Pattern of intestinal parasitic infections in children with malnutrition in Somalia.

Objectives: Children living in conflict zones plagued with adverse climatic conditions often suffer from acute malnutrition. Being coinfected with intestinal parasites could worsen the prognosis if adequate interventions are not promptly instituted. We determined the pattern of intestinal parasitic infections (IPIs) in children with acute malnutrition in the Bay and Banadir regions of Somalia. Methods: A hospital-based cross-sectional study was conducted from August to October 2023 in 222 children with acute malnutrition aged 6-59 months, using a structured questionnaire and stool examination by a trained laboratorian. The prevalence of IPI was estimated and the pattern of IPI was explored. The relationship between the presence of IPI and demographic characteristics was examined with multiple logistic regression at a 95% level of confidence. Results: The mean age was 20.4 ± 12.3 months, 125 (56.3%) were females, and 41.9% were internally displaced. The prevalence of IPI was 82.9% (95% confidence interval: 77.4-87.3), Of the infected, 73.9% (136 of 184) had single parasitic infection and 23.4% (43 of 184) had double parasitic infections. Ascaris lumbricoides (46.6%), Giardia lamblia (22.1%), and Entamoeba histolytica (17.6%) were the most common parasites identified. The age of 13-36 months (adjusted odds ratio: 1.13, P = 0.02) and eating once a day (adjusted odds ratio: 1.13, P = 0.06) were associated with being infected with intestinal parasites. Conclusions: The prevalence of intestinal parasitic infection was high in children with malnutrition in the Bay and Banadir regions. Deworming should be extended to all children with malnutrition. Food, sanitation, and water provision initiatives should be improved at the community level.

COVID-19 pandemic response and Field Epidemiology and Laboratory Training Programs in ECOWAS.

The COVID-19 pandemic has been persistent with a huge demand for human health resources which is a vital component of its preparedness and response. Globally, the public health workforce through field epidemiology and laboratory training programme (FELTP) has been instrumental to global health security. We determined the status of FELTP in the region and its contributions to the COVID-19 pandemic response in the ECOWAS region. We conducted a desk review, shared a questionnaire among member states and organized a two-day online regional consultative meeting on field epidemiology training on 30th-31st March 2022 during which there were presentations, group discussions and deliberations on the status and contribution of FETP during the COVID-19 pandemic. Data collected were analyzed in themes. All countries in the ECOWAS region had established at least one tier of FELTP, 11 (73.3%) had established two tiers of FELTP and only 3 (20.0%) had established all three tiers of the program. Despite the pandemic, the cumulative number of graduates increased from 2996 to 4271 frontline, 41 to 380 intermediate, and 409 to 802 for advanced FELTP between 2019 and 2022. However, the progress has been disproportionate across countries. The key activities supported through FELTP graduates included pandemic response coordination, surveillance, data collection/management, laboratory support, case management, risk communication, infection prevention and control, COVID-19 vaccination, and research. Despite improvements in the FELTP in the Economic Community of West African States (ECOWAS) region, there is a need for continuous stakeholder engagement for its implementation, resource mobilization for sustainability, and leveraging critical partnerships.

Maternal death surveillance and response system evaluation in Makonde District, Zimbabwe, 2021.

BACKGROUND: Maternal mortality is of global concern, almost 800 women die every day due to maternal complications. The maternal death surveillance and response (MDSR) system is one strategy designed to reduce maternal mortality. In 2021 Makonde District reported a maternal mortality ratio of 275 per 100 000 and only sixty-two percent of deaths recorded were audited. We evaluated the MDSR system in Makonde to assess its performance. METHODS: A descriptive cross-sectional study was conducted using the CDC guidelines for evaluating public health surveillance systems. An Interviewer-administered questionnaire was used to collect data from 79 health workers involved in MDSR and healthcare facilities. All maternal death notification forms, weekly disease surveillance forms, and facility monthly summary forms were reviewed. We assessed health workers' knowledge, usefulness and system attributes. RESULTS: We interviewed 79 health workers out of 211 workers involved in MDSR and 71 (89.9%) were nurses. The median years in service was 8 (IQR: 4-12). Overall health worker knowledge (77.2%) was good. Ninety-three percent of the deaths audited were of avoidable causes. Twelve out of the thirty-eight (31.6%) facilities were using electronic health records system. Feedback and documented shared information were evident at four facilities (21%) including the referral hospital. Nineteen (67.9%) out of 28 maternal death notification forms were completed within seven days and none were submitted to the PMD on time. CONCLUSION: The MDSR system was acceptable and simple but not timely, stable and complete. Underutilization of the electronic health system, work load, poor documentation and data management impeded performance of the system. We recommended appointment of an MDSR focal person, sharing audit minutes and improved data management.

Adverse drug reactions, adherence, and virologic outcomes in adult patients on dolutegravir-based antiretroviral therapy at a tertiary hospital, southeast Nigeria.

Objective: To assess the adherence, adverse drug reactions (ADR), and virologic outcomes of dolutegravir-based antiretroviral therapy. Design: This was a retrospective chart review. Setting: A tertiary health facility-based study in Abakaliki, Nigeria. Participants: Five hundred and fifteen (515) adult patients on dolutegravir were selected using a Random Number Generator. Demographic and clinical data were extracted from patients' case notes and analysed with IBM-SPSS version-25. Main outcome measures: Adherence to dolutegravir, ADRs, virologic outcome, and change in Body Mass Index (BMI) were estimated. Results: The mean age of the patients was 45.5±10.8 years; 68.2% of them were females; 97.1% of them had good self-reported adherence. The majority (82.9%) of them reported no ADRs and among those (17.1%) that did, headache (9.7%), body-itching (3.1%), and skin rash (2.7%) dominated. Most achieved viral suppression (94.4%) and did not have detectable viral particles (57.4%). There was a significant increase in the BMI of the patients with a mean weight increase of 0.9kg, a mean BMI increase of 0.3 kg/m2, and a 2.6% increase in the prevalence of overweight and obesity. Conclusions: Patients on dolutegravir reported low ADRs, good self-reported adherence, and a high viral suppression rate. However, dolutegravir is associated with weight gain. We recommend widespread use and more population-wide studies to elucidate the dolutegravir-associated weight gain. Funding: None declared.

Maternal mortality review in a major tertiary referral hospital in Liberia, 2018-2021.

Objectives: Anecdotal evidence showed increased maternal deaths at the major tertiary hospital over the past two years (2020-2021). We reviewed the maternal death audit data, identified the main causes of maternal death, and associated risk factors. Findings were shared with policymakers to help reduce maternal mortality. Study design: We conducted a secondary data review and descriptive analysis of maternal death at the tertiary hospital located in Monrovia. Method: The maternal death data were extracted from patient medical records, including death certificates and maternal audit records. The record of live births was obtained from the delivery register. Data were analyzed using Epi Info version 7.2 Maternal mortality ratio (MMR) was estimated, the leading direct and indirect causes of maternal death were identified, and the factors associated with maternal death were explored using logistic regression at a 5% level of significance. Results: There are a total of 233 maternal deaths and 14, 879 live births giving a maternal mortality ratio (MMR) of 1565 per 100,000 live births during the period under review. The median age of the mothers at death was 29 (14-45) years. About 40.3% (94/233) of cases died within <1 day of admission, referrals accounted for 59% (137/233) of the cases. Direct causes of death accounted for 66% (147/223). Hemorrhage [30.6% (45/147)], Eclampsia [(30/147) 20.6%] and Sepsis [(30/147) 20.6%] were the main direct causes of death while cardiovascular-related [18.4% (14/76)] and HIV/AIDS [16% (12/76)] were the leading indirect cause of death. Patients from referred other facilities were 7.9 times more likely to die as compared to non-referral (pOR:7.9, 95%CI: 5.9-10.6, p < 0.001). Conclusion: The maternal mortality ratio remained high. Referrals were done late. The Liberia Ministry of Health should equip more secondary-level health facilities and tertiary hospitals to handle maternal emergencies and sensitize the populace and healthcare workers on prompt identification and referral of obstetric emergencies. The MoH also needs to improve the blood transfusion services to help in the management of postpartum hemorrhage.

Trend of Lassa fever cases and factors associated with mortality in Liberia, 2016 - 2021: a secondary data analysis.

