A confirmed case of measles has been confirmed in an adult woman who was visiting from British Columbia, Canada. British Columbia is currently having a measles outbreak with 44 confirmed cases.

The only site locally where persons were potentially exposed to measles is the Seattle Aquarium on April 3, from 3-7 p.m.

Because most people in this area are vaccinated against measles, the risk to the general population is low. Persons who are unvaccinated, pregnant women, infants less than six months of age and persons with weakened immune systems are at higher risk if exposed to measles and should contact their health care providers promptly if they develop an illness with fever or an unexplained rash illness.

If members of the public become ill with measles related to this case, they would be expected to develop rash onset between April 10 and April 24. People who may have been exposed are asked to look out for symptoms and contact their health care provider if they become ill. Public Health – Seattle and King County has notified the affected location where community members may have been exposed.
