Evaluation of Molecular Point-of-care Xpert® Xpress SARS-CoV-2 Detection Implementation in Resource-limited Settings

Study Overview
=================
Brief Summary
-----------------
This study is envisaged to evaluate the diagnostic accuracy and effectiveness of POC viral load (VL) assay in improving the availability of SARS-CoV-2 detection for COVID-19 patient management in decentralized healthcare facilities of resource-constrained settings in Tanzania, DR Congo and Burkina Faso.

Detailed Description
-----------------
Project Title: Evaluation of molecular point-of-care Xpert® Xpress SARS-CoV-2 detection implementation in resource limited settings (RIA2020EF-2990) - EXPERT-CoV-2 Principal Investigator: Dr Daniel T. R Minja, NIMR- Tanga Centre, Korogwe Research Station, Tanzania Collaborating Partners: University of Kinshasa, DR Congo, Research Institute for Health Sciences, Burkina Faso, University of Copenhagen, Denmark, Univesity of Antwerp, Belgium, University of valencia, Spain Background. Rapid diagnostic tests of individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are the cornerstone to implement early case detection and management to control the spread of the deadly virus. RT-PCR is the gold standard for detection of SARS-CoV-2 but its availability and userability is impeded by fragmented laboratory infrastructure in LMICs and even when available it's only found in reference labs. Recent development of the Gene Expert molecular Point-of-Care (POC) (Xpert® Xpress SARS-CoV-2/Flu/RSV test , Cepheid Sunnyvale, CA) for SARS-CoV-2 testing in the clinics with results delivery within hours of sample collection has been vital in resolving the turnaround time (TAT). GeneXpert have been widely rolled out within national tuberculosis (TB) and HIV programmes across the Africa. However, evaluation of its diagnostic accuracy and the feasibility of its integration into the TB/HIV programme has not been evaluated in resource-constrained settings. Study objective. This study is envisaged to evaluate the diagnostic accuracy and effectiveness of POC viral load (VL) assay in improving the availability of SARS-CoV-2 detection for COVID-19 patient management in decentralized healthcare facilities of resource-constrained settings in Tanzania, DR Congo and Burkina Faso. Relevance. The rapid spread of SAR-CoV-2 necessitates an urgent improvement in testing capacity at decentralized health facilities in the region. Therefore, a quick evaluation and deployment of this tool will contribute toward controlling the transmission of SARS-CoV-2 in the population. This project (RIA2020EF-2990) is part of the EDCTP2 programme supported by the European Union.
