You may have heard about the ongoing measles outbreak in the U.S. As of July 8, there have been 1,288 confirmed cases in 2025, according to the Centers for Disease Control and Prevention. While most of these cases are in Texas, cases have been rising across the country.
Anyone who isn’t protected against measles can get the illness—and children are especially at risk of getting seriously sick. You may be wondering how to keep your family safe.
“Measles is more than just a rash; it can lead to severe illness, and it’s extremely contagious—you can catch it just from being in the same room as an infected person,” explained Dr. Eric Deussing, Public Health Emergency Officer for the Defense Health Agency. “So, it’s important to take steps to keep you and your loved ones protected and learn how to recognize potential symptoms. Two doses of the measles, mumps, and rubella, or MMR, vaccine provide the best protection against measles.”
Here’s what you need to know.
What is measles?
Measles is a highly contagious illness that can cause serious complications. It spreads through the air when an infected person coughs or sneezes—sometimes, this happens up to four days before they’re even showing symptoms.
People of any age can get serious cases of measles. But the following groups are at increased risk for complications:
- Children younger than age 5
- Adults older than age 20
- Pregnant women
- People with weakened immune systems
Recognizing measles signs and symptoms
Measles symptoms usually appear between seven and 14 days after infection.
Initial symptoms typically include:
- High fever (sometimes above 104 degrees)
- Cough
- Runny nose
- Red, watery eyes
Two to three days after the start of symptoms, you may see tiny white spots (Koplik spots) in your mouth.
In three to five days, you may develop the measles rash—flat red spots that usually start on the face, and then spread down the body towards the feet.
Common complications of measles are ear infections and diarrhea. More severe complications can include pneumonia, swelling of the brain, and other conditions that can lead to hospitalization.
Are you or a family member showing signs of measles? Call the Military Health System Nurse Advice Line at 800-TRICARE (874-2273). Describe your symptoms to a registered nurse, who can advise you on what to do next.
Preventing measles
Your best defense against measles is getting vaccinated. Most people who got their vaccination have protection against measles for life, as
described by the CDC.
Both the MMR and MMRV vaccines are administered in two doses. Children under age 12 should get the first dose between 12 and 15 months old, and the second between 4 and 6 years old. (Children may also get the MMRV second dose three months after the first dose.) Infants ages 6 to 11 months are recommended to get an early dose of MMR vaccine at least two weeks prior to international travel. Prior to travel, talk to your provider or local clinic to ensure your family is fully protected against measles.
Older children, teenagers, and adults should get one or two doses of the MMR vaccine if they don’t have evidence of immunity. (Note: You’re considered immune if you were born before 1957, since it’s likely you were infected naturally.) Doses should be given at least 28 days apart.
TRICARE covers age-appropriate doses of these vaccines, as recommended by the CDC. You don’t need a referral or other approval to get these vaccines. As described in the TRICARE Pharmacy Program Handbook, you can get these vaccines at no cost, as long as you:
If you live overseas, you can get vaccinated at your local military hospital or clinic or by a TRICARE-authorized civilian provider.
