Health Advisory: Measles

Dear Community Partners,

Given widespread outbreaks in the United States and internationally, and locally-acquired cases, the chance of exposure to measles is increased at this time. In response, the LA County Department Public Health is reaching out to community partners to share information about measles and steps you can take to protect yourself and your community.

About Measles
Measles is considered among the most contagious viruses in the world. About 90% of people who have never been immunized against measles become ill 7-21 days after exposure. Infected people can infect those around them before they have symptoms and know they are infected. Common symptoms of measles include fever, cough, runny nose, conjunctivitis (red eyes) and a rash which usually appears 10 to 21 days after the exposure. The measles virus can be transmitted from one person to another up to 4 days before the onset of rash.

Individuals should contact their healthcare provider by phone before going in if they develop measles symptoms, so measures can be taken to prevent possible spread to others in the provider’s waiting room. They should also tell their doctor or other healthcare provider if they traveled internationally or had international visitors in the last 21 days or had exposure to another person with measles.

How can you protect yourself?
Getting immunized is the best way to keep from getting and spreading the measles. We are asking people to talk with their health care provider about the measles-mumps-rubella (MMR) immunization if you haven’t been vaccinated or if you don’t know if you have been vaccinated before. Vaccines are also available at our Public Health Centers for uninsured or underinsured.

What can you do to help?
Please help us spread accurate and reliable information to our community. We are sharing social media pieces (see attached and the links below) with you and we asked that if your organization has a social media platform, that you post and share this information with your community.

The following materials may be of interest for sharing through social media, websites, newsletters, and offices.
