These mutations are raising concerns among health officials due to their potential impact on transmissibility and immune evasion.
Unlike previous variants that emerged from a clear lineage, JN.1 has a ample number of genetic differences from its parent strain, BA.2.86. This makes it more difficult to predict its behavior and necessitates careful monitoring.
Spread and Prevalence
JN.1 was first detected in August 2023. As then, its prevalence has been steadily increasing. Recent data indicates a rapid rise in cases,particularly in the United states and France.
- United States: As of mid-December 2023,JN.1 is estimated to be the most dominant variant in the US, accounting for over 40% of sequenced cases. CDC Data
- France: A new wave of COVID-19 is being observed in Paris and the Île
