Congenital Rubella Syndrome

Laboratory confirmation of infection but with no clinically compatible manifestations (see Table 1): Isolation of rubella virus from an appropriate clinical specimen (e.g., urine, nasopharyngeal swab, throat swab, CSF)[1] OR Positive serologic test for rubella-specific IgM in the absence of recent immunization with rubella-containing vaccine OR Detection of rubella virus RNA (e.g., PCR) in an appropriate clinical specimen (e.g., urine, nasopharyngeal swab, throat swab, viral isolate)[1] OR Rubella-specific IgG persisting for longer than would be expected (approximately six months following birth) from passive transfer of maternal antibody, or in the absence of recent immunization
