A case of pseudocowpox

Pseudocowpox (milker's nodules) is s zoonotic virus infection in cows, less frequently sheep and goats, which is characterized by varioliform lesion on the teats, may be transmitted to man at hand or even mechanical milking, and now occurs rarely in human beings.
Cows are ill with two pox diseases caused by various viruses. One of them is pseudocowpox (vaccinia) virus that gives rise to persistent immunity in man against human pox; the other is its relative virus that causes cowpox called paravaccinia that can is transmitted to man, by developing a short-term immunity (not more than several months).
The latter is known as milker's or dairymaid's disease. Cowpox can spread from animals to human beings with a weakened (or none) immunity against smallpox. Sporadic cases are generally notified. Only sick animals are a source of cowpox infection for man.
In 2010 in the Ulyanovsk Region there was a notified case of cowpox in a female patient who complained about edema in both hands, fusing red papillomas that spread to the elbows and forearms, and red spots on the left face, and herpes-like lip pimples. The patient said that she had milked cows that had warts (nodules) and cuts on the udders.
