Variola vaccina.

Zoonosis caused by the poxvirus bovis (orthopoxvirus). Rodents (e.g. rats) are the main reservoir of the pathogen, but humans, cats and cattle can be infected.

  • Risk groups: Atopics, immunosuppressed patients

Transmission occurs via rodents and cattle, but mainly via cats. Skin lesions serve as a portal of entry.

After the appearance of erythema, papulovesicles and pustules, ulceration occurs (after about 2 weeks). In addition to local swelling, painful lymphadenitis is often seen. Sometimes a reduced AZ, febrile temperatures and ocular involvement are seen.
