Monday brought the third day in a row with no new measles cases. There are still two people suspected of having measles.
Between Oregon and Washington, there have been 58 cases, the worst outbreak in the region’s history.
The respite from new diagnoses and a low number of suspected cases could signal a slow in the spread of the disease, however public health officials say that won’t be sure until at least 21 days without a new diagnosis.
Measles can incubate inside a body for up to two weeks before symptoms show.
The highly contagious virus spreads through the air and can linger for up to two hours in an isolated space. People who have never received a measles vaccine are susceptible to the disease, which can be deadly.
Two doses are 97 percent effective, and public health officials in Washington recommend that everyone who is unvaccinated or only received one get both shots to avoid contracting measles. The vaccine can reduce the risk of infection if gotten within 72 hours after exposure to the virus.
To further limit the spread of the virus, health officials ask that people who think they might have measles call their doctor or health care provider before visiting a hospital or doctor’s office.
