Ted finds out that he has been exposed to the measles and is concerned that he might have contracted the disease. His physician takes a blood sample and sends it to a lab to measure antibody levels. The results show an elevated
level of IgM antibodies to rubella (German measles) virus but very few IgG antibodies to the virus. Did Ted contract the disease?
