RESUMO
INTRODUCTION: As part of efforts to rapidly identify and care for individuals with COVID-19, trace and quarantine contacts, and monitor disease trends over time, most African countries implemented interventions to strengthen their existing disease surveillance systems. This research describes the strengths, weaknesses and lessons learnt from the COVID-19 surveillance strategies implemented in four African countries to inform the enhancement of surveillance systems for future epidemics on the continent. METHODS: The four countries namely the Democratic Republic of Congo (DRC), Nigeria, Senegal, and Uganda, were selected based on their variability in COVID-19 response and representation of Francophone and Anglophone countries. A mixed-methods observational study was conducted including desk review and key informant interviews, to document best practices, gaps, and innovations in surveillance at the national, sub-national, health facilities, and community levels, and these learnings were synthesized across the countries. RESULTS: Surveillance approaches across countries included - case investigation, contact tracing, community-based, laboratory-based sentinel, serological, telephone hotlines, and genomic sequencing surveillance. As the COVID-19 pandemic progressed, the health systems moved from aggressive testing and contact tracing to detect virus and triage individual contacts into quarantine and confirmed cases, isolation and clinical care. Surveillance, including case definitions, changed from contact tracing of all contacts of confirmed cases to only symptomatic contacts and travelers. All countries reported inadequate staffing, staff capacity gaps and lack of full integration of data sources. All four countries under study improved data management and surveillance capacity by training health workers and increasing resources for laboratories, but the disease burden was under-detected. Decentralizing surveillance to enable swifter implementation of targeted public health measures at the subnational level was a challenge. There were also gaps in genomic and postmortem surveillance including community level sero-prevalence studies, as well as digital technologies to provide more timely and accurate surveillance data. CONCLUSION: All the four countries demonstrated a prompt public health surveillance response and adopted similar approaches to surveillance with some adaptations as the pandemic progresses. There is need for investments to enhance surveillance approaches and systems including decentralizing surveillance to the subnational and community levels, strengthening capabilities for genomic surveillance and use of digital technologies, among others. Investing in health worker capacity, ensuring data quality and availability and improving ability to transmit surveillance data between and across multiple levels of the health care system is also critical. Countries need to take immediate action in strengthening their surveillance systems to better prepare for the next major disease outbreak and pandemic.

BACKGROUND: Globally, infant mortality has declined considerably but has remained unacceptably high in sub-Saharan Africa, especially Nigeria where infant mortality rate is 67/1000 live births. To facilitate infant mortality reduction in Nigeria, an understanding of the synergistic effect of bio-demographic characteristics of mothers known as High Risk Birth Behaviours (HrBBs) is important. We therefore investigated the influence of HrBBs on infant survival in Nigeria. METHODS: This cross-sectional study design utilized data from the 2018 round of Nigerian Demographic Health Survey. The study participants were a representative sample of women of reproductive age (n = 21,350) who had given birth within the 5 years preceding the survey. HrBBs was measured through integration of information on maternal age at child's birth, parity, and preceding birth interval with respect to the most recent child. The HrBBs was categorized as none, single and multiple. Data were analysed using descriptive statistics, Log-rank test and Cox proportional hazard model (α =0.05). RESULTS: The mean age of the women was 29.7 ± 7.2 and 4.1% had experienced infant death. Infant mortality was highest among women with multiple HrBBs (5.1%). Being a male, having small size at birth, failure to receive tetanus injection, non-use of contraceptives and living in the core-north (North West and North East) predisposed children to higher risk of dying before 12 months of age. The hazard ratio of infant mortality was significantly higher among infants of mothers in multiple HrBBs category (aHR = 1.66; CI: 1.33-2.06) compared to their counterparts with no HrBBs. CONCLUSION: Multiple HrBBs increase the chances of dying among infants in Nigeria. Screening women for HrBBs for special health attention during pregnancy, birth and postnatal period will alleviate infant death in Nigeria.

Management of hypertension is challenging in multi-cultural and multi-ethnic sub-Saharan African countries like Nigeria. This diversity calls for multi-dimensional interventional approaches for hypertension control. This study assessed the treatment seeking behaviour and associated factors among adults with high blood pressure from three ethnic groups in Nigeria. A cross-sectional study was conducted among 762 adults with high blood pressure from three purposively selected States representing the three main tribes in Nigeria. Using a multistage stratified sampling technique, five communities were selected from two Local Government Areas (LGAs) stratified into urban and rural LGAs in each State. All consenting respondents in each community were consecutively screened for hypertension and recruited. A pretested interviewer-administered questionnaire was used to obtain information on socio-demographic characteristics, treatment seeking behaviour and factors affecting their choice. Data were summarized using descriptive statistics. Relationship between individual, health-related factors and treatment seeking behaviour, as well as the predictors were assessed using a binary logistic regression. at p<0.05 Participants' mean age was 55.4 ± 16.6 years, 63.0% were females and most were Igbo speaking (39.9%). About half (368, 48.3%) were unaware of their status. Of those aware, most (58.9%) went to hospital upon diagnosis of hypertension while some sought advice from health care professionals (28.5%) mostly Hausas, others either went to chemists (6.2%) or did nothing (5.1%), predominantly Yorubas. Significant predictors of orthodox treatment seeking practices for hypertension were female gender [(AOR = 2.60; 95%CI (1.18-5.71)], availability of medicine and personnel [(AOR = 8.7; 95%CI (4.15-18.3)] and perceived good quality of care [(AOR = 4.88; 95%CI (1.81-13.1)]. Orthodox treatment was the common choice among adults with high blood pressure. To further encourage patronage of orthodox treatment, the health facilities should be adequately equipped with medications and trained personnel to improve the quality of care. Targeted education on continuous practice of orthodox treatment is recommended.
RESUMO
Introduction: the decision of men is pertinent to contraceptive uptake in a patriarchal society like Nigeria. Earlier studies on contraception in Nigeria have focused majorly on women. In this paper, we identified factors influencing contraceptive use, and non-users' perceptions about family planning among Nigerian men. Methods: using data from the 2018 Nigeria Demographic and Health Survey, this retrospective cross-sectional study focused on men aged 15-59 years. Three outcome variables were analysed: modern contraceptive use categorised as non-users or users; perception about contraception captured using two statements- "contraception is woman's business"; "women who use contraception may become promiscuous". Data were analyzed using multivariable logit model with robust standard errors (α= 0.05). Results: mean age of the men was 37.3 years (SD=10.2). Out of 9622 study participants, 71.0% do not use any modern contraceptive method; 19.9% believed that contraception is woman's business while 38.1% believed that women who used contraceptives may become promiscuous. Significant predictors of non-use of contraceptives and perceptions about family planning were older age, low education, Islamic religion, exposure to family planning messages, desire for more children and residence in Northern part of Nigeria. Conclusion: large proportion of contraceptive non-users had negative perceptions. Educational intervention and advocacy among Nigerian men are essential to increase contraceptive uptake.

Introduction: time to clinical recovery from COVID-19 infection and associated factors has not been explored in Nigeria. This study was conducted to assess the predictors and time to recovery from COVID-19 among patients attended to at the treatment centers in Ekiti State, South West. Methods: a facility-based retrospective cohort study was conducted between March 2020 to October 2021. Laboratory confirmed COVID-19 positive test result of 586 patients receiving treatment at the treatment centres in Ekiti were included. Data were extracted from COVID-19 intake forms and medical records of patients. Data were analysed using descriptive statistics and survival analysis methods including Cox proportional hazards regression model. Level of significance was set at 5%. Results: the mean age of the patients was 43.46 (SD 0.74) years. Forty-seven percent (47%) of the patients were aged 25-44 years, fifty-one percent (51%) were males. The median recovery time of COVID-19 patients was 21 days (IQR: 14-23). Being a male-patient (95% CI 20.46-21.54), older age (95% CI 20.14-21.86), not admitted in the hospital (95% CI 22.74-23.26), and associated multiple co-morbidities (95% CI 17.65-28.35) were associated with delayed recovery time. Predictors of recovery time of patients from COVID-19 infection were admission status (aHR: 0.71, 95%CI 0.56-0.88; p=0.002) and symptoms on admission (aHR: 0.81, 95%CI 0.66-0.99; p=0.020). Conclusion: patients with comorbidities, older and those not admitted were more likely to have a delayed clinical recovery from COVID-19. Knowledge of the predictors might help health professionals in risk stratification and better management of patients with COVID-19.

INTRODUCTION: neglected tropical diseases (NTDs) are serious public health problem worldwide. Primary healthcare (PHC) workers are important in the prevention and control of these diseases. Accurate diagnosis and timely reporting are essential for effective public health response. The study assessed the knowledge of PHC workers on NTDs and identified factors influencing its recognition and reporting. METHODS: the study was a hospital based cross-sectional survey. A multistage sampling technique was used to select 327 healthcare workers from sixty-six PHC facilities in Ibadan, Oyo State, Nigeria. A semi-structured, self-administered questionnaire was used to elicit information on respondent´s socio-demographic characteristics, knowledge, recognition and reporting of NTDs. Data analysis were done using independent sample t-test, analysis of variance and logistic regression with p-value set at 0.05. RESULTS: one hundred and eighty seven (57.2%) respondents had good knowledge of NTDs. The NTDs most known were; Schistosomiasis (78%), Rabies (64.5%), and Onchocerciasis (57.2%). Urban healthcare workers had higher knowledge score on NTDs (p= 0.018). Young age (AOR= 3.40, CI= 1.20 -9.63), length of practice (AOR=4.65, CI= 1.20-18.09) and previous training on NTDs (AOR = 7.09, CI= 3.15 - 15.93) significantly predicted NTDs recognition, while availability of reporting forms (AOR= 3.17, CI=1.07 - 9.35), training on disease reporting (AOR= 3.41, CI= 11.17 - 9.92) and feedback on previous diseases reported (AOR= 4.12, CI= 1.32-12.80) were significant predictors of reporting NTDs. CONCLUSION: the healthcare workers knowledge on NTDs was inadequate. Periodic training and continued education on NTDs are recommended. PHC workers also require supportive supervision.

The recent Coronavirus disease (COVID-19) caused by the novel strain of coronavirus (SARS-CoV-2 virus) has become a worldwide public health crisis with associated high mortality rates globally. Human to human transmission of the infection emphasizes the importance of adhering to public and social measure to halt its spread. However, the recent #ENDSARS protests led by angry youths in Nigeria resulted to complete flouting of all WHO guidelines meted to curb the spread of the virus. Given that the nation is the most populous African country with over 50 percent of her population been youths, this situation has huge implications for the country and Africa as a whole. The risk of community transmission occasioned by the protest, coupled with travels and active mobility across countries within the continent increases the risk of community transmission with possible increases in new cases over the next few weeks to months. From the foregoing, it is expedient to increase awareness and enforcement of the use of personal protective equipment especially use of nose masks, face shields and frequent hand washing or sanitizing in public places. These individual-targeted measures will go a long way to curtail the imminent community transmission of COVID-19 across Nigeria. It is therefore recommended that Government and non-governmental agencies across the region actively engage to increase collaborative efforts; screening facilities and access to these services across the country, as well as accentuate regular adherence to preventive measures to the general public.
