Eleven new cases of monkeypox have been confirmed in the UK, bringing the total number of recorded cases to 20.
Health Secretary Sajid Javid tweeted he had updated G7 health ministers on what is known about the spread of the virus. He said most cases are "mild".
The Government has some stocks of the smallpox vaccine, which can be effective against monkeypox as the viruses are quite similar. This is being offered to very close contacts of those who have been affected.
