U.S. Prepares for Possible Arrival of More Severe Strain of Mpox

The U.S. is preparing for the potential arrival of a more severe strain of mpox, clade 1, which has caused over 24,800 cases and 600 deaths in Africa this year. This strain, more deadly than the clade 2 version seen in 2022, has recently spread to Sweden and Thailand. U.S. officials have expanded mpox surveillance, particularly through wastewater analysis, and are educating healthcare providers about clade 1.

 

The Jynneos vaccine remains effective against both clades, and vaccines are available to high-risk populations. The CDC is coordinating testing and monitoring efforts, while research into new treatments continues, although no specific treatments for mpox are currently approved. Read more from NBC News here.
