evidence: Sweden said Thursday that it had confirmed a case of the more contagious version of mpox circulating in central and eastern Africa. [...] "We have now also during the afternoon had confirmation that we have one case in Sweden of the more grave type of mpox, the one called clade I," Health and Social Affairs Minister Jakob Forssmed said at a news conference. [...] The strain that spread widely in 2022 and prompted the WHO's first public health emergency declaration was a version of clade II. The current outbreak, however, is a version of clade I, which is "likely to be associated with a higher risk of a more severe course of disease and higher mortality," according to the Public Health Agency of Sweden.
