Abstract
To the Editor: Swinepox virus (SWPV), which replicates only in swine, belongs to the Suipoxvirus genus of the Poxviridae family. It is the etiologic agent of a skin disease of pigs, characterized by generalized pustular lesions and associated with high rates of illness (occasionally >80%). It occurs mainly on farms with poor management and housing conditions and affects primarily pigs <3 months of age; adult pigs show milder signs. The disease is mechanically transmitted by pig lice or through direct animal contact (1). Vaccinia virus (VACV; Orthopoxvirus genus) also causes a similar pustular disease in pigs that is difficult to distinguish clinically from SWPV infections. VACV infections were common during smallpox vaccination campaigns, when VACV was transmitted to domestic animals from lesions of vaccinees (1,2).

Sporotrichosis caused by Sporothrix globosa in Rio de Janeiro, Brazil: case report
Distinguishing between Swinepox virus (SWPV) and Vaccinia virus (VACV) infections during outbreaks of pustular disease in pigs is essential for evaluating whether VACV infection might have spread to pigs and whether SWPV could be detected in Brazil
We describe the molecular identification of SWPV as the etiologic agent of an outbreak of pustular disorder in pig herds
