Two people have been diagnosed with monkeypox in London, health officials said.
The pair live in the same household and are not linked to the previous confirmed case in England that was announced on 7 May, the UK Health Security Agency (UKHSA) said.
Of the latest two cases, one person is receiving care at the infectious disease unit at St Mary’s hospital, Imperial College healthcare NHS trust in London.
The other is isolating and does not currently require hospital treatment, the UKHSA said.
Health officials said they were investigating where and how the infections were acquired.
People who might have been in close contact with either person were being contacted and given information and health advice, the agency said.
Dr Colin Brown, the UKHSA’s director of clinical and emerging infections, said: “We have confirmed two new monkeypox cases in England that are not linked to the case announced on May 7.
“While investigations remain ongoing to determine the source of infection, it is important to emphasise it does not spread easily between people and requires close personal contact with an infected symptomatic person. The overall risk to the general public remains very low.
“We are contacting any potential friends, family or contacts in the community. We are also working with the NHS to reach any healthcare contacts who have had close contact with the cases prior to confirmation of their infection, to assess them as necessary and provide advice.”
