Urgent Health Alert: Potential Measles Exposure at Sea-Tac Airport!

Travelers at Seattle-Tacoma International Airport are on high alert following a recent report from Public Health — Seattle & King County about a possible measles exposure. An adult individual, who is an Alaska resident and was infectious with the disease, passed through the airport last week, specifically on Friday, January 10.

According to health officials, this person likely contracted measles while traveling abroad. Dr. Eric Chow, the communicable disease chief for Public Health, emphasized the highly contagious nature of measles, stating, “If you don’t have immunity, you can get it just by being in an area where a person with measles has been.

Fortunately, those who are vaccinated against measles are significantly protected. The measles, mumps, and rubella (MMR) vaccine is highly effective; two doses provide approximately 97% lifetime immunity against infection.

However, the threat is real. Measles can remain airborne for up to two hours after an infected person leaves a location. Individuals who were present at Sea-Tac between 2:30 p.m. and 8 p.m. are considered at risk, particularly in areas such as S Concourse (including Gate S8), the international arrivals area, baggage claim (carousel 21), and D Concourse (including Gate D7).

The public is reassured that the risk remains low, but health officials urge vigilance. Anyone who was in these areas should verify their vaccination status. Symptoms of measles can appear within 7 to 14 days after exposure, and if anyone develops fever or rash during the potential illness window (January 17 to January 31), they should contact their healthcare provider immediately.

For those who suspect they've been exposed, Public Health advises against visiting clinics or hospitals without prior notification to avoid spreading the virus. Limiting contact with others during this time is also strongly recommended.

Measles is not just a minor illness; it can lead to serious health complications. Symptoms to watch for include high fever, rash, cough, runny nose, and red, watery eyes. It's a highly contagious disease, with studies indicating that up to 90% of unvaccinated individuals nearby can contract it after exposure.

Travelers, stay informed and take precautions! Your health and that of those around you might depend on your response to this serious public health issue.