Introduction: Lassa fever (LF) is endemic in Liberia and is immediately reportable. Suspected cases are confirmed at the National Public Health Reference Laboratory. However, there is limited information on the trend and factors associated with mortality. We described the epidemiological characteristics of LF cases and determined factors associated with mortality in Liberia from 2016 to 2021. Methods: we reviewed 867 case-based LF surveillance data from 2016 to 2021 obtained from the National Public Health Institute of Liberia (NPHIL). The cases that met the suspected LF case definition were tested with RT-PCR. Using Epi Info 7.2.5.0. We conducted univariate, bivariate, and multivariate and analysis. We calculated frequencies, proportions. Positivity rate, case fatality rate, and factors associated with LF mortality using chi-square statistics and logistics regression at 5% level of significance. Results: eighty-five percent (737/867) of the suspected cases were tested and 26.0% (192/737) were confirmed LF positive. The median age of confirmed LF cases was 21(IQR: 12-34) years. Age 10-19 years accounted for 24.5% (47/192) and females 54.2% (104/192). Bong 33.9% (65/192), Grand Bassa 31.8% (61/192), and Nimba counties, 21.9% (42/192) accounted for most of the cases. The median duration from symptom onset to hospital admission was 6 (IQR: 3-9) days. A majority, 66% (126/192) of the cases were reported during the dry season (October-March) and annual incidence was highest at 12 cases per 1,000,000 population in 2019 and 2020. The overall case fatality rate was 44.8%. Non-endemic counties, Margibi, 77.8% and Montserrado, 66.7% accounted for the highest case fatality rate (CFR), while 2018, 66.7% and 2021, 60.0% recorded the highest CFR during the period. Age ≥30 years (aOR=2.1,95% CI: 1.08-4.11, p=0.027) and residing in Grand Bassa County (aOR=0.3, 95% CI: 0.13-0.73, p=0.007) were associated with LF mortality. Conclusion: Lassa fever was endemic in three of the fifteen counties of Liberia, case fatality rate remained generally high and widely varied. The high fatality of LF has been reported to the NPHIL and is currently being further investigated. There is a need to continuously train healthcare workers, especially in non-endemic counties to improve the LF treatment outcome.

COVID-19 vaccine hesitancy among adults in Liberia, April-May 2021.

BACKGROUND: Vaccination is one of the most cost-effective public health interventions used to prevent diseases in susceptible populations. Despite the established efficacy of vaccines, there are many reasons people are hesitant about vaccination, and these reasons could be complex. This rapid survey estimated the prevalence of COVID-19 vaccine hesitancy and potentially contributing factors in Montserrado and Nimba counties in Liberia. METHODS: A cross-sectional study was conducted among adults living in Liberia. The relationship between vaccine non-acceptance and sociodemographic characteristics was examined using chi-square statistics. The variables with a p-value less than 0.2 at the bivariate analysis were modelled in a binary logistic regression at a 5% level of significance. The adjusted odds ratio and 95% confidence interval are reported. RESULTS: There were 877 participants in the study. Majority were 25-34 years of age (30.4%, 272/877), females (54.05%, 474/877), and Christians (85.2%, 747/877). Most of the participants were aware of the COVID-19 vaccine (75%, 656/877), single (41.4%, 363/877), self-employed (37.51%, 329/877), and live-in rural communities (56.1%, 492/877). Vaccine hesitancy was (29.1%, 255/877; 95% CI:26.2-32.2). Vaccine hesitancy was greater among adults living in urban areas (41%) compared to persons living in rural communities (59%) (aOR; 1.5, 95% CI: 1.1-2.1) and respondents aged 45-54 years (aOR:0.5; 95% CI: 0.2-0.9; p = 0.043) were 50% less likely to be hesitant to COVID-19 vaccination compared to those more than 55 years. The most common source of information was the media (53%, 492/877) and the main reason for being hesitant was a need for more information about the vaccine and its safety (84%, 215/255). CONCLUSIONS: The majority of study participants were aware of the COVID-19 vaccines and their most common source of information was the media (television, radio). Vaccine hesitancy was moderate. This could pose a challenge to efforts to control the spread of the COVID-19 pandemic. Therefore, the health authorities should provide more health education on the importance of vaccines and their safety to the populace.

Descriptive Analysis of Measles Outbreak in Liberia, 2022.

Background: Liberia reported a large outbreak of measles involving all the counties in 2022. We conducted a descriptive analysis of the measles surveillance data to understand the trend of the outbreak and guide further policy action to prevent future outbreaks. Methods: We analyzed the measles surveillance data from Epi week 1 to 51, 2022. All the laboratory-confirmed cases, clinically compatible and epidemiologically linked cases were included in the analysis, the variables of interest included the patient's age, sex, place of residence, measles classification, measles vaccination status, and outcome. We cleaned and analyzed the data using R version 4.2.0 and Arc GIS Pro. The demographic characteristics of the cases were presented, the progression of the cases was presented in Epicurve and the spatial distribution and the case fatality rate (CFR) of the case were presented at the district level using the Arc GIS Pro. Results: The median age of the cases was 4 years (interquartile range: 2-8 years). Children under five years of age constituted 60% of the cases (4836/8127), and females accounted for 52% (4204/8127) of the cases. Only 1% (84/8127) of the cases had documentary evidence of receiving at least one dose of measles-containing vaccine (MCV). Only 3 out of 92 health districts in the country did not report a case of measles during the period under review. The overall cases fatality rate was 1% however CFR of up to 10% were reported in some districts. Conclusion: The outbreak of measles involved almost all the districts of the country, exposing a possible nationwide suboptimal immunization coverage for MCV. The high CFR reported in some districts needs further investigation.

