Measles is a highly contagious viral infection that can lead to serious health complications. While there is no cure, the good news is that measles can be prevented with vaccination. At the Children’s Clinic in Jackson, TN, we want to help parents stay informed and protect their little ones from this preventable illness.

Is Measles Making a Comeback?

Once nearly eliminated in the United States, measles cases are rising again in areas where vaccination rates have declined. Thanks to childhood immunization programs, measles cases dropped by over 99% since 1963. However, unvaccinated travelers visiting or returning from other countries can bring the virus back, leading to local outbreaks.

Once a case is reported in a community, it is considered an outbreak because of how rapidly the virus spreads. Health officials must act quickly to contain it and prevent further infections.

Travel Precautions for Families with Young Children

If you are traveling internationally, take extra precautions to protect your child from measles:

Infants under 6 months: Too young for vaccination but may have some protection from antibodies passed through pregnancy. If possible, delay travel to areas with outbreaks.
Infants 6 to 11 months: Should receive an early dose of the MMR vaccine at least two weeks before traveling. They will still need the routine two-dose series after their first birthday.
Children 12 months and older: Should receive their first MMR vaccine dose, followed by a second dose at least 28 days later if traveling.
Before traveling, check the CDC Travel Health Notices for updates on measles outbreaks and vaccine recommendations.

At the Children’s Clinic in Jackson, TN, we recommend scheduling a pre-travel consultation to ensure your child is up to date on all necessary vaccinations.

How Contagious is Measles?

Measles is one of the most infectious diseases in the world. Nine out of ten unvaccinated people exposed to the virus will catch it. The virus spreads easily through airborne droplets from coughs or sneezes and can remain in the air or on surfaces for up to two hours.

How Long is Someone Contagious?

A person with measles can spread the virus four days before and four days after the rash appears—often before they even realize they are sick.

How Does Measles Spread?

The measles virus travels through the air, meaning someone can contract the disease simply by being in the same room where an infected person was hours earlier. It can even spread through air currents to infect people in different areas of a building.

Symptoms of Measles

Measles symptoms typically appear 8 to 12 days after exposure and often include:

High fever
Cough, runny nose, and red, watery eyes
Small white spots inside the mouth (Koplik spots)
Rash that starts on the face and spreads downward
Diarrhea and ear infections (in some cases)

Complications of Measles

Measles can lead to serious health issues, including:

Pneumonia
Encephalitis (brain swelling)
Hearing loss or intellectual disabilities
Severe cases can result in death

How Long Should a Child with Measles Stay Home?

Children diagnosed with measles should stay home at least four days after the rash appears to prevent spreading the virus.

Should Unvaccinated Children Attend School During an Outbreak?

During an outbreak, unvaccinated children may need to stay home. Specific recommendations include:

Unvaccinated children should be excluded from school.
Children who receive their first MMR vaccine dose during an outbreak can return to school immediately.
Children exposed to measles should get vaccinated within 72 hours of exposure to stay in school.
If vaccinated later than 72 hours after exposure, children must stay home for 21 days.
Children who do not get vaccinated at all must stay home for 21 days after the last reported measles case in their community.

The Children’s Clinic in Jackson, TN, advises parents to speak with their pediatrician to determine when it is safe for their child to return to school while preventing further spread.

How to Prevent the Spread of Measles

Measles is highly preventable through vaccination. The MMR (measles, mumps, rubella) vaccine is 95% effective after one dose and 97–99% effective after two doses.

The recommended vaccination schedule includes:

First dose: 12–15 months of age
Second dose: 4–6 years of age
In outbreak situations, some children may need a third dose for extra protection.

If your child has been exposed to measles, contact their pediatrician immediately.
