Although human Orf virus infections have typically been associated with occupational animal contact (1-3,6), they also have been linked to Muslim religious practices and, more globally, to household meat processing or animal slaughter (4,11-15).
Today, however, Muslims in developed countries (especially in cities) mostly buy lambs, which are cheaper and more plentiful but also highly susceptible to Orf virus infections (7).
Persons at increased risk for exposure to Orf virus include livestock owners, slaughter-house workers, and persons who prepare animals at home for religious practices.
