Many of the US cases were caused by the same strain as recent cases in Europe, but a few samples show a different strain, federal health officials said.
Monkeypox Cases: The US Centers for Disease Control and Prevention (CDC) said it was aware of more than 700 global cases of monkeypox, including 21 in the United States, with investigations now suggesting it is spreading inside the country.
Cases of monkeypox have been reported from Britain, Belgium, Australia, Germany, Spain, Portugal, Italy, Canada, Sweden, and the US. Denmark, Israel, and Canary Islands too have reported their first cases.
