Rapid Global Spread of Covid Variant JN.1: What You Need to Know

The JN.1 sub-variant of the Omicron strain of coronavirus has been classified as a "variant of interest" by the World Health Organization due to its rapid global spread. Although the risk to the public is currently low and current vaccines still offer protection, the WHO warns of a potential increase in Covid-19 and other infections this winter. JN.1 is currently the fastest-growing variant in the United States and is spreading quickly in many parts of the world. It has an additional mutation in the spike protein compared to its predecessor, and more studies are needed to determine its impact on health and vaccine effectiveness. The WHO advises following preventive measures such as wearing masks, practicing good hygiene, and getting vaccinated.
