Recovery from parvovirus B19 infection is achieved by production of IgM antibodies which are specific for virus and are generated 10–12 days after infection. After day 16, when signs of erythema infectious (red rashes) and arthralgia (pain in joints) becomes apparent, specific anti B19 IgG is produced by immune cells. Production of serum anti B19 IgG keeps infection under control and facilitates the recovery of erythroid cell production in erythroid lineage cells that were targeted by parvovirus B19.
