Parvovirus B19 is responsible for a variety of cutaneous diseases, including erythema infectiosum and papular purpuric gloves-and-socks syndrome. It is also associated with other dermatologic diseases, such as systemic lupus erythematosus. To study the prevalence of parvovirus B19 infection in children with acute illness and rash, we did a prospective study of 110 children at the Chiang Mai University teaching hospital from January 2001 to November 2003. ⋯ For those with paired serum samples, there were three patients with recent parvovirus B19 infection that presented with erythema infectiosum, urticaria, and lupus erythematosus, respectively. Immunoglobulin G antibodies were tested in serum samples of 103 children; 28.2% were positive. These data indicate that parvovirus B19 is not a common cause of acute illness and rash in children.
