According to the UK Health Security Agency, the patient has been admitted to the Royal Liverpool University Hospital’s High Consequence Infectious Disease (HCID) ward.
Health officials in the UK have reportedly found the second strain of monkeypox.
A person who recently traveled to West Africa has been diagnosed with a different strain of monkeypox to the one circulating during the current outbreak, the UK Health Security Agency (UKHSA) announced.
The agency said the variant may have been seen in the UK before and that tests are being done to establish this.
The unnamed person has been admitted to the High Consequence Infectious Disease (HCID) unit at the Royal Liverpool University Hospital.
Contact tracing is now being done to establish if there are any further linked cases.
Dr Sophia Maki, it is incident director, said: “We are working to contact the individuals who had close contact with the case prior to confirmation of their infection, to assess them as necessary and provide advice.”
The risk to the public is “very low” due to “well established and robust” infection control procedures, which will be strictly followed, she added.
