England has reported 14 new cases of smallpox, bringing the UK total to 71.
To date, England has reported 70 cases and one has been confirmed in Scotland, the UK Health Safety Agency (UKHSA) said.
No cases have been reported in Wales or Northern Ireland so far.
Although more cases are detected, the risk to the UK population remains low, the UKHSA added.
He explained that a “remarkable proportion” of the identified cases have occurred among people who identify as gay or bisexual or men who have sex with men.
However, anyone with “unusual rashes or injuries” should contact NHS 111 or their local sexual health service immediately.
Dr. Susan Hopkins, chief medical adviser to the UKHSA, thanked people for showing symptoms and said the agency continues to “quickly identify” cases.
The UKHSA recommends that contacts of smallpox cases with a high risk of catching the infection be isolated for 21 days.
This includes not traveling, providing contact tracking details, and avoiding direct contact with immunosuppressed people, pregnant women, and children under the age of 12.

In Germany, meanwhile, 40,000 doses of the monkeypox vaccine have been prescribed as a precautionary measure.
“If the infections spread further, we will want to be prepared for possible ring vaccines that are not yet recommended at this point, but which may be necessary,” said German Health Minister Karl Lauterbach.
