Spain and Portugal are reporting what could be dozens of monkeypox cases, as the UK Health Security Agency (UKHSA) confirmed two more cases today, bringing the UK total to nine cases since May 6.

More UK cases in MSM

The possibility of community spread is growing more likely in the United Kingdom, as recent cases have no travel history to a country where the virus is endemic. The most recent cases have also been seen in men who have sex with men (MSM).

Though monkeypox is not known to be sexually transmitted, it can be passed through close, personal contact, and via the clothing and linens that have been used by a person with monkeypox.

"These latest cases, together with reports of cases in countries across Europe, confirms our initial concerns that there could be spread of monkeypox within our communities," said UKHSA Chief Medical Adviser Susan Hopkins, MD, in a press release. "We are particularly urging men who are gay and bisexual to be aware of any unusual rashes or lesions and to contact a sexual health service without delay if they have concerns."

Monkeypox cases are typically mild, but they can progress to more severe symptoms and even be fatal. Symptoms usually begin with fever, headache, muscle aches, backache, swollen lymph nodes, chills and exhaustion, with a rash developing on the face and then spreading to other parts of the body.
