Monkeypox is a rare disease caused by infection with the monkeypox virus.
Most cases have been in Africa. The risk of catching monkeypox in the UK is very low.
It's usually a mild illness that will get better on its own without treatment. Some people can develop more serious symptoms, so patients with monkeypox in the UK are cared for in specialist hospitals.
There have been 3 cases of monkeypox in the UK in September 2018. The first 2 were in people who had travelled from Africa.
The third person was a healthcare worker who cared for one of the 2 first cases. The healthcare worker was infected before monkeypox was suspected and special precautions were put in place.
Public Health England has already contacted everyone who was known to be in close contact with the 3 infected people.
If you haven't been contacted by Public Health England, be reassured you are extremely unlikely to catch monkeypox.

Monkeypox does not spread easily between people, but it's possible to catch it from:
It's difficult to know if the infection is monkeypox as it can often be confused with other infections such as chickenpox.
It is diagnosed after an examination by a specialist and testing by Public Health England.
Treatment for monkeypox aims to relieve the symptoms and takes place in specialist hospitals.
