SALEM, Oregon. – Marion County officials say a laboratory report confirms that there is no case of measles in the Salem area.
Negative test results came Saturday afternoon after county officials confirmed they were investigating a suspected case.
There are currently 53 confirmed cases of measles in Clark County and two suspected cases, and it is feared that the epidemic may continue to spread.
Clark County reported that it had no new confirmed cases.
Symptoms of measles begin with a slight fever, cough, runny nose and red eyes, followed by a rash.
If you or your child have gone to one of the possible exposure sites and shown signs of measles, contact your doctor before entering so they can limit someone else's exposure in the waiting room.

Of the Clark County measles cases, officials say most of the patients were not immunized, six people did not have the vaccine confirmed and one person received only one dose of the MMR vaccine.
The CDC says that one dose of the MMR vaccine is 93% effective, while two doses of the vaccine are 97% effective.
Children typically receive the first MMR vaccine at one year to 15 months and the second at 4-6 years.
