4 more cases of 'monkeypox' reported in the UK: What to know

The four cases do not appear to be related to the first case reported May 7 among a person who had recently traveled to Nigeria.

Several people in England have tested positive for monkeypox, according to the U.K. Health Security Agency.

Officials announced Monday four more cases of the rare disease have been detected, bringing the total to seven.

The most recent infections do not seem to be connected to the first case confirmed May 7 in a person who had recently traveled to Nigeria.

But the most recent four cases had not traveled to a region where monkeypox is endemic, raising the possibility that the virus could be circulating within the U.K.
