Washington state has had more measles cases so far this year than in the past five years combined, according to the Washington State Department of Health.
This year the state has had 27 cases of measles already, compared to five cases last years.
The resurgence is due in part to people not being vaccinated and the fact that measles is still common in many parts of the world, including parts of Europe, Asia, the Pacific and Africa, according to the Department of Health.
Infected travelers bring the disease to the United States and it spreads in groups of people who are not vaccinated.
Never miss a local story.
Benton and Franklin counties had a serious measles outbreak in 1990. Within a month, 105 people had the illness and two women in their 30s had died.
People who are not vaccinated and develop a fever and rash should seek medical care immediately. They should call ahead to the doctor’s office or emergency room to avoid exposing others in waiting rooms.
