COVID-19: Data

Variants

JN.1 Variant

The JN.1 variant has been detected in New York City. JN.1 is closely related to BA.2.86, which has been spreading in New York City since August 2023.

According to the CDC, existing vaccines, tests and treatments still work well against JN.1. When cases rise and some new variants emerge, precautions are increasingly important, especially for New Yorkers who are older or have underlying health conditions. Masking, testing and staying home when sick can reduce the spread of COVID-19. Antibodies from vaccination and immunity from prior infections can also make us less likely to get sick. Antiviral medicines like Paxlovid can treat infection.

Everyone should continue to stay up to date on COVID-19 vaccinations, get tested if they have symptoms or have been exposed, and wear a high-quality mask when they are sick, following an exposure or when COVID-19 levels increase.

The data on this page show how variants of the virus that causes COVID-19 are spreading in NYC. Variants are versions of the virus with certain sets of mutations. Some variants may result in a COVID-19 infection that is easier to spread, more severe or able to avoid antibodies from vaccines or previous infections.
