The 2022–2023 mpox outbreak in Canada is a part of the outbreak of human mpox caused by the West African clade of the monkeypox virus. The outbreak started in Canada on May 19, 2022, with the country since then becoming one of the most affected in the Americas.

Background

An ongoing

community transmission taking place in the London area as of mid-May,[2] but it has been suggested that cases were already spreading in Europe in the previous months.[3]

Transmission

Stages of lesion development.

A large portion of those infected were believed to have not recently traveled to areas of Africa where mpox is normally found, such as Nigeria, the Democratic Republic of the Congo as well as central and western Africa. It is believed to be transmitted by close contact with sick people, with extra caution for those individuals with lesions on their skin or genitals, along with their bedding and clothing. The CDC has also stated that individuals should avoid contact and consumption of dead animals such as rats, squirrels, monkeys and apes along with wild game or lotions derived from animals in Africa.[4]

Symptoms such as fever, headache, swollen lymph nodes, and rashes or lesions are fairly common. Additionally some patients also have presented with proctitis. The Public Health Agency of Canada has noted that person to person transmission of mpox is possible from direct contact with bodily fluids including sexual contact.[5]
