Article Synopsis
  • In Senegal, molecular diagnosis for COVID-19 was effective, but genomic surveillance in the public sector was limited.
  • The study analyzed 8,207 samples from travelers and symptomatic patients between July 2020 and December 2021, identifying a significant number of SARS-CoV-2 variants through whole-genome sequencing.
  • Results showed that 20A and 20B variants circulated in 2020, while Delta variants were predominant in 2021, highlighting the global trend in viral diversity during the pandemic.

The eradication of neonatal Group B (GBS) infections, considered as a major public health priority, necessarily requires a mastery of the data on vaginal carriage in pregnant women. The aims of this study were to determine the prevalence of vaginal carriage of GBS in pregnant women, antibiotic susceptibility, and associated risk factors. This was a cross-sectional, descriptive study conducted over a period of 9 months (July 2020 to March 2021) in pregnant women between 34 and 38 weeks of gestation (WG) followed at the Nabil Choucair health center in Dakar.

Introduction: early infant diagnosis (EID) is crucial in the prevention of mother to child transmission (PMTCT) of human immunodeficiency virus (HIV) and is an essential component for the elimination of HIV. EID can be strengthened in resource-limited countries by the introduction and the roll out of real-time polymerase chain reaction (PCR) technologies via point-of-care (POC) devices which improves treatment in remote areas and reduces turnaround time for clinicians and patients to receive results and linkage to care. The objective of this study was to evaluate the performance of Xpert® HIV-1 Qual Assay (Cepheid) and m-PIMA™ HIV 1/2 Detect (ABBOTT) for EID of HIV-1 and HIV-2.

Article Synopsis
  • Hepatitis B virus (HBV) is often found in resource-limited countries, which struggle with timely diagnosis and treatment due to a lack of technical facilities.
  • The study evaluated the effectiveness of using dried blood spots (DBS) for detecting and quantifying HBsAg in subjects, showing promising results with high sensitivity and specificity in tests.
  • The findings indicate that DBSs are a feasible and effective tool for managing HBV infection, particularly in areas with limited healthcare resources.

Introduction: While acute respiratory tract infections are the main cause of paediatric mortality and morbidity worldwide, pathogen patterns shift due to factors such as hygiene, vaccinations, and antibiotic resistance. Knowledge about current cause of respiratory infections is lacking, particularly in low- and middle-income countries. The aim of this study was to identity the various respiratory pathogens causing acute respiratory tract infections in children below 5 years of age visiting a sub-urban primary care clinic in Senegal.

Acute respiratory infections (ARIs) are the leading cause of infectious disease-related morbidity, hospitalization, and morbidity among children worldwide. This study aimed to assess the viral and bacterial causes of ARI morbidity and mortality in children under 5 years in Senegal. Nasopharyngeal samples were collected from children under 5 years who had ARI.
