Genomic surveillance of SARS-CoV-2 in the Republic of Congo
With the first cases reported on March 14, 2020 (Ntoumi and Velavan, 2020), the Republic of Congo reported a total of 7794 cases with 117 deaths as of January 25, 2021, with transmission driven by the community (WHO, 2021).Could the D614G substitution in the SARS-CoV-2 spike (S) protein be associated with higher COVID-19 mortality?
The increasing number of deaths due to the COVID-19 pandemic has raised serious global concerns. Increased testing capacity and ample intensive care availability could explain lower mortality in some countries compared to others. Nevertheless, it is also plausible that the SARS-CoV-2 mutations giving rise to different phylogenetic clades are responsible for the apparent death rate disparities around the world. Current research literature linking the genetic make-up of SARS-CoV-2 with fatalities is lacking.
