Clinical Trial Summary

The main objective of this research is to identify and characterize the different molecular variants of SARS-CoV-2, emerging and / or circulating in several countries of Sub-Saharan Africa (Burkina Faso, Côte d'Ivoire, Gabon, Mali, Chad and Republic of Congo) and determine their role in the evolution of the pandemic.

Description:

The main objective of this research is to identify and characterize the different molecular variants of SARS-CoV-2, emerging and / or circulating in several countries of Sub-Saharan Africa (Burkina Faso, Côte d'Ivoire, Gabon, Mali, Chad and Republic of Congo) and determine their role in the evolution of the pandemic. The research will combine retrospective and prospective approaches to determine the evolutionary dynamics of the virus since the start of the pandemic. It is planned to sequence the entire Spike protein gene for 1550 viruses and make 300 entire genomes. This work will be supplemented by antibody seroneutralization and respiratory transcriptomics tests, in order to estimate the immuno-virological response of the COVID-19 disease associated with the identified SARS-CoV-2 variants.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of SARS-CoV-2 sequences generated partially and in whole genome	This outcome represent our main gaol and will include sequences that were partially generated in the Spike proteine and full genomes as well. Our current target is 1550 sequences.	Through study completion, an average of 1 year.
Secondary	Number of individuals tested positive for COVID-19	This outcome will be focused on the number of persons that will be tested positive for COVID-19 throughout the study, using SARS-CoV-2 rapid antigen tests. We planned to screen 12000 individuals overall in the six participating countries.	Up to six months
Secondary	Number of new SARS-CoV-2 variants identify	This outcome represents the number of new viruses that are identified at the end of the study and have not been reported previously.	Through study completion, an average of 1 year.
