There's a monkeypox outbreak in the United Kingdom, Portugal and Spain. The outbreak is quite small — just 36 suspected cases spread across the three countries, including eight in England and 20 in Portugal. A case in the U.S. has also been reported.
But health officials have little clue where people caught the monkeypox virus. And there's concern the virus may be spreading through the community — undetected — and possibly through a new route of transmission.
