By OHA: The Oregon Health Authority (OHA) confirmed a second case of measles in August on Tuesday. A person diagnosed on Sunday, August 19, had close contact with a person diagnosed with measles on August 10.
OHA and local health authorities had alerted the person and actively monitored the case. On August 10, OHA received confirmation of the first measles case in an infectious person in the Portland Metro area between July 30 and August 6. "Measles are one of the most contagious diseases we know," said Rebecca Pierce, RN, PhD, OHA's Department of Acute and Communicable Diseases. "It takes very high vaccination rates in the population to stop the spread." OHA has worked with local health authorities to inform people about their potential exposure and to inform them of steps they should take if they become ill to prevent more cases. This person left the state for part of the infectious period and, after becoming ill, followed the recommended precautions to avoid exposing others. Measles is a highly contagious viral disease that can easily spread to people who are not immune. It is spread through the air after a person coughs or sneezes with measles. People with measles can transmit the virus to others before they show symptoms. The virus can also stay in the air for minutes to hours after someone who is infectious has left. Most Oregon residents are vaccinated against measles, and their risk is low. The risk may be higher for unvaccinated persons located in these locations:

There was no link between this case and the measles cases that took place in June and July in Multnomah County, she said. Measles pose the highest risk to unvaccinated persons, pregnant women, infants under 12 months of age, and immunocompromised people. A person is considered immune to measles if any of the following conditions are true:
- They were born before 1957.
- Your doctor has diagnosed you with measles.
- A blood test proves that you are immune.
- They vaccinated against measles (two doses)
The symptoms of measles begin with fever, cough, runny nose and red eyes, followed by a red rash that usually starts the face and spreads to the rest of the body. People are infectious with measles for four days before the rash appears and appears up to four days after the rash. Common complications of measles are ear infection, lung infection and diarrhea. Swelling of the brain is a rare but much more serious complication. In developed countries, one to two out of 1,000 children with measles die from the disease. After someone is exposed, the disease usually develops in about two weeks, sometimes longer. Oregon public health officials advise anyone who believes they have symptoms of measles to call their health care provider or emergency care center first by phone to create an entry plan to avoid exposing others to waiting rooms. If you have questions about measles or measles vaccines, you should contact your family doctor or the local health authority.
