Many countries around the world are facing threats from mutants of Omicron, including the new variant BF.7.

In the United States, the dominance of the Omicron BA.5 variant is declining, and the proportion of the new variant BF.7 is increasing.

BA.5 accounted for 79.2% of U.S. cases in the week ended Oct. 8, down from 81.5% reported last week, according to the latest data from the U.S. Centers for Disease Control and Prevention (CDC).

At the same time, the proportion of BF.7 rose to 4.6%, up from 3.3% in the previous week.

In the UK, BF.7 and two other Omicron variants, BQ variants and BA.2.75.2, have received the most attention. The UK Health Security Agency says they spread quickly and have the ability to escape immunity.

 

In addition, BF.7 also appeared in many other European countries. As of October 13, data from the COVID-19 data repository cov-lineages.org showed that Belgium, Germany, Denmark and France accounted for 18%, 15%, 13% and 8% of recorded BF.7 cases, respectively.

 

BF.7 is the abbreviation of BA.5.2.1.7, and is considered to be the third-generation subtype derived from the BA.5 mutant strain of Omicron.

As of October 12, local time, the World Health Organization has classified BF.7 in its virus surveillance system as “Omicron subvariants under monitoring” (“Omicron subvariants under monitoring”), which means that it may be in the future. Possess an additional risk to global public health requiring priority attention and surveillance.

 

In the World Health Organization’s virus surveillance system, variants are mainly divided into “variants under monitoring” (VUM, Variants Under Monitoring), “variants of interest” (VOI, Variants of Interest) and “variants of interest” according to the degree of risk. Variants of Concern” (VOC, Variants of Concern) three categories.

In view of the fact that the Omicron variant is the mainstream strain in the world and is still evolving, the World Health Organization has added the “Omicron variant under surveillance” on the basis of the original classification.
