Tracking SARS-CoV-2 variants in the Americas

Coordinated by PAHO and comprised of laboratories from 24 countries in the Region, the COVID-19 Genomic Surveillance Regional Network (COVIGEN) monitors the virus that causes COVID-19 to detect any change in its sequence that may influence its ability to spread, disease severity, vaccine effectiveness, treatments, diagnostics, or other public health and social measures. How does the network work? What is the current distribution of the variants of concern? And why is this network important to help end the pandemic and prepare for the future?
