Mpox
Last updated on Thursday, 13 November 2025 at 09:30am
Mpox is an infectious disease caused by the MPXV virus. Historically, mpox was known to occasionally pass on from infected animals to humans, with humans sometimes passing it on to other people that they had close contact with. Since May 2022, cases of human mpox have been reported in multiple countries that have not previously had MPXV detected in animal or human populations.
