New monkeypox cases in the UK reach total of 20

UK health officials said on Friday there had been 11 more confirmed cases of the rare monkeypox virus in the country, taking the total to 20.

The announcement came as France, Belgium and Germany reported their first cases of monkeypox and Italy confirmed it now had three linked cases of the disease, which is endemic in parts of Africa.

Cases of monkeypox have also been detected in Portugal, Spain and Sweden, as well as in the United States and Canada, leading to fears that the disease -- normally concentrated in Central and West Africa -- may be spreading.

The UK Health Security Agency (UKHSA) said it had "detected 11 new cases of monkeypox in England", up from a total of nine.

"Most cases are mild and I can confirm we have procured further doses of vaccines that are effective against monkeypox," Health Secretary Sajid Javid tweeted.

The UKHSA's chief medical adviser, Susan Hopkins, said that she expected "this increase to continue in the coming days and for more cases to be identified in the wider community".

The UKHSA said monkeypox had not previously been described as a sexually transmitted infection.

Symptoms of the disease include fever, muscle aches, swollen lymph nodes, chills, exhaustion and a chickenpox-like rash on the hands and face.

It can be transmitted through contact with skin lesions and droplets of a contaminated person, as well as shared items such as bedding and towels.

The first UK case was announced on May 7, in a patient who had recently travelled to Nigeria.

Two more cases were reported a week later, in people in the same household. They had no link to the first case.

It said two new cases reported on May 18 also had no history of travel to countries where the virus is endemic and "so it is possible they acquired the infection through community transmission".

It did not give any details of the latest cases of infection announced on Friday.

On Thursday, health authorities in Italy announced the country's first case of monkeypox, in a young man recently returned from the Canary Islands. On Friday they said two further cases, linked to "patient zero", had been confirmed.

Monkeypox usually clears up after two to four weeks, according to the WHO.
