BNO News is tracking monkeypox cases around the world. The first known case in the current outbreak was detected in London on 7 May 2022 in a recent traveller from Nigeria, where monkeypox is endemic. The following days and weeks, cases were reported in a growing number of countries, which is atypical for monkeypox. The outbreak involves the West African clade, which is believed to have a case fatality rate of 1%.
There are varying definitions for confirmed cases of monkeypox. A positive PCR test for orthopoxvirus (the family to which monkeypox belongs) is sufficient for confirmation in some countries while others call them "probable" cases until genomic sequencing is complete. BNO News considers cases with a positive test as confirmed.
