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.

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 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.

Effects of an urban sanitation intervention on childhood enteric infection and diarrhea in Maputo, Mozambique: A controlled before-and-after trial.

We conducted a controlled before-and-after trial to evaluate the impact of an onsite urban sanitation intervention on the prevalence of enteric infection, soil transmitted helminth re-infection, and diarrhea among children in Maputo, Mozambique. A non-governmental organization replaced existing poor-quality latrines with pour-flush toilets with septic tanks serving household clusters. We enrolled children aged 1-48 months at baseline and measured outcomes before and 12 and 24 months after the intervention, with concurrent measurement among children in a comparable control arm. Despite nearly exclusive use, we found no evidence that intervention affected the prevalence of any measured outcome after 12 or 24 months of exposure. Among children born into study sites after intervention, we observed a reduced prevalence of Trichuris and Shigella infection relative to the same age group at baseline (<2 years old). Protection from birth may be important to reduce exposure to and infection with enteric pathogens in this setting.

Profile of people seeking health services during Pope Francis' visit to Mozambique, 2019.

Pope Francis visited Mozambique from September 4-6, 2019. During the visit, a real-time surveillance system for mass gathering events was implemented in all places where people gathered in Maputo City for early detection of possible outbreaks and other health-related events. The system was implemented at four sites were mass gathering events occurred over the three-day visit. Data were collected by administering a simple questionnaire on a tablet, which collected information about sociodemographics, syndromic diagnoses, and outcomes of the patients that sought medical care. Additionally, a descriptive epidemiological assessment was performed during the event. A total of 150 individuals were attended at the designated places during the event. Of these, 56.7% were female and 90.7% aged > 15 years. The majority of the patients (74.7%) sought care on the third day of the event, which was held at the Zimpeto National Stadium. The most common diagnoses were hypertension (20.7%), hypothermia (15.3%), and headache (11.3%). Almost all cases (95.0%) were discharged, (4.0%) cases were transferred and (1.0%) case resulted in death on the way to the health facility. The surveillance system strategy developed to detect real-time public health events during the Pope?s visit was successfully implemented. No outbreak was identified during the event.

Epidemiological profile of health consultations during the Mozambique 9th National Cultural Festival, August 2016.

INTRODUCTION: The use of mass gatherings as spaces to practice health surveillance has been growing in recent years. In Mozambique, the 9th National Festival of Culture in 2016 was selected for this practice. A specific public health surveillance system to facilitate rapid detection of outbreaks and other health-related events was implemented for this event with real time data collection and analysis. METHODS: A descriptive epidemiological evaluation of all the health consultations that occurred in fixed posts prepared for the event was conducted. The data were collected through electronic mobile system (tablets) in real time, with the aid of a form designed for this purpose and sent directly to the incident command system (ICS). RESULTS: During the event, a total of 355 patients were assisted, 52.3% were female, 87.0% were from Beira city and the artists were the group that most frequently sought health care at 59.4%. The largest number of visits took place on the third day (36.4%). People over 45 years of age were the age group that most frequently sought health care (30.8%). The main provisional diagnoses of those who were attended to during the festival was arterial hypertension (20.3%), followed by febrile syndrome (19.0%), with falls being the most frequent causes of trauma during the festival (60.0%). CONCLUSION: The system of monitoring in real time using mobile technologies proved to be efficient for the monitoring of the main health events during the mass gatherings. This profile of health consultations encourages the health sector to plan strategies and actions geared to the reality of care for this type of event.
