Today, the virus is found in Europe, mainly in the UK. Human cases are very rare (though in 2010 a laboratory worker contracted<unk>  and most often contracted from domestic cats. Human infections usually remain localized and self-limiting, but can become fatal in immunosuppressed patients. The virus is not commonly found in cattle; the reservoir hosts for the virus are woodland rodents, particularly voles. Domestic cats contract the virus from these rodents. Symptoms in cats include lesions on the face, neck, forelimbs, and paws, and, less commonly, upper respiratory tract infections. Symptoms of infection with<unk>  virus in humans are localized, pustular lesions generally found on the hands and limited to the site of introduction. The incubation period is nine to ten days. The virus is most prevalent in late summer and autumn. Immunity to<unk>  is gained when the smallpox vaccine is administered. Although the vaccine now uses vaccinia virus, the poxviruses are similar enough that the body becomes immune to both cow- and smallpox.
