Discarded case: a suspected case that was investigated and discarded, either through negative results of adequate laboratory testing for measles and rubella or by an epidemiological link to a laboratory-confirmed case of another disease; in addition, IgM-positive cases in recent vaccine recipients can be discarded if they meet all of the following criteria:
history of vaccination with relevant vaccine 7 days to 6 weeks prior to specimen collection;
onset of rash 7−14 days after vaccination;
no evidence of virus transmission revealed by active search in community;
no history of travel to areas in which the virus is known to be circulating.
