COVID-19 Subvariant JN.1 Spreads Rapidly, Raises Global Health Concerns

Despite the rapid spread, current tests, treatments, and vaccines are expected to be effective against the new variant.

COVID-19 subvariant JN.1, a descendant of Omicron, is spreading rapidly and is believed to be either more transmissible or better at evading our immune systems, according to the CDC and WHO.
COVID-19 cases attributed to JN.1 have grown by more than 20% in just a month, making it the fastest-spreading variant currently circulating.
COVID-19 hospitalizations and deaths have both climbed recently, with hospitalizations swelling by more than 50%, and deaths rising 25% during the most recent week on record.
COVID-19 tests and treatments are expected to be effective against JN.1, and preliminary research suggests that the latest COVID-19 booster shot also generates antibodies that work against JN.1.
Health authorities worldwide are urging vigilance, increased testing, and adherence to public health measures to minimize transmission of the virus.
