On Tuesday, the UK health Security Agency (UKHSA) updated the case definition for monkeypox. In a statement, the UKHSA listed the new symptoms that have been expanded to include a single lesion, lesion on the genitals, anus, and surrounding area, or lesion in the mouth. The new list also added anal or rectal pain and bleeding, especially if the affected individual has had a new sexual partner.

Dr. Meera Chand, Director of Clinical and Emerging Infections at UKHSA, stated that they are visualizing a new diagnosis of monkeypox, passed on primarily through close or sexual contact. She added that they updated the case definition to reflect the clinical presentations that have been seen during the current outbreak. 

In addition to these symptoms, high fever, chills, headache, exhaustion, muscle aches (myalgia), joint pain (arthralgia), backache, and swollen lymph nodes (lymphadenopathy) have been listed as the possible signs of infection. Dr. Chand also advised people with monkeypox symptoms to stay at home and to contact local sexual health services for advice.
