Clark County Public Health is investigating a confirmed case of measles in a child who traveled from outside the country to Clark County in late December.
County health officials say people who visited the clinic and waiting area at PeaceHealth Memorial Urgent Care, at 3400 Main St., in Vancouver, between noon and 5:30 p.m., Monday, Dec. 31, may have been exposed to measles.
Clark County Public Health is advising anyone who has been exposed and believes they have symptoms of measles to call their health care provider prior to visiting the medical office to make a plan that avoids exposing others in the waiting room.
County health officials say measles is a highly contagious and potentially serious illness caused by a virus that is spread through the air after a person with measles coughs or sneezes. A person with measles can spread the virus before they show symptoms. The virus also can linger in the air after someone who is infectious has left.
Immunization is the best protection against measles. One dose of the measles vaccine is about 93 percent effective at preventing measles. Two doses are about 97 percent effective, according to the Centers for Disease Control and Prevention.
