Comparative evaluation of RT-PCR and antigen-based rapid diagnostic tests (Ag-RDTs) for SARS-CoV-2 detection: performance, variant specificity, and clinical implications.

The COVID-19 pandemic has highlighted the critical need for accurate and efficient diagnostic tools for detecting severe acute respiratory coronavirus 2 (SARS-CoV-2) infections. This study presents a comparison of two diagnostic tests: RT-PCR and antigen detection rapid diagnostic tests (Ag-RDTs). This study focused on their performance, variant specificity, and their clinical implications.

Molecular Epidemiology of SARS-CoV-2 within Accra Metropolis Postlockdown.

Introduction: Currently, sequencing has been the only tool for the identification of circulating severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants. However, it is known to be an expensive and laborious approach involving high technical expertise. Considering the reduced adherence to preventive measures postlockdown in Accra, this study presents an alternative method that leverages polymerase chain reaction (PCR) to identify circulating SARS-CoV-2 variants in the Accra Metropolis postlockdown.

Implementation of Concussion Management Policies in High Schools: The Critical Role of School Nurses.

Evidence-based practices in concussion management (CM) have been codified into legislation. However, legislation is varied, and implementation is narrowly evaluated. School nurses hold a unique position to assess the implementation of health policies.

Seroprevalence and effect of HBV and HCV co-infections on the immuno-virologic responses of adult HIV-infected persons on anti-retroviral therapy.

Chronic hepatitis negatively affects persons living with HIV. While varying in their transmission efficiency, HIV, HBV, and HCV have shared routes of transmission. Available data suggest widely variable rates of HBV and HCV infections in HIV-infected populations across sub-Saharan Africa.
