Los Angeles is the latest metropolitan area affected by a measles outbreak — the L.A. County Department of Public Health is investigating five cases. Below are answers to commonly asked questions to help you better understand measles, and more importantly, whether you or loved ones are at risk:
What is measles?
Measles is a very contagious respiratory disease spread by breathing, coughing and sneezing. You are contagious before symptoms appear. Without vaccination, you are highly likely to contract the disease when exposed to the virus.
Measles-associated symptoms include:
More than 25 percent of kids age 5 and under who get measles need hospitalization. In some cases, the disease causes:
Why do measles outbreaks occur?
Measles was declared eliminated from the United States in 2000. Yet outbreaks are now on the rise across the country, in part due to international travel. Unvaccinated travelers can contract the disease and unintentionally bring it into the United States. They may have the disease for weeks before they have any symptoms and unknowingly spread it to other unvaccinated people.
Non-vaccination, whether from refusal or forgetfulness, can be problematic. Unvaccinated people who contract measles can easily spread the disease to others who are vulnerable in the community.
What makes someone more vulnerable to measles?
Children who aren’t old enough to receive the vaccine are particularly vulnerable to measles. Public health officials are also concerned about:
Two doses of the vaccine are required for adults (beyond 12th grade) who are at a higher risk for transmission when they:
Am I immune to measles?
One dose of a measles-containing vaccine is 93 percent effective at protecting you from measles, whereas two doses are 97 percent effective. According to TheU.S. Centers for Disease Control and Prevention (CDC), you are protected from measles if you:
Have a laboratory confirmation that you have had measles before or are immune to measles.
Can I get the measles even if I’m vaccinated?
Only three out of 100 individuals who have two doses of the vaccine will get measles. It is unclear why they remain susceptible after vaccination. Fortunately, if you were vaccinated and contract the disease you:
With all the outbreaks, should I be re-vaccinated?
Talk with your provider if you’re concerned about your immunity. You do not need to be re-vaccinated or have a booster dose of the vaccine if you received:
If you cannot recall whether you were vaccinated, you should try to find your childhood vaccine records. If you cannot locate these records, talk with your provider. You and your provider may elect to get a blood test to see if you are immune, or receive a dose of the vaccine. There is no harm in receiving another booster dose even if you previously received one.
What can I do to protect my kids from measles?
The best approach to protect your kids from measles is to have them vaccinated. While no federal laws exist, all 50 states and the District of Columbia have laws requiring vaccinations for children entering a childcare setting or a public school.
The CDC recommends these vaccination guidelines:
Under 12 months
12 months to 12 years
Age 13 and older
What should I do if I’ve been exposed to measles?
After exposure, you may be contacted by the Public Health Department. They would give you specific instructions on what to do and what to watch out for. If you are exposed, your first call should be to your doctor who can help you determine if you are immune or if you need an evaluation. If you are not immune, your doctor may recommend vaccination andyou may potentially have to stay home to monitor your symptoms.
Your provider will also monitor you for any symptoms. If you do have measles, you’ll need to stay home for four days after the rash clears up to avoid infecting others. Your doctor will let you know when it is safe to return to normal activities.