Tuberculosis cohort analysis in Zimbabwe: The need to strengthen patient follow-up throughout the tuberculosis care cascade.

INTRODUCTION: Globally people with tuberculosis (TB) continue to be missed each year. They are either not diagnosed or not reported which indicates possible leakages in the TB care cascade. Zimbabwe is not spared with over 12000 missed cases in 2020. A preliminary review of TB treatment outcomes indicated patient leakages throughout the presumptive cascade and undesirable treatment outcomes in selected cities. Chegutu District had pre-diagnosis and pretreatment losses to follow-up while Mutare City among others had 22.0% of outcomes not evaluated in the second quarter of 2021, and death rates as high as 14% were recorded in Gweru District. The problem persists despite training on data analysis and use. The TB cohorts were analysed to determine the performance of the care cascade and the spatial distribution of treatment outcomes in Zimbabwe. METHODS: Using data from district health information software version 2.3 (DHIS2.3), a secondary data analysis of 2020 drug-sensitive (DS) TB treatment cohorts was conducted. We calculated the percentage of pre-diagnosis, and pre-treatment loss to follow-up (LTFU). For TB treatment outcomes, 'cured' and 'treatment completed' were categorized as treatment success, while 'death', 'loss to follow-up (LTFU), and 'not evaluated' were categorized as undesirable outcomes. Univariate analysis of the data was conducted where frequencies were calculated, and data was presented in graphs for the cascade, treatment success, and undesirable outcomes while tables were created for the description of study participants and data quality. QGIS was used to generate maps showing undesirable treatment outcomes. RESULTS: An analysis of national data found 107583 people were presumed to have TB based on symptomatic screening and or x-ray and 21.4% were LTFU before the specimen was investigated. Of the 84534 that got tested, 10.0% did not receive their results. The treatment initiation rate was 99.1%. Analysis of treatment outcomes done at the provincial level showed that Matabeleland South Province had the lowest treatment success rate of 77.3% and high death rates were recorded in Matabeleland South (30.0%), Masvingo (27.3%), and Matabeleland North (26.1%) provinces. Overall, there were high percentages of not-evaluated treatment outcomes. CONCLUSION: Pre-diagnosis LTFU was high, and high death and loss to follow-up rates were prevalent in provinces with artisanal and small-scale mining (ASM) activities. Unevaluated treatment outcomes were also prevalent and data quality remains a challenge within the national TB control program. We recommended strengthening patient follow-up at all levels within the TB care cascade, strengthening capacity-building for data analysis and use, further analysis to determine factors associated with undesirable outcomes and a study on why LTFU remains high.

HIV and AIDS-related knowledge, HIV risk perception, uptake of HIV testing and its predictors among prison inmates in Bauchi State, Nigeria: a cross-sectional study.

Introduction: globally, HIV infection among prison inmates is significantly higher than in the general population. Therefore, it is important to identify inmates-living-with-HIV, through HIV-testing, in keeping with the target of UNAIDS vision 90-90-90. We assessed HIV/AIDS-related knowledge, HIV-risk perception and predictors of HIV-testing-uptake in Bauchi Prison. Methods: we conducted a cross-sectional study among 310 inmates selected with 2 stage sampling. Data was collected using a pretested, structured, interviewer-administered questionnaire. Inmates that consented to HIV-test were tested. We estimated inmates' knowledge about HIV/AIDS, the level of HIV testing uptake and predictors of HIV testing-uptake using multiple logistic regression at 5% significant level. Results: the mean age (SD) was 32.3 (±9.4) years and 94.8% were males, 47.1% (95% CI: 41.6-52.7) of the respondents had good knowledge of HIV/AIDS. Fifty-five percent (95% CI: 49.9-60.9) felt they were not at risk of contracting HIV. Uptake of HIV-testing was 58.1% (95% CI: 52.5-63.4). Independent predictors for the uptake of HIV-testing were age 35-44 years (aOR= 3.3; 95% CI: 1.4-7.7), positive risk perception (aOR= 3.3; 95% CI: 1.8-6.2), good knowledge of HIV (aOR= 9.6; CI: 5.1-18.0) and knowing someone who had died of AIDS (aOR= 4.1; 95% CI: 1.9-6.4). Conclusion: good knowledge of HIV/AIDS and HIV-testing-uptake was low among the inmates. We recommended the development and implementation of targeted HIV-testing interventions that cater to the specific needs of different age-groups within the prison population. The prison authority should develop prison-specific health education programme and awareness campaigns aimed at promoting accurate HIV-risk perception, improving their knowledge and help inmates make informed decisions that will prevent them from contracting HIV.

