In acute parvovirus B19 infection, anti-IgM titers are what?

Explanation:
In an acute parvovirus B19 infection, the body mounts a rapid initial antibody response, so the anti-parvovirus B19 IgM antibodies rise quickly and are high during the acute phase. IgM is the first antibody type produced in a primary immune response, signalling a recent infection. As the illness resolves, IgM levels fall while IgG antibodies rise and persist, indicating past exposure or immunity rather than current infection.
