Moneypox Has Likely Spread Under The Radar "For Some Time": WHO

Since Britain first reported a confirmed monkeypox case on May 7, more than 550 confirmed cases of the disease have been verified in 30 countries.

The WHO said Wednesday that hundreds of monkeypox cases have surfaced beyond the African countries where the disease is typically found, warning the virus has likely been spreading under the radar.

"Investigations are ongoing, but the sudden appearance of monkeypox in many countries at the same time suggests there may have been undetected transmission for some time," World Health Organization chief Tedros Adhanom Ghebreyesus told reporters.

Since Britain first reported a confirmed monkeypox case on May 7, more than 550 confirmed cases of the disease have been verified in 30 countries outside of the west and central African nations where it is endemic, the WHO said.

The UN health agency's top monkeypox expert Rosamund Lewis said that the appearance of so many cases across much of Europe and other countries where it has not been seen before "is clearly a cause for concern, and it does suggest undetected transmission for a while".
