Human parvovirus B19 infection: clinical and epidemiological study of 24 cases

From March 1994 to November 1995 24 cases of human parvovirus B19 infection were seen at the Infectious Diseases Department of the Hospital Universitário Antônio Pedro, Niterói - RJ. Serum samples for IgM detection (capture enzyme immunoassay) were positive from the 1st to the 27th day after the onset of the exathema. The classical features of erythema infectiosum (slapped cheecked syndrome) were observed in 8 (33.3%) cases all of them children. Eight patients (6 adults and 2 children) presented a symmetrical polyartropathy, seen more frequently in women. These results show that B19 infection diagnosis is difficult when the disease does not present the classical features and because of the frequent involvement of the joints this infection should be considered in the differential diagnosis of early rheumatoid arthritis.
