Performance evaluation of Sars-CoV-2 rapid diagnostic tests in Nigeria
The COVID-19 pandemic challenged health systems globally. Reverse transcription polymerase chain reaction (RT-PCR) is the gold standard for detecting the presence of SARS-CoV-2 in clinical samples. Rapid diagnostic test (RDT) kits for COVID-19 have been widely used in Nigeria. This has greatly improved test turnover rates and significantly decreased the high technical demands of RT-PCR. However, there is currently no nationally representative eva…
Seroprevalence of Sars-CoV-2 in four states of Nigeria in October 2020
The observed epidemiology of SARS-CoV-2 in sub-Saharan Africa has varied greatly from that in Europe and the United States, with much lower reported incidence. Population-based studies are needed to estimate true cumulative incidence of SARS-CoV-2 to inform public health interventions. This study estimated SARS-CoV-2 seroprevalence in four selected states in Nigeria in October 2020. We implemented a two-stage cluster sample household survey in fo…
Covid-19 mortality rate and its associated factors during the first and second waves in Nigeria
COVID-19 mortality rate has not been formally assessed in Nigeria. Thus, we aimed to address this gap and identify associated mortality risk factors during the first and second waves in Nigeria. This was a retrospective analysis of national surveillance data from all 37 States in Nigeria between February 27, 2020, and April 3, 2021. The outcome variable was mortality amongst persons who tested positive for SARS-CoV-2 by Reverse-Transcriptase Poly…
Covid-19 vaccine effectiveness studies in Nigeria
The “lickety–split” development of COVID-19 vaccines 326 days from when the SARS-COV-2 virus was first sequenced is indeed one of the public health successes of the 21st century. Particularly because an 18-month target was initially considered reasonable, and having achieved this success, a “moonshot” goal to ensure that a vaccine is available within 100 days [...]
The HIV Epidemic in South Africa
South Africa has the largest number of people living with HIV worldwide. South Africa has implemented five population-based HIV prevalence surveys since 2002 aimed at understanding the dynamics and the trends of the epidemic. This paper presents key findings from the fifth HIV prevalence, incidence, and behaviour survey conducted in 2017 following policy, programme, and epidemic change since the prior survey was conducted in 2012. A cross-section…
Is There Risk Compensation among HIV Infected Youth and Adults 15 Years and Older on Antiretroviral Treatment in South Africa? Findings from the 2017 National HIV Prevalence, Incidence, Behaviour and …
In this paper, risk compensation among individuals on antiretroviral therapy (ART), using the 2017 South African national survey on HIV, is explored. A multi-stage stratified cluster random sampling approach was used to realize 11,130 participants 15 years and older. Logistic regression analysis assessed the association between multiple sexual partners, condom use at last sexual encounter, consistency of condom usage and potential explanatory var…
Epidemiological comparison of the first and second waves of the Covid-19 pandemic in Nigeria, February 2020–April 2021
BACKGROUND: With reports of surges in COVID-19 case numbers across over 50 countries, country-level epidemiological analysis is required to inform context-appropriate response strategies for containment and mitigation of the outbreak. We aimed to compare the epidemiological features of the first and second waves of COVID-19 in Nigeria. METHODS: We conducted a retrospective analysis of the Surveillance Outbreak Response Management and Analysis Sys…
Nigeria’s public health response to the Covid-19 pandemic
The novel coronavirus disease 2019, COVID-19, which is caused by severe acute respiratory syndrome \nvirus 2 (SARS-CoV-2) [1] was first reported in December 2019 by Chinese Health Authorities following an outbreak of pneumonia of unknown origin in Wuhan, Hubei Province [2,3]. SARS-CoV-2 is \nlikely of zoonotic origin, similar to SARS and Middle East Respiratory Syndrome (MERS), and transmitted between humans through respiratory droplets and fomit…
Towards achieving the 90–90–90 HIV targets
South Africa appears to be on track to achieve the first 90 indicator by 2020. However, it is behind on the second 90 indicator with ART coverage that was ~ 20-percentage points below the target among people who knew their HIV status, this indicates deficiencies around linkage to and retention on ART. Overall viral suppression among those on ART is approaching the target at 87.4%, but this must be interpreted in the context of low reported ART co…
Socioeconomic status and risk of cardiovascular disease in 20 low-income, middle-income, and high-income countries
Background Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education a…

Training Medical Students in the Community - Memoirs and Reflections of the University of Transkei Medical School
Not long after its inception, the undergraduate medical program at the University of Transkei (UNITRA) departed from the traditional hospicentric medical education approach to one tailored around a Community-Based Medical Education (CBME) curriculum adopting the Problem-based Learning (PBL) pedagogy. This article reflects on the experiences of the faculty in establishing and implementing CBME, exploring what it has meant to train medical students…
