Sera of 500 residents were screened for parvovirus B19 immunoglobulin M (IgM) and immunoglobulin G (IgG) by enzyme-linked immunosorbent assay. Positive IgM and equivocal IgG or IgM results were confirmed by immunofluorescent antibody and Western blot. IgM was detected in 13 sera (2.6%), and IgG was detected in 285 (57%). Records of IgM-positive residents contained no evidence of erythema infectiosum or polyarthropathy.
