Oregon health officials warned the public about a measles exposure at Kaiser Permanente Mt. Talbert Medical Office in Clackamas on August 29, according to the Oregon Health Authority and Clackamas County health officials.
People who were at the clinic's first floor between 10:31 a.m. and 6:07 p.m. that day should check their vaccination records and monitor for signs of measles, the agencies said.
The OHA recommends that people born after 1957 who have not had measles and have not been vaccinated against measles should receive an MMR vaccine as soon as possible. For infants, early administration of MMR is being considered as a protective measure during the current measles circulation in Oregon.
Measles typically starts with fever, cough, runny nose and red eyes, followed by a rash that usually begins on the face and spreads to the rest of the body. Symptoms typically appear seven to 21 days after exposure, according to the OHA. Complications can include ear infection, lung infection and diarrhea, with swelling of the brain as a rare but serious possibility.
The measles vaccine is highly effective, with two doses of the MMR vaccine being 97 percent effective at preventing the disease, the health authority said.
