Requested actions

Immediately report suspected measles cases. Call the reporting line: 360-778-6150.

Consider measles in patients with these symptoms:

  • Prodrome of fever, cough, coryza, and conjunctivitis for 2–4 days.
  • Generalized maculopapular rash. Typically begins on the face at the hairline and spreads downward to the neck, trunk, and extremities.
  • Koplik spots may appear on the buccal mucosa 1–2 days before the rash.
  • Patient typically appears very ill.
  • Suspected Measles Case Checklist may help with clinical evaluation.

Immediately isolate patients with suspected measles:

  • Instruct reception and triage staff to identify patients with measles symptoms.
  • Patients with suspected measles should wear a mask covering their nose and mouth.
    • Patient should remain masked during the entire visit.
  • Immediately triage the patient away from the waiting area.
  • Immediately room the patient and close the door.
    • Place the patient in negative pressure isolation, if available.
    • The exam room door should remain closed.
  • Only staff with documented immunity to measles should enter the patient’s room.
    • All staff—even those with immunity—should wear PPE (personal protective equipment).
    • Modified measles cases have occurred in vaccinated healthcare workers with documented immunity.
  • After the patient is discharged, do not enter the room for 2 hours.

Collect specimens from patients with suspected measles for diagnostic testing:

  • For PCR (polymerase chain reaction) and virus isolation:
    • Nasopharyngeal swab placed in VTM (viral transport media).
    • Urine (minimum 20 mL) in a sterile, leak-proof container.
  • For measles IgM (immunoglobulin M) serology:
    • Serum (minimum 1 mL) in a red top or red-grey top tube.

While the patient is still in the office, call Whatcom County Health and Community Services. We will coordinate transporting the specimen to Washington State Public Health Lab.
