Advice about mpox

Mpox (previously known as monkey pox) is a rare viral infection that spreads through close person-to-person contact. 

There are two major types or ‘clades’ of mpox, known as clade 1 and clade 2. Clade 2 mpox, which appears to be a less severe strain, has been present in the UK since 2022, however only a small number of people in the UK have had mpox. 

Clade 1 mpox has previously only been reported in five countries in central Africa but there is now increasing transmission of Clade 1 mpox in several countries in east and central Africa.

There are currently no confirmed cases of clade 1 in London, or anywhere else in the UK. Therefore the overall risk to people living here remains low. However if you have recently travelled to the affected countries please be aware of signs and symptoms and contact NHS 111 for advice if you have any concerns.
