in health centers. Four hundred and six cases of MDR-TB were notified, of which 56.8% (231/406) were male and 95.9% (386/406) were ≥15 years. The system was complex with 4 levels of information transmission. With regard to flexibility, there was no changing the variables in the database. Acceptability was good. The quality of the data was regular with discrepancy of data of 14.5%. The system was considered stable as there was no system interruption. Timeliness with case notification monthly. The system sensitivity was 72.9%, the positive predictive value (PPV) was 2.3% and regarding utility the system has fulfilled its objectives. Conclusion: the system was not flexible, the data quality was regular, had moderate sensitivity and low positive predictive value. Continuous assessment of data and scale up the diagnosis for the detection of cases of MDR-TB is recommended.

Factors associated with knowledge about malaria prevention among women of reproductive age, Tete Province, Mozambique, 2019-2020.

BACKGROUND: Mozambique is a malaria endemic country with an estimated prevalence of malaria in children 6-59 months old that is twice as high in rural areas (46.0%) as in urban areas (18.0%). However, only 46.0% of women aged 15-49 years had complete knowledge about malaria in 2018. This study aimed to identify the factors associated with malaria knowledge among women of reproductive age in a high malaria burden district. METHODS: Data from a cross-sectional study, using a population-based malaria research study in Mágoe District, 2019, were analysed. This analysis included women aged 15-49 years. A multivariate logistic regression model was developed to determine factors associated with complete knowledge of malaria that calculated adjusted odds ratio (aOR) and 95% confidence interval (CI) at a p < 0.05 significance level. Complete malaria knowledge was defined as when a woman correctly identified: fever as a malaria symptom, mosquito bites as the means of malaria transmission, mosquito nets as a tool for malaria prevention, malaria as curable, and were able to name an anti-malarial. RESULTS: A total of 1899 women were included in this analysis. There was complete malaria knowledge among 49% of the respondents. Seventy one percent mentioned fever as one of malaria symptoms, 92% mentioned mosquito bite as the cause of malaria infection, 94% identified that mosquito nets prevent malaria, 92% agreed that malaria has cure, and 76% were able to name at least one anti-malarial medicine. In the multivariate analysis, the following characteristics were associated with significantly higher odds of having complete malaria knowledge: having a secondary school or above education level (adjusted Odds Ratio, aOR = 2.5 CI [1.3-4.6] p = 0.005), being from the middle socioeconomic status group (aOR = 1.5 CI [1.1-2.1] p = 0.005), being from older age group of 35-39 (aOR = 1.9; CI [1.1-3.1] p < 0.001), having 1-2 children (aOR = 1.8; CI [1.2-2.6] p = 0.003), and having interviews completed in Portuguese or Cinyungwe (aOR = 2.3; CI [1.3-4.1] p = 0.004 and aOR = 2.1; CI [1.5-2.8] p < 0.001, respectively). CONCLUSION: Most women in this study had some malaria knowledge, but gaps in complete knowledge remained. In order to broaden knowledge, educational messages about malaria prevention should be more effectively targeted to reach younger, less-educated women and in non-dominant languages.

Sociodemographic characteristics of professional categories most affected by COVID-19 in Mozambique from March to July 2020.

Introduction: the risk of a worker becoming ill due to coronavirus disease 2019 (COVID-19) is related to occupational exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to the need to restore work activities in Mozambique, the study was conducted with the aim of identifying the occupational categories most affected by COVID-19 in the former in the period from March to July 2020. Methods: this is a cross-sectional descriptive study, in which data from professions of confirmed cases of COVID-19 from 22 March to 29 July 2020 in Mozambique were analyzed. The professionals' data were reported daily by the National Institute of Health (NIH) and merged into a single database and exported to Excel, the latter categorized according to standard operating procedure (SOP) and descriptive statistics performed for its analysis. Results: in the period under analysis, 1,127 professionals were diagnosed with COVID-19, divided into 11 categories. Nampula province had the highest frequency of cases with 25.00% (277). The highest frequency of cases was registered in the domestic professional category, which had 16.77% (189/1,127) with the female sex being more frequent, 79.37% (150/189); and defense and security had 14.20% (160/1,127) of cases and male gender with 91.25% (146/160); Health workers had 13.04% (147/1,127), and the maximum number of COVID-19 cases was recorded in June with 58.50% (86/147). Conclusion: the professional categories most affected by COVID-19 in the period under review correspond to those groups that carry out activities requiring a physical presence at the workplace and from this; it is recommended that professionals reinforce preventive measures.

Evaluation of the HIV drug resistance surveillance system in Mozambique, 2017-2018.

