KP.3.1.1 first turned the dominant pressure within the two-week interval, beginning on July twenty first and ending on August third.
“The KP.3.1.1 variant is similar to different circulating variants in the USA. All present lineages are descendants of JN.1, which emerged in late 2023,” Norman beforehand advised USA TODAY.