Pattern of antimicrobial prescription in Africa: a systematic review of point prevalence surveys.

Introduction: inappropriate use of antimicrobials is a cause for concern and contributes to the global antimicrobial resistance crises especially in Africa. This review aims to summarize the available evidence on the point prevalence and pattern of antimicrobial and/or antibiotic prescription in Africa. Methods: this review was carried out between April and September 2021 and identified published studies up until March 2021 on the point prevalence of antibiotic and/or antimicrobial use in Africa. Sources searched were OVID, PubMed, EMBASE, CINAHL, Web of Science, Google Scholar, Google, and African Journal Online (AJOL). Observational studies that reported prevalence published in English language were included. Covidence systematic review software was used for this review. A form for data extraction using domains culled from the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) was developed on Covidence. Screening of studies for eligibility was done independently by two reviewers. Critical Appraisal tool for use in Joanna Briggs Institute (JBI) Systematic Reviews for prevalence studies was used for quality appraisal. Results: a total of 17 studies that met the inclusion criteria were included in the review. The overall prevalence of antimicrobial/antibiotic use among inpatients in these studies ranged from 40.7% to 97.6%. The median antimicrobial/antibiotic use was 61.3 [IQR= 45.5-72.1]. The highest use of antimicrobials was reported among studies from Nigeria with a prevalence of 97.6%. The most prescribed antibiotics were the beta-lactam penicillin (Amoxicillin, clavulanic acid) (86.9%), and third generation cephalosporins (55.0%). There was general preference for parenteral route of administration of the antimicrobial agents (40-70%). Use for community acquired infections (28.0-79.5%) was the main reason for use. Majority of the prophylactic use of antimicrobial agents were for surgical prophylaxis. Conclusion: the high prevalence of antimicrobial use in Africa reinforces the need for continued surveillance and concerted efforts to institutionalize and support antimicrobial stewardship for prescribers in health institutions in the African region.

Readiness, barriers, and attitude of students towards online medical education amidst COVID-19 pandemic: A study among medical students of Ebonyi State University Abakaliki, Nigeria.

INTRODUCTION: The COVID-19 pandemic caused massive disruption to medical education in Nigeria, necessitating the call for online medical education in the country. This study assessed the readiness, barriers, and attitude of medical students of Ebonyi State University Abakaliki, Nigeria, to online medical education. METHODS: A cross-sectional study design was employed. All matriculated medical students of the university participated in the study. Information was obtained using a pre-tested, semi-structured questionnaire which was self-administered. Good attitude towards information and communication technology (ICT) based medical education was determined by the proportion of respondents correctly answering 60% of nine variables. Readiness for online classes was determined by the proportion of students who preferred either a combination of physical and online lectures or only online medical education amidst the COVID-19 pandemic. Chi-square test and multivariate analysis using binary logistic regression analysis were used in the study. A p-value of <0.05 determined the level of statistical significance. RESULTS: Four hundred and forty-three students participated in the study (response rate; 73.3%). The mean age of the students was 23.0±3.2 years. The majority of the respondents, 52.4%, were males. The students' most preferred sources for studying before the COVID-19 pandemic included textbooks, 55.1% and lecture notes, 19.0%. The commonly visited websites included Google, 75.2%, WhatsApp, 70.0% and YouTube, 59.1%. Less than half, 41.1%, have a functional laptop. The majority, 96.4%, have a functioning email address, while 33.2% participated in a webinar during the COVID-19 pandemic. Though 59.2% had a good attitude towards online medical education, only 56.0% expressed readiness for online medical education. The major barriers to online medical education included poor internet connectivity, 27.1%, poor e-learning infrastructure, 12.9% and students not having laptops, 8.6%. Predictors of readiness for online medical education included previous participation in a webinar, AOR = 2.1, (95%CI: 1.3-3.2) and having a good attitude towards IT-based medical education, AOR = 3.5, (95%CI: 2.3-5.2). CONCLUSIONS: The majority of the students showed readiness for online medical education. Lessons from COVID-19 pandemic necessitate the initiation of online medical education. University authorities should ensure that every enrolled medical student owns or have access to a dedicated laptop through a university-mediated arrangement. Adequate attention should be given to the development of e-learning infrastructure, including steady internet services within the confines of the university.

Antimicrobial use among paediatric inpatients in a Nigerian tertiary hospital: A three-year point prevalence survey.

