Measles (Rubeola) remains a common disease in other parts of the world including areas in Europe, Asia, the Pacific and Africa. In 2000, measles was declared eliminated in the United States (U.S.). However, since the beginning of 2019, there has been a dramatic increase in the number of measles cases in the U.S.
In April 2019, the number of measles cases identified since January 2019 in the U.S. had already exceeded the total annually reported number of cases for each year from 2000 to 2018. The majority of cases have been associated with international travel (imported cases) and localized outbreaks (indigenous cases). Someone returning from international travel while sick with measles can spread the disease to susceptible people in their communities. Although measles vaccination rates in the U.S. and in California are high overall, there are some communities with high rates of unvaccinated, susceptible people.
Measles is characterized by fever followed by a descending, maculopapular rash. Measles usually begins with a high fever and one or more of the “3 Cs”: cough, coryza, conjunctivitis. The rash develops after the fever and typically appears first on the face, along the hairline, and behind the ears and then spreads downward to the rest of the body. The rash is eythematous and maculopapular, progressing to confluence in the same order as the spread of the rash. Confluence is most prominent on the face. The rash begins to clear on the third or fourth day in the same order it appeared. Fever typically peaks 2 to 3 days after rash onset.
People with measles are usually contagious from about 4 days before through 4 days after rash onset.

Laboratory testing with reverse-transcription polymerase chain reaction (RT-PCR) is the preferred testing method when there is strong clinical suspicion of measles. Serology testing is for determination of immunity only and should not be used to rule out measles in a symptomatic patient.
Coordination of lab testing through Public Health should be initiated since Public Health Laboratories are currently the only laboratories in the U.S. that offer RT-PCR testing for measles (rubeola).
- COLLECT specimens:
- Urine (10-50 mL in sterile container), AND
- Dacron swab of throat (preferred) or nasopharynx in viral transport media (VTM)
- SEND specimens to Contra Costa Public Health Laboratory
- Prior testing approval is needed from Contra Costa Public Health and obtained when reporting the suspect case.
- Individual arrangements are needed for the delivery of specimens to Contra Costa County Public Health Laboratory.
- Include completed Laboratory Requisition Slip for each specimen in the shipment.
Place patient in a negative pressure room when available; if not, examine the patient outside the facility or in a private room with the door closed; minimize the time patient spends in the facility. Other precautions apply.
