Noroviruses are the second leading cause of death in children under the age of 5 years old. They are responsible for 200 million cases of diarrhoea and 50,000 deaths in children through the word, mainly in low-income countries. The objective of this review was to assess how the prevalence and genetic diversity of noroviruses have been affected by the introduction of rotavirus vaccines in Africa.

OBI represents a risk factor for the development of cirrhosis and hepatocellular carcinoma (HCC). OBI could be due to mutant viruses undetectable by HBsAg assays or a strong suppression of viral replication and gene expression under the pression of the host immune system.

The aim of the present study was to determine the frequencies of HLA-DRB1*11 and HLA-DRB1*12 allele polymorphisms and their associations with COVID-19.
Methods: In this cross-sectional study, 198 subjects were enrolled, including 150 COVID-19 positive cases and 48 subjects who tested negative for COVID-19.
Background: Hepatitis B Virus (HBV) infection affect all social strata of humanity and in the absence of any management, this infection has a different outcome from one infected person to another. This suggests that there are specific individual factors that influence the outcome of the pathology. Sex, immunogenetics and age of contraction of the virus have been cited as factors that influence the evolution of the pathology.

Materials And Methods: Ten (10) SARS-CoV-2 serological rapid diagnostic tests (RDTs) for SARS-CoV-2 IgG/IgM were evaluated with two (2) groups of plasma tested positive for one and negative for the other with the WANTAI SARS-CoV-2 Ab ELISA. The diagnostic performance of the SARS-CoV-2 serological RDTs and their agreement with the reference test were calculated with their 95% confidence intervals.
Introduction: Genital human papillomavirus (HPV) infection is widespread among sexually active individuals. Several factors may contribute to increased risk of infection in pregnant women. The objective of this study was to determine the high-risk (HR-HPV) and low-risk (LR-HPV) oncogenic HPV genotypes among pregnant women in Ouagadougou.

The HPC2/ELAC2 gene has been identified by linkage analysis in familial prostate cancer patients in the United States but has never been studied in Burkina Faso. The objective of the present study was to analyze the carriage of the C650T (Ser217Leu) and G1621A (Ala541Thr) mutations of the ELAC2 gene and the risk factors in prostate cancer patients in Burkina Faso.

Background And Objectives: Dengue fever (DF), an emerging and re-emerging viral disease, is a major public health problem. The aim of this study was to investigate the influence of genes polymorphism and genotypes in susceptibility to dengue virus infection and disease severity in a population from Burkina Faso through a case-control study.
Methods: genes determination was performed using PCR-SSP in 50 patients infected by dengue virus (DENV) and 54 Healthy controls (HC) subjects who had never been infected.
Breast cancer is the leading cause of death among women in both developed and developing countries. It is multifactorial, including genetic predispositions such as oncogenic mutations on and 2 genes. The objectives of the present study were to identify oncogenic mutations in exon 11 of the gene and to determine the risk factors for breast cancer among women population in Burkina Faso.

Background: In resource-limited countries, ABO, HLA, MNS, Kells, and hemoglobin electrophoresis are classic tests for the resolution of paternity disputes due to their affordable cost. The limitations of these tests in cases of disputed paternity require the use of Short Tandem Repeats (STR) for their certification. This study aimed to determine the biological fathers of children using ABO-rhesus/hemoglobin electrophoresis and STR assays in Burkina Faso, West Africa.

Background: Glutathione S-transferases play a key role in the detoxification of persistent oxidative stress products which are one of several risks factors that may be associated with many types of disease processes such as cancer, diabetes, and hypertension. In the present study, we characterize the null genotypes of GSTM1 and GSTT1 in order to investigate the association between them and the risk of developing essential hypertension.
Methods: We conducted a case-control study in Burkina Faso, including 245 subjects with essential hypertension as case and 269 control subjects with normal blood pressure.