Aim: Antimicrobials are among the most widely prescribed therapeutic agents among paediatric population. Irrational use of these agents increases the risk of antimicrobial resistance. We described the prevalence and pattern of antimicrobial use among paediatric inpatients from 2017 to 2019. Subject and Method: The study was a repeated point prevalence survey over a 3-year period using the global point prevalence standardized tools among all paediatric inpatients. The prevalence of antimicrobial use, the prescription indicators and patterns of antimicrobial use were estimated. Result: Among 191 paediatric inpatients assessed, the 3-year period prevalence antimicrobial use was 85.9% (164/191) with prevalence of 80.6% in 2017, 94.6% in 2018, and 83.6% in 2019. Antimicrobial agents used ranged from one agent (20.1%) to five different agents (5.5%). Parenteral route (66.6%) was the preferred route of administration. The reason for the use of antimicrobial agents (92.6%) and the stop/review date (99.5%) were mostly well documented. Only 4.5% of the antimicrobial use were targeted. There were no antimicrobial guidelines or policy guiding the use of antimicrobial agents, except the national guideline on the treatment of malaria and tuberculosis. Ceftriaxone, a third generation cephalosporin was the most commonly used agent across the period under review. Community-acquired infection was the commonest indication for antimicrobial use. Conclusion: Our findings of high antimicrobial prevalence has raised the attention for the need to develop hospital-based antimicrobial guideline and antimicrobial stewardship program to protect the vulnerable children, their contacts and the environment from the impact of antimicrobial resistance.

Capacity building at points of entry during COVID-19 pandemic: harmonising training curriculum for Economic Community of West African States.

This paper describes the process for developing, validating and disseminating through a train-the-trainer (TOT) event a standardised curriculum for public health capacity building for points of entry (POE) staff across the 15-member state Economic Community of West African States (ECOWAS) that reflects both international standards and national guidelines.A five-phase process was used in developing the curriculum: phase (1) assessment of existing materials developed by the US Centers for Disease Control and Prevention (CDC), Africa CDC and the West African Economic and Monetary Union, (2) design of retained and new, harmonised content, (3) validation by the national leadership to produce final content, (4) implementation of the harmonised curriculum during a regional TOT, and (5) evaluation of the curriculum.Of the nine modules assessed in English and French, the technical team agreed to retain six harmonised modules providing materials for 10 days of intensive training. Following the TOT, most participants (n=28/30, 93.3%) indicated that the International Health Regulations and emergency management modules were relevant to their work and 96.7% (n=29/30) reported that the training should be cascaded to POE staff in their countries.The ECOWAS harmonised POE curriculum provides a set of training materials and expectations for national port health and POE staff to use across the region. This initiative contributes to reducing the effort required by countries to identify emergency preparedness and response capacity-building tools for border health systems in the Member States in a highly connected region.

Seroprevalence of poliovirus antibodies in Nigeria: refining strategies to sustain the eradication effort.

Introduction: in 2016, a switch from trivalent oral poliovirus vaccine (OPV) (containing serotypes 1,2,3) to bivalent OPV (types 1,3) was implemented globally. We assessed the seroprevalence of poliovirus antibody levels in selected Nigerian states, before and after the switch, documented poliovirus type2 outbreak responses conducted and ascertained factors associated with immunity gaps based on seroprevalence rates. Methods: we conducted a secondary analysis of stored serum samples from the 2018 Nigeria National HIV/AIDS Indicator and Impact Survey. Serum from 1,185 children aged 0-119 months residing in one southern and four northern states were tested for serotype-specific PV neutralizing antibodies; seropositivity was a reciprocal titer ≥8. We conducted regression analysis to determine sociodemographic risk factors associated with low seroprevalence using SAS 9.4. Results: children aged 24-119 months (pre-switch cohort) had seroprevalence against PV1, PV2, and PV3, of 97.3% (95% CI:96.4-98.2), 93.8% (95% CI:92.2-95.5), and 91.3% (95% CI:89.2-93.4), while children aged <24 months (post-switch) had seroprevalence of 86.0% (95% CI:81.2-90.8), 55.6% (95% CI: 47.7-63.4), and 77.2% (95% CI:71.0-83.4) respectively. Regression analysis showed age <24 months was associated with lower seroprevalence against all PV serotypes, (p<0.0001); females had lower seroprevalence against PV1 (p=0.0184) and PV2 (p=0.0354); northern states lower seroprevalence against PV1 (p=0.0039), while well-water source lower seroprevalence against PV3 (p=0.0288). Conclusion: this study showed high seroprevalence rates against PV 1, 2, and 3 in pre-switch children (aged 24-119 months). However, post-switch children (<24 months) had low immunity against PV2 despite outbreak responses. Strategies to increase routine immunization coverage and high-quality polio campaigns can increase immunity against polio virus.

