VANCOUVER – Clark County Public Health has identified an additional location where a person with measles visited while contagious last week. Public Health announced the case on Jan. 23, 2026. No additional confirmed cases of measles have been identified to date.
People who visited The Vancouver Clinic’s Ridgefield clinic, 5515 Pioneer St., from 4 to 9 pm Wednesday, Jan. 21 may have been exposed to measles. People who were at the medical office and who have not been vaccinated against measles or have not had measles in the past are at risk for getting sick.
The person who tested positive for measles was also at Ridgefield High School while they were contagious on Jan. 14, 15 and 16.
Anyone who may have been exposed and believes they have symptoms of measles should call their health care provider before visiting the medical office to make a plan that avoids exposing others in the waiting room.
About measles
Measles is a highly contagious and potentially serious illness caused by a virus. Measles spreads through the air after a person with measles coughs or sneezes. The virus can linger in the air for up to two hours after someone who is infectious has left.
After someone is exposed to measles, they begin to get sick in about one to three weeks. Measles symptoms begin with a fever, cough, runny nose and red eyes, followed by a rash that usually begins at the head and spreads to the rest of the body. People are contagious with measles up to four days before the rash appears and up to four days after the rash appears.
Measles poses the highest risk to people who have not been vaccinated, including infants younger than 12 months. The MMR (measles, mumps and rubella) vaccine provides the best protection against measles. One dose of the vaccine is about 93 percent effective at preventing measles. Two doses are about 97 percent effective.
