Provider Alert

For immediate release: May 15, 2019

Dear Colleagues,

A Pierce County man in his 40’s has been diagnosed with measles. The Tacoma-Pierce County Health Department and Public Health-Seattle & King County are investigating this jointly as he spent a significant amount of time at the Sea-Tac Airport. It is unclear where this patient was exposed to the virus. The onset of his rash was May 10/11, so he was exposed sometime between April 19th and May 1st. Subsequently, this patient spent time working at Sea-Tac during the infectious period. Exposures in the community as a result of this case occurred between May 6th and May 11th. We would expect cases from these exposures to occur between May 13th and June 1st, 2019. As much of his exposure period was at Sea-Tac airport, many of the exposed may have returned to your counties after air travel. Please advise your providers to be on alert for cases of measles that may have had the following exposures:

1. Consider measles infection in patients with compatible symptoms, including:
• Prodrome of fever, cough, coryza and conjunctivitis lasting 2–4 days.
• Generalized maculopapular rash that usually begins on the face.
• Koplik spots may appear on buccal mucosa 1–2 days prior to rash.

2. Assess patients with measles symptoms for local exposures (listed above), domestic or international travel to areas where measles outbreaks are occurring, or potential exposure to a confirmed measles case.

3. Instruct reception/triage staff to identify and isolate patients who present with symptoms of possible measles
• Patients with symptoms of measles should wear a mask covering the nose and mouth and should be kept away from patient waiting rooms.
• Room the patient immediately and close the door.
• Only staff with documented immunity to measles should be allowed to enter the patient’s room.
• After the patient is discharged, do not use the room for 2 hours.

4. Collect specimens on patients with suspected measles:
• Nasopharyngeal swab (preferred respiratory specimen) for PCR and virus isolation.
• Urine (at least 50 ml) for PCR and virus isolation.
• Serum (at least 1 cc) for measles IgM.

5. Call the Yakima Health District with any suspected measles case so that we may expedite lab testing and begin necessary public health investigation. Report suspect cases to Disease Control at (509)249-6541. Measles is a notifiable condition in Washington State:
