The emergence of the XEC variant amid declining COVID-19 rates poses potential risks as the cold and flu season begins.

The XEC variant is spreading across countries, showing mild symptoms but greater ease of transmission compared to earlier COVID strains.

The new COVID subvariant XEC is gaining traction and could soon become prevalent in the U.S. as it spreads globally.

At-home COVID-19 antigen tests remain effective against circulating variants, particularly Omicron, although the immune response may impact testing accuracy.

New mRNA vaccines targeting Omicron KP.2 have been approved to enhance protection against Covid-19 amidst rising infection rates.

Omicron is a highly mutated variant of the coronavirus that emerged in South Africa and spread rapidly.

Omicron challenges assumptions virologists had before the pandemic and has become adept at evading immunity.

Researchers are trying to make sense of the past two years and prepare for the future, but warn that the virus still has the capacity to surprise.
