Public Health – Seattle and King County work together with the Washington Department of Health, the Tacoma Pierce County Department of Health and the Snohomish Health Department to determine the link between these events.

What to do if you are exposed to measles
Most people in our area are immune to measles through immunization, so the risk to the general public is low. However, people in places that are likely to get measles should:
- Find out if you have measles vaccination or had measles before. Keep your recommended measles immunization count (MMR) up-to-date.
- Call your health care provider immediately if you have a fever or illness due to an unknown rash. To avoid spreading measles to others, do not go to a hospital or a hospital without first telling them that you want to get a measles evaluation.
- In some cases, vaccination or medication may be given to prevent disease after inoculation. This is especially important for people at high risk of measles complications (see below).
Measles symptoms may occur from day 7 after the first exposure to day 21 after the last exposure to measles. Rashes are most likely to appear a few days after fever between 10 and 12 days after fever.

Measles is a highly contagious and potentially serious disease that can cause fever, rashes, coughs and flooding eyes. People with measles usually spread after coughing or sneezing.
Measles symptoms start on days 7 to 21 after measles. Measles is spread from 4 days before the appearance of rash to 4 days after the appearance of rash. People can spread measles before they get measles.
Measles complications can include ear infections, diarrhea, pneumonia, and rare encephalitis (encephalitis). Complications from measles can also occur in healthy people, but the greatest risk is infants under the age of five, adults over 20 years old, pregnant women, and people with weak immune systems due to drug or underlying disease. If you are exposed to measles in one of these high-risk groups, contact your doctor to discuss the need for treatment to prevent measles infection.
Measles, measles and rubella (MMR) vaccines are available to prevent measles. According to the Centers for Disease Control and Prevention (CDC), two doses of the MMR vaccine are effective in preventing measles and have a long lasting protective effect.
Work done by public health officials
Investigating epidemics is one of the essential services provided by the local health department. As national measles activity increases, the Department of Health throughout Washington is working with schools and communities to alert health care providers and provide measles prevention education.
