We, here, report the case of a parvovirus B19 infection in an immunocompetent male patient presenting with acute hepatitis and polyarthritis. To follow the course of infection, we used a previously established enzyme-linked immunosorbent spot assay (ELISPOT) technique to detect CD4+ T cells specific for viral proteins. Even though symptoms of arthritis and hepatitis resolved in the immunocompetent individual within a few weeks, viral DNA in serum and CD4+ T cells specific for the viral protein VP1 unique region were still detectable more than 6 month after the onset of symptoms, thus pointing to a persistent state of infection. On the basis of this observation, we hypothesize that the intensity of liver involvement correlates with the likelihood of developing persistent parvovirus B19 infection. The described ELISPOT technique to detect virus-specific CD4+ T cells provides an excellent tool to analyse the state of parvovirus B19 infection for future studies to test this hypothesis.
