UK Health Security Agency (UKHSA) have updated the case definition for monkeypox to include new symptoms.
In light of clinical experience during the outbreak, the symptom list has been expanded to include a single lesion or lesions on the genitals, anus and surrounding areas, lesions in the mouth, and symptoms of proctitis, which include anal or rectal pain or bleeding, especially if the individual has had a new sexual partner recently. It is believed this will help both individuals and clinical professionals identify monkeypox symptoms.
The majority of people with monkeypox can "safely manage their symptoms at home" and there have been no deaths in the UK. Most people experience "mild disease" but it can cause a significant illness in some, requiring hospitalisation, including severe pain.
