Recommended case definitions
Rubella control/elimination programs should use the following standardized case definitions, revised from PAHO's Measles Eradication Field Guide, 1999, and the WHO Recommended Surveillance Standards from the 2nd. Ed., June 1999, revised by the PAHO's Communicable Diseases Program.
- Suspected rubella case: any patient in whom a health care provider suspects the possibility of rubella.
In suspected a rubella case, a serum sample should be collected from the patient upon initial contact with the health provider. This sample must be collected within 30 days of rash onset to be considered adequate.
- Laboratory-confirmed case: a suspected rubella case that after complete investigation is:
- Confirmed as rubella using commercially available enzyme immunoassays (EIA) for measles or for rubella IgM antibodies, and/or
- Confirmed by isolation rubella virus and/or
- Epidemiologically linked to another laboratory-confirmed case (the epidemiological link is established if any contact between the suspected case and the laboratory-confirmed case has occurred anytime during the month prior to rash onset).

Rationale for SurveillanceIntroduction:
Rubella virus continues to circulate freely in most countries of the region. After a complete investigation, many suspected measles cases are ultimately found to be rubella. Moreover, cases of the Congenital Rubella Syndrome (CRS) have been found in all countries of the Region that have established CRS surveillance systems. This suggests that CRS is a major public health problem in all countries of the Americas.
