Three of the 73 confirmed cases of measles were people who received one dose of the MMR vaccine.

VANCOUVER, Wash. — Clark County health officials identified another confirmed cases of measles, officials said Monday. There are now three of the 73 confirmed cases in which the person had received one dose of the MMR vaccine.

Of the people found with the virus, 63 were unvaccinated and three people received one dose of the vaccine. It's unclear whether the other seven cases received the vaccine.

“The measles vaccine isn’t perfect, but one dose is 93 percent effective at preventing illness,” said Clark County health officer Dr. Alan Melnick. “The recommended two doses of the measles vaccine provide even greater protection – 97 percent.”

Of the 73 confirmed cases in Clark County:

53 cases were found among children ages 1 to 10

15 cases were found among children 11 to 18

1 case was found among adults 19 to 29

4 cases were found among adults 30 to 39

One child was hospitalized but has since been released.

Washington Gov. Jay Inslee declared a state of emergency on Jan. 25 in response to the measles outbreak. In addition to the Clark County cases, a Seattle-area man who recently visited Southwest Washington has measles, officials said.

Inslee's proclamation and Clark County's previous declaration of a public health emergency makes more statewide resources available to address the outbreak.

The outbreak also spread to Oregon, where health officials said four Multnomah County residents had gotten measles, and the cases were linked to the Washington outbreak.

"These individuals did everything right," said Jennifer Vines, Multnomah County deputy health officer. "They stayed away from others while on symptom watch so we have no new public exposures to measles."

Health officials said two people who are confirmed measles cases in Washington traveled to Hawaii, but there are no known additional exposures linked to that trip. Another person who is a confirmed case traveled to Bend, Oregon. Anyone who visited Mountain Air Trampoline Park on Jan. 19 and Juniper Swim and Fitness on Jan. 20 may have been exposed.

Clark County Public Health is requiring students and staff who do not have documented immunity to measles to stay away from schools identified as possible exposure sites.

People with the disease may have exposed others at health clinics, schools, restaurants and other locations, including Portland International Airport and the Moda Center. A full list of exposure sites listed below.

Clark County Public Health has opened a call center for questions related to the investigation. Anyone who has questions about public exposures should call (360) 397-8021. The call center hours are 9 a.m. to 5 p.m. seven days a week.

Health officials say anyone who was exposed or believes they may have symptoms of measles should call their health care provider prior to visiting a medical office.

People who have been identified as possibly being exposed to measles may receive an automated call from Clark County Public Health. The first automated call will come from the county call center (360-397-8021).

Those who receive calls will be asked if they're showing symptoms of measles. These calls will help Public Health more efficiently gather information about symptoms and identify possible new cases sooner.

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, according to health officials.

Measles is a highly contagious and potentially serious illness. People with measles can spread the virus before they show symptoms. It is spread through the air when a person with measles coughs or sneezes.

The people at the highest risk are those who haven't been vaccinated, pregnant women, infants 12 months or younger or people with weakened immune systems.

Anyone with questions about measles infection or vaccination should call their primary care provider or local county health department:
