VANCOUVER, Wash. (AP) — County health officials say one more person has been diagnosed with measles linked to a Vancouver-area outbreak.

The Oregonian/OregonLive reports the total number of people diagnosed in Oregon and Washington due to the outbreak since Jan. 1 is now at 78.

The Clark County Public Health Department says the newest confirmed case is in a person age 30 to 39.

Health officials also are investigating two more suspected measles cases. There are no new locations where people may have been exposed to the disease.

Health officials say three additional people in Oregon who have contracted measles did not get it from the Vancouver-area epidemic.

Measles is a highly contagious virus that spreads through the air and can linger for up to two hours in an enclosed area.
