Public Health has also identified 12 suspect cases, and one new exposure location: Word of Grace Bible Church, 1317 N.W. 12th Ave., Battle Ground, 9:30 a.m.to 2 p.m. January 20. Authorities say nine additional cases are suspected.
Twenty-five of the Clark County cases are between the ages of 1 and 10; 10 are between 11 and 18; and one case is between 19 and 29. The first known patient sought medical care on December 31, but it isn't known if other people may have gotten sick before that and did not seek treatment.
"Because we don't see (measles) that often anymore, it's sort of out of people's consciousness as a health threat", said Louisa Castrodale, an epidemiologist with the Alaska Department of Health and Social Services. Certain groups need two doses of MMR, including: college students, health care workers, global travelers, and persons at high risk for measles complications. A rise in the percentage of unvaccinated children has directly led to a rise in the number of cases of the potentially fatal disease. OR also has a high nonmedical exemption rate for vaccinations-one 2018 state analysis found a rate among kindergarteners of 7.5 percent, with the number for K-12 students climbing as high as 10 percent in some counties.
In 2018, 349 cases of measles were confirmed in 26 states and the District of Columbia, the CDC reported.
Counties like King are at 91 percent, Snohomish 90.2 percent and Pierce 92.1 percent. This particular outbreak has spread to 31 people who were not immunized and four people who were "unverified".
In 1978, the CDC set a goal to eliminate measles from the United States by 1982.
The State of Alaska has a whole website dedicated to Measles.
"Some of the challenges for Washington state is that there are a lot of rural issues, they may not be opposed to vaccines but they just have a problem getting to the doctor", Koenig said. She knows some people in her community choose not to vaccinate their kids, and it's not worth putting her family at risk. Although it's not clear where he became infected, the man said he'd recently traveled to Clark County. However, the fractured state of the public health system in the USA allows millions of parents to be granted exemptions by states and localities from their children receiving the MMR vaccine.
Children under the age of one can not be immunized.
The death rate is very low for measles, but state health experts are more anxious about serious complications from it. It's spread through those common winter companions, sneezing and coughing.
Clark County, which includes the Portland bedroom community of Vancouver, Washington, has a measles vaccination rate of 78 percent, well below the 92 to 94 percent rate required for so-called "herd immunity", said Marissa Armstrong, the department's spokeswoman.
Adults should have at least one dose of MMR vaccine. "People are delaying immunization for their children because they are concerned about this very small, precious 12-month-old", Dr. Neal Halsey of Johns Hopkins Bloomberg School of Public Health told NBC News.
