Clinical symptoms and faecal shedding of SARS-CoV-2 RNA among hospitalized COVID-19 patients: Implication for transmission.

SARS-CoV-2 shedding in human stool has been suggested as a probable route for faeco-oral transmission of the virus due to the availing evidence on the infectivity and pathogenicity of similar highly infectious respiratory viruses. Determining association of SARS-CoV-2 shedding in stools and presenting clinical status might be useful for prediction of the viral transmission spectrum and disease outcome. This study involved a descriptive cross-sectional survey of 91 consenting hospitalized, confirmed COVID-19 patients in Infectious Disease Isolation Centre, Oyo State, Nigeria.

Methods: A cross-sectional study of 86 adult patients hospitalized with COVID-19 between March and November 2020.

A multi-country phase 2 study to evaluate the suitcase lab for rapid detection of SARS-CoV-2 in seven Sub-Saharan African countries: Lessons from the field.

Background: The COVID-19 pandemic led to severe health systems collapse, as well as logistics and supply delivery shortages across sectors. Delivery of PCR related healthcare supplies continue to be hindered. There is the need for a rapid and accessible SARS-CoV-2 molecular detection method in low resource settings.

Seroprevalence of anti-SARS-CoV-2 specific antibodies in vaccinated and vaccine naïve adult Nigerians.

Background: Reports on the evaluation of immune responses to different COVID-19 vaccines are limited. Similarly, effects of age and gender have not been well explored as variables that could impact on the vaccine-induced antibody response. Therefore, seroprevalence of anti-SARS-CoV-2 specific antibodies in vaccinated and vaccine naïve adult Nigerians was determined in this study.

A randomized, open-label trial of combined nitazoxanide and atazanavir/ritonavir for mild to moderate COVID-19.

Background: The nitazoxanide plus atazanavir/ritonavir for COVID-19 (NACOVID) trial investigated the efficacy and safety of repurposed nitazoxanide combined with atazanavir/ritonavir for COVID-19.

Methods: This is a pilot, randomized, open-label multicenter trial conducted in Nigeria. Mild to moderate COVID-19 patients were randomly assigned to receive standard of care (SoC) or SoC plus a 14-day course of nitazoxanide (1,000 mg b.

Prevalence of hepatitis B virus core antibodies among blood donors in Nigeria: Implications for blood safety.

Background: Anti-hepatitis B core antibody (anti-HBc) testing improves transfusion safety by detecting past and current hepatitis B virus (HBV) infection while detecting hepatitis B surface antigen (HBsAg) in serology-negative HBV infection. However, occult HBV infection (OBI) (serum or liver HBV DNA-positive but HBsAg-negative) remains unaddressed among replacement blood donors - family members or friends who donate to replace blood transfused to a relative.

Objective: This study assessed risk factors for a positive anti-HBc test among donors with OBI and determined the anti-HBc-positive status of replacement donors.

The African Female Breast Cancer Epidemiology Study Protocol.

Breast cancer is now the commonest cancer in most sub-Saharan African countries. Few studies of the epidemiology and genomics of breast cancer and its molecular subtypes in these countries have been done. The African Female Breast Cancer Epidemiology (AFBRECANE) study, a part of the Human Heredity and Health in Africa (H3Africa) initiative, is designed to study the genomics and epidemiology of breast cancer and its molecular subtypes in Nigerian women.

Assessment of hepatitis B surface antigen negative blood units for HBV DNA among replacement blood donors in a hospital based blood bank in Nigeria.

Background: Hepatitis B virus infection is one of the greatest threats to blood safety all over the world. The laboratory algorithm based on only the detection of hepatitis B surface antigen (HBsAg) leaves a gap for infected HBsAg negative donors to donate blood during the "window period" (WP) and late stages of infection.

Objective: To estimate the frequency of the presence of HBV deoxyribonucleic acid (DNA) in HBsAg negative blood units screened using two different assays for HBsAg in a high endemic region.

Multiple expansions of globally uncommon SARS-CoV-2 lineages in Nigeria.

Disparities in SARS-CoV-2 genomic surveillance have limited our understanding of the viral population dynamics and may delay identification of globally important variants. Despite being the most populated country in Africa, Nigeria has remained critically under sampled. Here, we report sequences from 378 SARS-CoV-2 isolates collected in Oyo State, Nigeria between July 2020 and August 2021.

Changes in Selected Renal Function Parameters of Newly Admitted COVID-19 Patients from One Infectious Diseases Center in Ibadan, Nigeria: Indication for Immunopathology.

COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) enters the host cells through attachment to the Angiotensin Converting Enzyme-2 receptors (ACE-2) on the host cells. ACE-2 is known to affect renal functions, vasoconstriction and fluid homeostasis. Thus, the impact of SARS-CoV-2 infection on renal functional parameters is worth investigating.

Qualitative exploration of health system response to COVID-19 pandemic applying the WHO health systems framework: Case study of a Nigerian state.

Pandemics can result in significantly high rates of morbidity and mortality with higher impact in Lower- and Middle-Income Countries like Nigeria. Health systems have an important role in a multi-sector response to pandemics, as there are already concerns that COVID-19 will significantly divert limited health care resources. This study appraised the readiness and resilience of the Nigerian health system to the COVID-19 pandemic, using Oyo State, southwest Nigeria, as a case study.

Frequency of Hepatitis B Virus Envelope Antigen and Antibodies Among Chronic Carriers in Ibadan, Nigeria.

Hepatitis B virus (HBV) infection is a major health challenge in sub-Saharan Africa with a prevalence rate of >7%. It is an important clinical problem due to its potential adverse sequelae, including hepatocellular carcinoma. The additional challenge of its associated chronic infection makes its prevention difficult despite the widely available vaccine.

Hepatitis E Virus Infection among Asymptomatic Pregnant Women at the University College Hospital, Ibadan.

Introduction: The high mortality associated with fulminant Hepatitis E infection in pregnancy justifies the need to assess the epidemiologic proportion of this underestimated virus.

Objectives: This study aimed to determine the burden of HEV infection among pregnant women attending antenatal Clinic in Ibadan.

Methodology: HEV IgG and IgM serological surveys were carried out among 230 pregnant women attending antenatal clinic in Ibadan, Nigeria.

Coincident rapid expansion of two SARS-CoV-2 lineages with enhanced infectivity in Nigeria.

The emergence of new SARS-CoV-2 variants with enhanced transmissibility or decreased susceptibility to immune responses is a major threat to global efforts to end the coronavirus disease 2019 (COVID-19) pandemic. Disparities in viral genomic surveillance capabilities and efforts have resulted in gaps in our understanding of the viral population dynamics across the globe. Nigeria, despite having the largest population of any nation in Africa, has had relatively little SARS-CoV-2 sequence data made publicly available.
