Public Health – Seattle and King investigate a new case of measles with possible exposures in the King County. The resident of King County, a 40-year-old woman, spends time at King County sites before she finds it contagious. This is the third King County case identified this month, adding to the six recent cases of measles in the residents of Washington.
Public Health, Seattle and King, continues to work with the Washington Department of Health, Tacoma-Pierce County Health Department, and Snooshish Health District to identify the links between these cases.
At this stage of the investigation, information on the latter cases indicates a general exposure of an unidentified person infected with measles on April 25, 2019 at Sea-Tac International Airport, probably in the morning. These agencies will provide updates to the public through their social media and websites as there will be more information. Health officials have no reason to believe that there is currently an increased risk of getting measles by visiting the airport.
What to do if you were in a place with potential exposure to measles
Most people in our area have immunity against measles by vaccination, so the risk to the general public is low. However, anyone who has been in places with potential exposure to measles around the periods listed below should:
- Find out if you've been vaccinated for measles or have had measles before. Make sure you keep up with the recommended number of measles vaccinations (MMR).
- Call a healthcare provider in a timely fashion if you develop a fever or illness with unexplained rash. To avoid any spread of measles to other people, do not visit a clinic or hospital without first calling to tell them you want to be rated as measles.
- After exposure, in some cases, vaccination or medication may be given to prevent disease – consult your doctor. This is especially important for people at high risk of complications from measles (see below).
The symptoms of measles may occur seven days after the first exposure until twenty-one days after the last exposure to someone with measles. The rash is most likely to occur several days after fever, ten to twelve days after exposure.
Potential exposition of measles in the King County
The transmission of measles can happen before people know they have a disease before a rash occurs. Before diagnosing measles, the infected individual is in the following public places.
These times include the period in which the person was in place and two hours thereafter. The measles virus may remain in the air for up to two hours after a measles-infected person leaves the area. Anyone who was in the following places during the listed times may have been exposed to measles:
|05.10.2019||7:30 – 9:35||The building of villas A (1221 A St NE, building A, Auburn WA 98002)|
|05.10.2019||8:00 – 19:00||Box Creator (6406 S 190th St, Kent 98032)|
|05.10.2019||17:30 – 20:20||The building of villas A (1221 A St NE, building A, Auburn WA 98002)|
|05.11.2019||15:55 – 18:50 hours||The building of villas A (1221 A St NE, building A, Auburn WA 98002)|
|05.11.2019||16:00 – 19:00||Fred Meyer (801 Auburn Way N, Auburn 98002)|
|15.05.2019||8:30 – 1:25 pm||The building of villas A (1221 A St NE, building A, Auburn WA 98002)|
As more places are identified, they will be added to the list of all measles and exposure locations in King County at kingcounty.gov/measles/cases.
More information about other cases in Washington can be obtained from the Washington Department of Health.
Measles is a highly contagious and potentially severe disease that causes fever, rash, cough, and red, watery eyes. It spreads mainly in the air after a person with coughing or sneezing.
Symptoms of measles begin seven to 21 days after exposure to someone with measles. The measles is contagious approximately four days before a rash occurs four days after a rash occurs. People can spread measles before they have a characteristic rash of measles.
Complications of measles may include ear infections, diarrhea, pneumonia, and rarely encephalitis (inflammation of the brain). Complications of measles may occur even in healthy people, but those at highest risk include: infants and children under 5, adults over 20 years of age, pregnant women and people with a weakened immune system or a primary illness. If you are in one of these high-risk groups and have been exposed to measles, be sure to contact your doctor to discuss the need for treatment to prevent measles infection.
Measles are prevented by a safe and highly effective vaccine against measles, mumps and rubella (MMR). According to the Centers for Disease Control and Prevention (CDC), two doses of the MMR vaccine are more than 95% effective for preventing measles and this protection is prolonged.
What do public health workers do?
Research into infectious diseases is one of the main services provided by local health services. Due to increased measles activity at national level, Washington Health Departments also warn health workers and work with schools and communities to provide education for measles prevention.
