Monkeypox: Patient in UK diagnosed with rare virus

A person in England has been diagnosed with the rare viral infection monkeypox, the UK Health Security Agency (UKHSA) has said.

The patient had recently travelled from Nigeria, which is where they are believed to have contracted the infection, before travelling to the UK.

The person is receiving care at the expert infectious disease unit at the Guy's and St Thomas' NHS Foundation Trust, London.

Monkeypox is a rare viral infection that does not spread easily between people but can be spread when someone is in close contact with an infected person.

According to the UKHSA, there is a very low risk of transmission to the general population.

Experts are currently working closely with the NHS, it said, adding it will be contacting people who might have been in close contact with the individual to provide information and health advice.

A number of passengers who travelled in close proximity to the patient on the same flight to the UK will be contacted, the health agency said.

Although people without symptoms are not considered infectious, as a precaution, those who have been in close proximity are being contacted to ensure that if they do become unwell they can be treated quickly, it added.

Dr Colin Brown, director of clinical and emerging infections, UKHSA, said: “It is important to emphasise that monkeypox does not spread easily between people and the overall risk to the general public is very low.

“We are working with NHS England and NHS Improvement (NHSEI) to contact the individuals who have had close contact with the case prior to confirmation of their infection, to assess them as necessary and provide advice.

“UKHSA and the NHS have well established and robust infection control procedures for dealing with cases of imported infectious disease and these will be strictly followed.”

Dr Nicholas Price, director NHSE high consequence infection diseases (airborne) network and consultant in infectious diseases at Guy’s and St Thomas’, said: “The patient is being treated in our specialist isolation unit at St Thomas’ Hospital by expert clinical staff with strict infection prevention procedures.

“This is a good example of the way that the High Consequence Infectious Diseases national network and UKHSA work closely together in responding swiftly and effectively to these sporadic cases.”

Initial symptoms include:

Other symptoms include rashes, which can can develop, often beginning on the face, then spreading to other parts of the body. The rash changes and goes through different stages before finally forming a scab, which later falls off.

According to the World Health Organisation (WHO), monkeypox is a viral zoonosis - a virus transmitted to humans from animals - with symptoms similar to those seen in the past in smallpox patients.

Since 1970, human cases of monkeypox have been reported from 11 African countries – Benin, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Ivory Coast, Liberia, Nigeria, the Republic of the Congo, Sierra Leone, and South Sudan.

In 2017 Nigeria experienced the largest documented outbreak, 40 years after the last confirmed case. The true burden of monkeypox is not known.
