Elevated IgG and IgM antibody titers to parvovirus suggest a diagnosis of: (A) Fifth disease, (B) Susceptibility to chickenpox, (C) Possible subacute sclerosing panencephalitis (SSPE), (D) Possible hepatitis B infection
Answer is A. Fifth disease is a viral exanthem commonly seen in children 8 to 12 years old. Children are ill for a few days but recover without incident. Unfortunately, if a pregnant female acquires the disease in the first trimester of pregnancy, the fetus is at risk. The causative agent is thought to be a parvovirus (parvovirus B 19).