Anthrax outbreak investigation in Tengwe, Mashonaland West Province, Zimbabwe, 2022.

BACKGROUND: Anthrax continues to be a disease of public health concern in Zimbabwe. Between December 2021 and February 2022, Tengwe reported 36 cases of human anthrax. Gastrointestinal anthrax has the potential to cause serious outbreaks leading to loss of human life. We investigated the outbreak, identified the risk factors using one health approach to inform outbreak control. MATERIALS AND METHODS: We conducted descriptive analysis of the outbreak and a 1:2 unmatched case control study to identify risk factors for anthrax. A case was any Tengwe resident who developed an ulcer and/or abdominal symptoms and epidemiologically linked to a confirmed environmental exposure. Validated, structured interviewer-administered questionnaires were used to collect data from the cases and neighbourhood controls. Soil and dried meat samples were collected for laboratory investigations. District preparedness and response was assessed using a checklist. Data was analysed using Epi Info version 7.2.5. The odds of exposure were calculated for each risk factor examined. Multivariable logistic regression analysis was performed to identify the independent factors associated with contracting anthrax. RESULTS: Through active case finding we identified 36 cases, 31 were interviewed. Twenty-one (67.7%) were males. The median age was 33 years (Inter quartile range: 22-54). Nineteen (61.2%) cases presented with abdominal symptoms with zero deaths reported. The independent risk factor for contracting anthrax was eating under-cooked meat (aOR = 12.2, 95% CI: 1.41-105.74, p = 0.023). All samples collected tested positive for anthrax. No livestock vaccinations or zoonotic meetings were being conducted prior to the outbreak. Notification of the outbreak was done 11 days after index case presentation however one health response was instituted within 24 hours. CONCLUSION: The anthrax was confirmed in Tengwe. Consumption of under-cooked meat was associated with gastrointestinal anthrax. The timely one health response resulted in excellent outcomes. Using one health approach in managing zoonotic threats is encouraged.

Evaluation of malaria surveillance system in Benue State, Nigeria.

BACKGROUND: Malaria is a priority global health disease with high morbidity and mortality especially among children under-five and pregnant women. Malaria elimination requires an effective surveillance system. The malaria surveillance system in Benue State was evaluated to assess its attributes and performance in line with set objectives. METHODS: The updated United States Centers for Disease Control and Prevention guideline for evaluating surveillance systems was used. The surveillance system's key attributes was quantitatively and qualitatively assessed. Semi-structured questionnaires were administered to all Local Government Area (LGA) Roll Back Malaria (RBM) focal persons and five key informants were interviewed at the State level. The Benue State District Health Information System-2 (DHIS-2) malaria data and monthly summary forms were reviewed from January 2015 to December 2019. RESULTS: A total of 46 RBM focal persons and 5 key-informants participated. About 56.9% were males, the mean-age 43.8 (SD ± 9.3) years and 32 (62.8%) had ≥ 20-year experience on malaria surveillance with mean-year-experience 20.8 (SD ± 7.8) years. All 46 (100%) RBMs understood the case definition; 43 (93.5%) found it easy-to-fill the standardized data tools and understood the data flow channels. The malaria surveillance system in Benue is simple, acceptable and useful to all stakeholders, 36 (70.6%) found switching from the paper-based to the electronic-data tools with ease and 45 (88.2%) stated that analysed data were used for decision-making. Data flow from LGA to State is clearly defined, however majority of the data is collected from public health facilities through the DHIS-2 Platform. The overall timeliness and completeness of reporting was 76.5% and 95.7%, respectively, which were below the ≥ 80% and 100% targets, respectively. CONCLUSIONS: The malaria surveillance system in Benue State is simple, useful, acceptable, and flexible, but it is not representative and timely. Public-private and public-public-partnerships should be strengthened to encourage reporting from both private and tertiary health facilities and improve representativeness, and frequent feedback to improve reporting timeliness.

Are rural pregnant women disadvantaged in accessing intermittent preventive treatment in pregnancy in Ebonyi State, Nigeria?

