Health officials in Multnomah and Marion counties are warning that people in Portland, Salem and Keizer may have been exposed to measles in mid-January.
Officials said a child who arrived in Marion County on Jan. 18 was diagnosed with measles Jan. 23 at Doernbecher Childrens Hospital. The child visited public places in Portland, Salem and Keizer.
The child was at a Marshalls store at Keizer Station from 2 to 5 p.m. on Jan. 20; at a Target store on Keizer Station Boulevard from 3 to 7 p.m. on Jan. 20; and at a Walgreens store on Commercial Street Southeast between 2:30 and 5 p.m. Jan. 22.
Measles is a highly contagious respiratory disease caused by a virus. It is transmitted through the air primarily after a person with measles coughs or sneezes.
Officials warned that people who may have visited or worked at the stores or the hospital should be alert to symptoms such as fever, cough, runny nose and red eyes followed by a red rash that begins at the head and spreads to the rest of the body.
