Measles
Do not wait for laboratory confirmation, report immediately by telephone for both confirmed and suspected cases upon suspicion of measles. Public Health will guide you through the collection of specimens for testing and management of the patient under investigation as well as asymptomatic contacts for suspected or confirmed cases. Consultation is required before sending specimens to the Public Health Laboratory:
- Weekdays, 8:00 am – 5:00 pm: Call CD Warmline 530-666-8670 (leave a message if you reach voicemail and your call will be returned within 1 hour)
- Non-business hours/weekend: Call EMS Duty Officer 530-321-3620
Clinical presentation
- Immunocompetent patients with measles typically exhibit high fever, with one or more of the “3 C’s” conjunctivitis, coryza (runny nose), and cough. Patients may have erythematous, white or grey specks on the buccal mucosa, commonly referred to as Koplik spots, prior to the onset of rash.
- Two to 4 days after initial symptoms, measles rash usually begins along face and hairline and spreads downwards to trunk. Patients are typically infectious 4 days prior to onset of rash to 4 days after rash.
- Ask about measles vaccination status, onset, and duration of fever and rash, exposure to other measles cases, travel history, and international visitors in the three weeks prior to illness. See the Measles QuickTool for a complete list of questions to ask.
Isolation of suspected cases
- Patients with signs or symptoms of measles should be rapidly identified and isolated from other patients prior to or as soon as possible after entry into the facility.
- If possible, screen patients prior to their arrival at the healthcare setting. Patients with a febrile rash and clinically compatible measles symptoms who are unimmunized or who have had international travel or other potential exposures to measles should be evaluated before clinic opens or after it has closed, to avoid exposing other patients.
- Patients with suspected measles should wear a well-fitted medical mask or respirator and be placed in an airborne infection isolation room if one is available. If this cannot take place, escort masked patient away from other patients directly to a private room for evaluation and specimen collection. Do not use this room again until 2 hours after the patient has departed the room.
- If a private room is not available, evaluation and specimen collection can be considered outside the health center, e.g., in patient’s car.
Vaccine recommendations
- MMR and MMRV vaccine are both safe and highly effective vaccines to protect against measles.
- In immunocompetent individuals, one dose of a measles-containing vaccine is 93% effective against measles, 2 doses are 97% effective.
- For more information on vaccines, see Advisory Committee on Immunization Practices (ACIP) Recommendations for MMR & MMRV (Measles, Mumps, Rubella & Varicella) Vaccines
- Healthcare personnel should have documented evidence of immunity against measles.
- Please report any Vaccine related adverse events to Vaccine Adverse Event Reporting System (VAERS)
