Delayed SARS-COV-2 clearance in infected persons in Ghana.

Objective: This study aimed to determine the duration of SARS-CoV-2 clearance in persons in Ghana. The research question was whether the duration of virus clearance in Ghana matched the 14 days recommended by the World Health Organization (WHO); this had direct implications for transmission, which was key in managing the COVID-19 pandemic.

Design: This was a retrospective analytical study.

Healthcare Provider Perspectives on HIV Cure Research in Ghana.

Introduction: Antiretroviral therapy (ART) has reduced mortality and improved life expectancy among HIV patients but does not provide a cure. Patients must remain on lifelong medications and deal with drug resistance and side effects. This underscores the need for HIV cure research.

SARS-CoV-2 Molecular Evolutionary Dynamics in the Greater Accra Region, Ghana.

To assess dynamics of SARS-CoV-2 in Greater Accra Region, Ghana, we analyzed SARS-CoV-2 genomic sequences from persons in the community and returning from international travel. The Accra Metropolitan District was a major origin of virus spread to other districts and should be a primary focus for interventions against future infectious disease outbreaks.

SARS-CoV-2 infections among asymptomatic individuals contributed to COVID-19 cases: A cross-sectional study among prospective air travelers from Ghana.

Background: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by asymptomatic individuals has been reported since the early stages of the coronavirus disease 2019 (COVID-19) outbreak in various parts of the world. However, there are limited data regarding SARS-CoV-2 among asymptomatic individuals in Ghana. The aim of the study was to use test data of prospective travelers from Ghana as a proxy to estimate the contribution of asymptomatic cases to the spread of COVID-19.

Unwillingness of patients in Ghana to interrupt antiretroviral therapy for HIV cure research.

Objectives: Though antiretroviral therapy (ART) has reduced HIV infection into a manageable chronic disease, it does not provide for a cure. HIV cure trials may carry risks for patients who are generally doing well on ART, making it imperative that their input is sought as various types of cure methods and trials are designed. Few studies have sought the views of African patients on HIV cure studies.

Overexpression of the nucleocapsid protein of Middle East respiratory syndrome coronavirus up-regulates CXCL10.

Middle East respiratory syndrome coronavirus (MERS-CoV) causes respiratory diseases in humans and has a high mortality rate. During infection, MERS-CoV regulates several host cellular processes including antiviral response genes. In order to determine if the nucleocapsid protein of MERS-CoV (MERS-N) plays a role in viral-host interactions, a murine monoclonal antibody was generated so as to allow detection of the protein in infected cells as well as in overexpression system.

A cross-clade H5N1 influenza A virus neutralizing monoclonal antibody binds to a novel epitope within the vestigial esterase domain of hemagglutinin.

The sporadic outbreaks of highly pathogenic H5N1 avian influenza virus have raised public health concerns. Monoclonal antibodies (MAbs) against hemagglutinin (HA) have been increasingly used successfully for therapeutic purposes. Previously, MAb 9F4, generated against clade 1 H5N1 HA, was observed to have cross-clade neutralizing efficacy and inhibited viral entry by preventing the pH-mediated conformational change of HA.
