Additional Measles Cases Reported In Clark County, No New Public Exposure Sites - 02/03/26

Vancouver, Wash. – Six additional cases of measles have been reported in Clark County. The new cases are connected to the measles case announced by Clark County Public Health on Jan. 23. The new cases were exposed to measles in non-public locations. No additional public exposure locations have been identified for any of the cases in Clark County.

“We do not currently have any evidence that measles is spreading in public locations in Clark County,” said Dr. Alan Melnick, Clark County health officer and Public Health director.

Here is additional information about the six new cases:

• Age
  • Younger than 18 years: five cases
  • 18 years and older: one case
• Vaccination status
  • Unvaccinated: five cases
  • Unverified: one case

The MMR (measles, mumps and rubella) vaccine provides the best protection against measles. Two doses of the MMR vaccine are about 97 percent effective at preventing measles. People who are not vaccinated or have not had measles in the past are at risk of getting sick if they are exposed to measles.

Measles is highly contagious and 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.

Anyone who 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.
