That brings the total number of measles cases in OR up to four.
The Centers for Disease Control and Prevention (CDC) recommends two doses of measles vaccine, one given at between 12 months and 15 months of age and one between ages 4 and 6. Anyone born since 1978 who is unsure if they have received two doses of a measles containing vaccine, such as MMR, should speak with their GP.
Outbreaks, or clusters, of measles cases are typically due to exposure in foreign countries that do not have the same robust vaccination programs as the United States, Espinoza said.
These new Multnomah County cases are linked to the Clark County outbreak. If exposed to the virus, anyone who is not immune is likely to get measles. That includes attending church by video feed and working with employers. The amount of measles vaccines given out in Multnomah, Clackamas and Washington counties for the last week of January was three times as high as the same period a year ago. Here's what you need to know. The CDC notes that two doses of the MMR vaccine are 97 percent effective, while one dose is 93 percent effective.
In the event of a measles outbreak, WAC 246-105-080 authorizes schools (public or private), child care centers, or the local Health Officer to exclude any child or staff who does not have appropriate documentation of immunity against measles. "It has also raised an awareness that measles could easily make a comeback, and the only way to prevent that is to get as many people vaccinated as possible". The vaccine can reduce the risk of infection if gotten within 72 hours after exposure to the virus. Three times as many people have gotten vaccinated in January - from 200 per day in 2018 to 600 per day in 2019.
The three individuals involved in the new cases were in close contact with the first Multnomah County resident who tested positive for measles January 25, according to the Oregon Health Authority.
