First clade I mpox case confirmed in Connecticut after patient traveled to Western Europe

A case of clade I mpox — a more virulent version of the virus that causes monkeypox, according to the Centers of Disease Control and Prevention (CDC) — has been confirmed in the U.S., as global health officials also monitor newly reported hantavirus cases in Europe.

The Connecticut Department of Public Health (CDPH) said Wednesday that the state’s first identified case of clade I mpox was detected in a person who recently traveled to Western Europe, where officials continue to monitor infectious disease activity.
