The declaration came on January 25 when the number of confirmed cases reached 26.
The revelation prompted public health officials in Oregon's Deschutes County and in Hawaii to issue alerts, although no cases were confirmed in either location.
Surrounding counties also have more than 90 percent of their school-age children protected from the measles. One case involved an individual who had been immunized.
According to Jackson County Public Health, measles is a preventable disease - the best protection is to get vaccinated with the measles-mumps-rubella vaccine (MMR). Health officials say 41 of the cases are in Clark County, with the remaining case coming from King County.
"Sustaining a high vaccination rate among school children is vital to the prevention of disease outbreaks, including the reestablishment of diseases that have been largely eradicated in the United States, such as measles", the bill states. Vaccination is a fool-proof method to curb the spread of measles.
The measles outbreak that has sickened 38 people in Washington state has spread to Hawaii and OR by travelers with the highly-contagious disease. Because measles is contagious even before people realize they are sick, people who are not vaccinated may unknowingly spread the virus.
If you haven't gotten the vaccination already, you likely still can.
Measles symptoms include a fever, rash, cough, conjunctivitis (red watery eyes) or a runny nose. But it is still a big problem in other parts of the world, and travelers infected overseas can bring the virus back and spread it, causing periodic outbreaks. In some people, especially people who have chronic medical problems, are pregnant, or are malnourished, measles also leads to serious problems such as pneumonia, brain damage, blindness, deafness, and death.
DPH urges healthcare providers to maintain heightened awareness for patients with measles or symptoms of measles. "There is no magic bullet cure to fight it". Since Jan. 1, we have identified 42 confirmed cases and seven suspect cases.
The most serious risk is to children who haven't yet received all of their vaccines, and others who can't be vaccinated for medical reasons (for example, because their immune system is suppressed due to another illness).
And it's especially risky for young children and babies.
Measles virus travels through the air.
Stay home if you are experiencing cold- or flu-like symptoms.