In the past ten years, the prevalence of primary Human Immunodeficiency Virus (HIV) drug resistance has ranged from zero to 25%, with higher and increasing rates in countries with access to antiretroviral therapy (ART), a specific case in Mozambique. World Health Organization (WHO) recommended that countries implement and routinely evaluate representative HIV drug resistance (HIVDR) research to monitor the emergency and transmission of HIV drug resistance mutations. This study aimed to describe the functioning of the system and also to identify gaps in the sensitivity, representativeness and quality of the data using the WHO methodology for Pre-Treatment and Acquired Approaches. We conducted a descriptive evaluation of the information system for surveillance of HIVDR in Mozambique in 2017-2018, based on updated guidelines for evaluating of public health surveillance systems from the Center for Disease Control and Prevention (CDC). The evaluation was conducted in all provinces using secondary data extracted from a cross-sectional survey database on HIVDR, with HIV positive cases at the beginning of ART aged ≥15 years. The system was described through informal conversations with HIVDR stakeholders and the simplicity, data quality and representativeness attributes were evaluated. With 322 positive cases at the beginning of ART (mean age=32.5 years, SD±11.1), about 63.0% (203/322) cases were women and 37.6% (121/322) men. The system was implemented in 25 health facilities distributed across all 11 Mozambican provinces and was considered representative. The system used two data collection instruments, the ART book and the form accompanying samples sent to the reference laboratory. The ART form, with 27 variables, was sent offline at two levels (health facility and National Institute of Health (NHI)), accompanied by dried blood spot samples for viral load testing and genotyping in the NHI virology laboratory, and was considered simple according to the standardized criteria. The system´s data quality was considered regular at 79.9%, with about 59.8% (1156/1932) of variable fields completed and 100% (1932/1932) consistency. The system used a single national laboratory to measure the prevalence of resistance to HIV drugs and was considered simple, with regular quality and representative data. We recommended public health efforts such as conducting genotyping tests be expanded to the provincial level, and periodic monitoring of system´s data collection procedures using forms.

Evaluation of the health information system for monitoring and evaluating the voluntary medical male circumcision program in Mozambique, 2013-2019.

Introduction: the prevalence of human immunodeficiency virus (HIV) in Mozambique has increased from 11.5% in 2009 to 13.2% in 2015. The Mozambique Ministry of Health (MOH) developed a 5-year strategy (2013-2017) for male voluntary medical circumcision (VMMC) to increase in the provinces where there is the greatest number of HIV. We aimed to evaluate the health information system for monitoring and evaluating VMMC in Mozambique from 2013-2019. Methods: we reviewed the records of the National Health Information System for Monitoring and Evaluation (SIS-MA) database for VMMC of the MOH. The evaluation was based on the updated guidelines for the evaluation of public health surveillance systems of the Centers for Disease Control and Prevention. Results: the coverage rate for VMMC in Mozambique in the period under study was (89%) (1,784,335/2,000,000). The system was expected to circumcise for the year 2019 (162,052) and 390,590 was reached, exceeding the target 241.0% (390,590/162,052). Of the total number of men circumcised, 0.7% (12,391/1,784,335) were HIV-positive (previously tested) and 0.4% (6,382/1,784,335) had a record of adverse events in the period under review (2013-2019). Zambézia Province had the highest VMMC coverage (in numbers) at 16.0% (396,876/2,476,395) while Maputo City had the least 19.7% (107,104/543,096). The system was able to operate both online and offline and continue functioning with introducing new changes (e.g. the new male circumcision complication reporting). Conclusion: the system was representative, flexible, simple, with good data quality and low acceptability. We recommended continuous and routine entry of quality data into the system, guide organizations for improved functioning.

Young key populations left behind: The necessity for a targeted response in Mozambique.

INTRODUCTION: The first exposure to high-risk sexual and drug use behaviors often occurs during the period of youth (15-24 years old). These behaviors increase the risk of HIV infection, especially among young key populations (KP)-men how have sex with men (MSM), female sex workers (FSW), and people who inject drugs (PWID). We describe the characteristics of young KP participants in the first Biobehavioral Surveillance (BBS) surveys conducted in Mozambique and examine their risk behaviors compared to adult KP. METHODS: Respondent-driven sampling (RDS) methodology was used to recruit KP in three major urban areas in Mozambique. RDS-weighted pooled estimates were calculated to estimate the proportion of young KP residing in each survey city. Unweighted pooled estimates of risk behaviors were calculated for each key population group and chi-square analysis assessed differences in proportions between youth (aged less than 24 years old) and older adult KP for each population group. RESULTS: The majority of MSM and FSW participants were young 80.7% (95% CI: 71.5-89.9%) and 71.9% (95% CI: 71.9-79.5%), respectively, although not among PWID (18.2%, 95% CI: 13.2-23.2%). Young KP were single or never married, had a secondary education level or higher, and low employment rates. They reported lower perception of HIV risk (MSM: 72.3% vs 56.7%, p<0.001, FSW: 45.3% vs 24.4%, p<0.001), lower HIV testing uptake (MSM: 67.5% vs 72.3%, p<0.001; FSW: 63.2% vs 80.6%; p<0.001, PWID: 53.3% vs 31.2%; p = 0.001), greater underage sexual debut (MSM: 9.6% vs 4.8%, p<0.001; FSW: 35.2% vs 22.9%, p<0.001), and greater underage initiation of injection drug use (PWID: 31.9% vs 7.0%, p<0.001). Young KP also had lower HIV prevalence compared to older KP: MSM: 3.3% vs 27.0%, p<0.001; FSW: 17.2% vs 53.7%, p<0.001; and PWID: 6.0% vs 55.0%, p<0.001. There was no significant difference in condom use across the populations. CONCLUSION: There is an immediate need for a targeted HIV response for young KP in Mozambique so that they are not left behind. Youth must be engaged in the design and implementation of interventions to ensure that low risk behaviors are sustained as they get older to prevent HIV infection.
