The Centers for Disease Control and Prevention expressed concern Tuesday about an unusual outbreak of monkeypox in the United Kingdom, suggesting there appears to be at least some undetected transmission of the virus there and warning of the possibility that the outbreak could spread beyond U.K. borders.
“We do have a level of concern that this is very different than what we typically think of from monkeypox. And I think we have some concern that there could be spread outside the U.K associated with this,” Jennifer McQuiston, a senior CDC official, told STAT in an interview.