INTRODUCTION: Adequate intermittent preventive treatment (IPTp) uptake (≥3 doses) routinely delivered at antenatal clinics is effective in preventing malaria during pregnancy. Whereas, low IPTp uptake (24.0%) had been reported among pregnant women in Ebonyi State, there is paucity of studies comparing the uptake and its predictors in the urban and rural areas of Ebonyi State. We determined IPTp uptake and its predictors in the urban and rural areas of Ebonyi State. METHODS: We conducted a cross-sectional comparative study among 864 reproductive age women selected using multistage sampling. Using a structured interviewer-administered questionnaire, we collected data on respondent's socio-demographic characteristics and IPTp uptake. Uptake was adjudged adequate if ≥3 doses were taken, otherwise inadequate. We estimated the proportion of women with adequate IPTp uptake and determined the factors associated with adequate uptake in rural and urban areas using chi square and multiple logistic regression at 5% level of significance. RESULTS: The mean ages of respondents in the urban and rural areas were 28.5±4.6 and 27.4±5.0 years respectively. Adequate IPTp uptake was 82.5% and 60.8% in the urban and rural respectively (p<0.001). In the urban area, women whose husbands had attained ≥ secondary education (aOR:2.9; 95%CI:1.2-7.4; p = 0.02) and those who paid for sulfadoxine/pyrimethamime (aOR:0.2; 95%CI: 0.1-0.6; p = 0.01) were 2.9 times more likely and 5 times less likely to take adequate IPTp respectively compared to respondents whose husbands had attained ≤ primary education and those who had sulfadoxine/pyrimethamine free. In the rural area, women who had attended ANC <4 times (aOR:0.4; 95%CI: 0.3-0.7; p<0.001) were 2.5 times less likely to take adequate IPTp compared to women that had attended ANC ≥4 times. CONCLUSION: Uptake of IPTp was more in the urban than rural areas of Ebonyi State. Interventions that reinforce the importance of health professionals carrying out actions aimed at pregnant women and their partners (spousal) in order to guide them on preventive actions against malaria and other diseases are recommended in Ebonyi State.

Physical inactivity and perceived environmental factors: a cross-sectional study among civil servants in Abia State, Southeastern Nigeria.

Introduction: physical inactivity has been identified as the fourth leading risk factor for global mortality due to non-communicable diseases. Prevalence rates of 91.0% and 62.2%, have been documented among civil servants in the northern and southern parts of Nigeria, respectively. There is a paucity of data regarding the relationship between physical inactivity and environmental factors among civil servants in the State. This study assessed the prevalence and perceived environmental factors associated with physical inactivity among civil servants in Abia State Nigeria. Methods: we conducted a cross-sectional study in which we recruited 440 civil servants using a multistage sampling technique. We used an interviewer-administered structured questionnaire to collect data on sociodemographic, physical activity, and neighbourhood environmental attributes. Descriptive, bivariate and multivariate analysis were done. The level of significance was set at 5%. Results: the mean age of the respondents was 39.0±9.2 years, and 61% were females. The prevalence of physical inactivity was 48.4% (95%CI: 43.7%-53.2%). The putative environmental factors included perceptions of low residential density areas, perceived absence of neighbourhood sidewalks, perceived unavailability of bicycling facilities and the perception of an unsafe neighbourhood due to night crimes. The predictor of physical inactivity was the perceived absence of neighbourhood sidewalks (aOR=2.02, 95%CI: 1.10-3.73). Conclusion: in this study, physical inactivity is prevalent among civil servants in Abia State. The need for the stakeholders in collaboration with the Ministry of Environment to focus on the provision of sidewalk facilities, layout of residential areas and limit security risks in the State to enhance physical activity is highlighted.

Determinants of male involvement in family planning services in Abia State, Southeast Nigeria.

BACKGROUND: Male involvement in family planning (FP) remains low in male-dominant communities. Family planning contributes to the regulation of fertility and population growth in Nigeria. Increasing male involvement in family planning services is crucial in reducing maternal morbidity and mortality in patriarchal societies such as Nigeria. This study identified the determinants of male involvement in family planning services in Abia State, Nigeria. METHODS: This was a cross-sectional study conducted in twelve communities of Abia State, Nigeria. A total of 588 married men who met the eligibility criteria were recruited using a multistage sampling technique. An interviewer-administered semi-structured questionnaire was used to collect data on the variables. Univariate, bivariate and multivariate analysis was done. The level of significance was set at 5%. RESULTS: The overall level of active male involvement in family planning services was 55.1% (95% CI:51.0-59.2%). The mean age of the respondents was 42.4 ± 8.0 years. Access to television (aOR = 1.58, 95% CI: 1.05-2.39), spouse employment status (aOR = 2.02, 95% CI: 1.33-2.06), joint decision-making (aOR = 1.66, 95% CI: 1.05-2.62), and accompanying spouse to the FP clinic (aOR = 3.15, 95% CI: 2.16-4.62) were determinants of active male involvement. CONCLUSION: At least, one out of every two men was actively involved in family planning services. This was determined by access to television, employment status of spouse, joint decision-making, and accompanying spouse to the FP clinic. There is a need to focus on the identified factors in order to further improve the active involvement of men in FP services.
