Abstract: A varíola bovina é zoonose causada pela proliferação de vírus do gênero Orthopoxvirus. Caracteriza-se por lesões papulares que evoluem para vesículas, pústulas e crostas. Dentro do gênero Orthopoxvirus conhece-se os vírus cowpox e vaccínia. O vírus cowpox circula na Europa e Oriente Médio sendo responsável por infecções em roedores, animais domésticos como o gato e em bovinos, nos quais causam a redução da produção de leite. O vírus vaccínia foi utilizado no passado para o preparo da vacina contra a varíola hu… Show more

“…Similar clinical symptoms were observed in humans beings in outbreaks described in other Brazilian states (Nagasse--Sugahara et al 2004, Megid et al 2008, Silva et al 2008, Schatzmayr et al 2009b). Sudoresis, anorexia, toxemia and lymph node swelling were also observed in some human cases (Silva et al 2008, Schatzmayr et al 2009a, 2009b. In comparison with other zoonotic vesicular disease, VACV infection appears to affect more severely and systematically the humans that have contact with the affected cattle (Büttner & Rziha 2002, Silva-Fernandes et al 2009).…”

“…VACV infection is zoonotic and transmission to man usually occurs through handling or milking affected cows (Smith 2007). Lesions in VACV-infected cattle are most frequently observed in teats and udders of milking cows, and in the mouth of suckling calves (Leite et al 2005, Silva et al 2008. In man, skin lesions are painful and occur mainly on the hands and fingers: nodular swellings, papules, pustules, ulcers and scabs.…”

“…In humans, the clinical manifestations of BV are mainly lesions located at the primary site of infection, usually on the fingers and hands of milkers who have a history of unprotected contact with infected animals [12,14,15,17]. However, additional lesions as a result of the self-inoculation process have also been described in other body sites such as the face, eyes, and genital region, and in humans, BV is associated with high morbidity [18][19][20][21]. The process between the onset of the initial symptoms and the healing of the ulcerative skin lesions takes approximately 21 days.…”

“…No rebanho as lesões usualmente têm aspecto vesicular, provocadas por diversos vírus, sendo mais frequentes por vírus cowpox, vaccinia, herpes e a papilomatose. No Brasil, o agente etiológico mais comum é o Vaccinia virus (Silva et al, 2008) e ocorre aumento dos surtos principalmente no período seco, época de maior traumatismo no úbere e tetas, favorecendo a disseminação do vírus no rebanho e também sugerindo uma sazonalidade da doença (Paredes, García, & Figueroa, 2006).…”
