The CDC states measles is a highly contagious virus that spreads through the air via coughing and sneezing, according to the release. It was publicized earlier that the disease was eradicated in the U.S.in 2000 but has ever since made a return that is attached to imported cases and the growth of the anti-vaccine movement.
Three Multnomah County youths have measles, bringing Oregon's total of measles cases to four. The mainstream of those infected are children, who have not been vaccinated against the disease, executives said.
The Pacific Northwest outbreak includes one confirmed case in King County, where Seattle is located, and one in Multnomah County, which includes Portland, Ore. Israel and Ukraine are now dealing with large outbreaks of measles. "Measles is so contagious that if someone has it, 90 percent of the people around that person who are not immune will become infected".
Under the Expanded Program on Immunization (EPI) of the DOH, the first dose of the MMR vaccine is administered to children aged between 9 and 11 months old while the second dose is given at age 12-15 months old.
The health department said there are two other potential cases of measles that are pending as they wait for test results. "In a sense, we already saw that in 2018, but it looks like cases may pick up more in 2019".
Measles infection typically causes a rash, fever, conjunctivitis (red eyes), cough or runny nose.
"Vaccination is the most effective way to prevent measles", Dr. Matt Richardson, the DCPH Director of Public Health said in a statement.
"Our vaccination rates are not so low that I think we are going to be like Italy or Romania that had thousands of cases past year but we could have a few hundred cases", Ludke said.
According to Montgomery County officials, a 2-year-old girl is recovering from the disease.
The measles, mumps, and rubella (MMR) vaccine is recommended for children because it protects against three potentially serious viral illnesses.
