There is no evidence that the strain is spreading in California or the U.S., and the risk of contracting Clade I mpox in the U.S. remains low.

The first case in the U.S. of a more severe strain of monkeypox was reported in San Mateo County, the California Department of Public Health said.

The departures come three days after a scathing report was released that contains seven "sustained findings" against Sheriff Christina Corpus.
