New COVID Variant JN.1 Emerges as Dominant Strain in the US.

Trending Now

A new coronavirus subvariant, JN.1, is rapidly spreading across the United States, now accounting for nearly half of the country's recent COVID-19 cases, as reported by the US Centers for Disease Control and Prevention (CDC) according to New York Times.

JN.1 has become the fastest-growing and dominant variant in the US, responsible for over 44 percent of new infections, a significant increase from the previously reported 21.4 percent.

The CDC's data indicates that JN.1 is particularly prevalent in the Northeast regions, including New Jersey and New York, where it comprises nearly 57 percent of cases.

This variant is closely related to the BA.2.86 variant, which the CDC has been monitoring since August 2023.

JN.1 was first detected in the United States in September 2023.

According to the CDC, JN.1 is likely more transmissible than other variants or better at evading immune responses than other circulating variants.

This development underscores the evolving nature of the COVID-19 virus and the importance of continued vigilance and adaptation in public health strategies.
