Oregon Warns of 3-Hour Measles Exposure at Beaverton Trampoline Park

Q: Could one indoor measles exposure in Beaverton lead to secondary spread, and how long should visitors watch for symptoms after July 18?

Yes. One indoor measles exposure at a trampoline park could lead to secondary spread, especially among people who are unvaccinated or otherwise not immune. Health officials say measles is one of the most contagious viruses. It spreads through coughing and sneezing, and virus particles can remain in the air for up to two hours after an infected person leaves. In a crowded indoor setting like Sky Zone Beaverton, that creates a real risk that one infected visitor could expose multiple others, who could then become contagious and pass it on again. Public health sources note one measles case can generate many secondary infections in susceptible groups, though high vaccination coverage sharply reduces that risk. Visitors who were at Sky Zone Beaverton between noon and 3 p.m. on Saturday, July 18, should watch for symptoms for 21 days after exposure. That means monitoring through August 8. Symptoms can begin anywhere from 7 to 21 days after exposure, often starting with fever, cough, runny nose, and red or watery eyes, followed by a rash that typically starts on the face and spreads downward. People who are not fully protected should contact a health care provider promptly, because MMR vaccine can help if given within 72 hours of exposure, and immune globulin may be an option within six days for some high-risk people. Anyone who develops symptoms should call ahead before going to a clinic or urgent care to avoid exposing others.
