A)3 to 5 B)5 to 7 C)12 to 14 D)12 to 15

Production of IgG antibody to rubella virus is not associated with the appearance of clinical signs and symptoms.

If paired specimen testing reveals that the titer of rubella antibody is the same,the results indicate that the:

On American college and university campuses,the susceptibility to rubella infection among students is estimated to be as high as 50%.

In countries in which vaccination is uncommon,the incidence of rubella infection is high and epidemics are frequent.

The risk of fetal anomalies in maternal rubella is highest in the:

The presence of IgM antibody to rubella virus in a single specimen suggests that the patient has recently experienced a rubella infection.

In countries with active rubella vaccination programs,individuals who have not been vaccinated have a higher level of susceptibility to rubella infection.

Individuals requiring rubella immune status determination include pregnant women.

Rubella infection may resemble all the following except:

Fill in the blanks.IgM antibodies against the rubella virus become detectable a few days after the onset of signs and symptoms and reach peak levels at (1)_______.These antibodies persist but rapidly diminish in concentration over the next (2)_______,until antibody is no longer clinically detectable. A)7 to 10 days B)10 to14 days C)2 to 4 weeks D)4 to 5 weeks

Individuals requiring rubella immune status determination include health care personnel.

IgG rubella antibody in a concentration of 1:8 or greater indicates:
