PORTLAND, Ore.—Oregon Health Authority (OHA) and Clackamas County officials have identified another measles exposure location and are recommending people who believe they were exposed to talk to a health care provider about their risks.

People might have been exposed if they were at the following location at this date and time: 

• Providence Willamette Falls Medical Center, emergency department waiting room, 1500 Division St., Oregon City, between 9:57 p.m. Wednesday, Feb. 25, and 12:22 a.m. Thursday, Feb. 26.  

People who were at this location during these dates and time period should immediately contact a health care provider and let them know they may have been exposed to someone who has measles. The health care provider can determine whether you are immune to measles based on your vaccination record, age, or laboratory evidence of prior infection.

Facts about measles

Measles spreads through the air after a person with measles coughs or sneezes. People are contagious with measles for four days before a rash appears and up to four days afterward. The virus particles also can linger in the air for up to two hours after someone who is infectious has left the area.

Measles typically starts with a fever, cough, runny nose and red eyes. A rash usually follows, beginning on the face and spreading to the rest of the body. Symptoms begin seven to 21 days after exposure to a person with measles. Common complications of measles include ear infection, lung infection and diarrhea. Swelling of the brain is a rare but much more serious complication.

Measles can be dangerous, especially among infants and children younger than 5 years old, adults older than 20 years, pregnant people, and people with weakened immune systems. In developed countries in recent years, one or two out of every 1,000 measles cases has been fatal.  The measles vaccine is highly effective at providing protection, as two doses of the MMR vaccine is 97% effective at preventing measles. The risk of severe disease from measles for people who are up to date on their vaccines is very low.

What to do if you suspect measles in your household 

Public health officials urge people experiencing symptoms of measles not to arrive unannounced at a medical office if they: 

1. Have a measles-like rash, or
2. Have been exposed to measles within the previous 21 days, AND 

 have any other symptom of measles (such as fever, cough or red eyes).

Whenever possible, individuals planning to seek medical care should first call a health care provider or urgent care center by telephone to create an entry plan to avoid exposing others in waiting rooms.
