Measles have become a significant problem over the past few months. Extensive media coverage and online discourse have left many confused: why are there suddenly outbreaks? Why are infections in children skyrocketing? Is there any way I can prevent the spread of measles?

This Comprehensive Guide covers measles using information from top medical sites and journals, allowing you to understand exactly what measles is, the symptoms and progression, what to do if you have been exposed, common misconceptions, the importance of public health safety, and how to help your community understand the urgency regarding measles.

What is Measles?

Measles, also referred to as rubeola, is a highly contagious viral infection that primarily affects young, unvaccinated children, but can infect unvaccinated adults (or adults who did not build immunity from a previous infection).

Measles is an airborne disease, meaning it spreads when an infected person breathes, coughs, sneezes, or talks. Droplets can infect surfaces and objects for up to two hours. People can become infected by inhaling droplets, being in close proximity to an infected person (touching, sharing food, etc.), and touching an infected surface and then touching the eyes, nose, or mouth.

Many outbreaks started due to a decrease in vaccination rates.

What Are Measles Symptoms and Complications?

Symptoms:

Measles symptoms are generally consistent among children and adults. The symptoms listed below do not develop at the same time. Symptoms usually emerge around 7-14 days after the initial contact with measles.

Infected, but fully-vaccinated individuals’ symptoms tend to be mild, and are not contagious.

According to the CDC, the Cleveland Clinic, and the Mayo Clinic symptoms of measles include:

• Headache
• High fever (may be as high as 105 degrees Fahrenheit)
• Red or bloodshot eyes
• Red, watery eyes (conjunctivitis)
• Red spots with white centers in your mouth (Koplik’s Spots)
• Sore throat
• Dry cough
• Runny nose
• Fatigue
• Muscle pain
• Stomach pain
• Rash

Complications:

In severe cases, complications can occur, especially in children younger than five. These include:

• Ear infections
• Diarrhea
• Pneumonia
• Bronchitis
• Encephalitis (inflammation of the brain)
• Subacute sclerosing panencephalitis – very rare, fatal nervous system disease

How is Measles Diagnosed?

Measles is usually diagnosed by healthcare providers through clinical symptoms, such as a rash, Koplik spots, and conjunctivitis. The patient and family history will be examined for any past infections, vaccinations, and recent travels (domestic and international).

Lab testing is required to confirm if a person has measles as it is not a common illness. Your healthcare provider will most likely collect swab samples from your nose or throat, but may ask for a urine or blood sample.

What is the Infection Timing and Treatment?

According to Minnesota Health, symptoms begin to show around 7-14 days after the initial infection. Around 2-3 days after, Kolpik spots form in the mouth. Around 3-5 days after, or 14 days after the initial infection, a rash will begin to form on the face and neck before possibly spreading down to the chest and arms. The rash can have large, flat spots and/or small, raised bumps.

There are no asymptomatic infectious carriers.

The contagious period is from 4 days before to 4 days after the rash onset. The incubation period lasts around 10-12 days from the initial exposure to the first symptoms, and 14 days (range 7-21) from the initial exposure to the rash onset.

Measles usually lasts around 10-14 days, but timing can vary. Recovery usually begins between 10-14 days, and most feel better after 2-3 weeks. However, some complications can last longer.

There is no specific cure or treatment for measles. Instead, measles is treated by managing symptoms and reducing the risk of complications. Healthcare providers may prescribe Vitamin A to support the immune system. Do not take Vitamin A without a doctor’s supervision or prescription — Vitamin A toxicity can cause organ damage.

Who is at Risk?

Children who are unvaccinated or have received only one dose of the measles vaccine (MMR) are most at risk. People with weakened immune systems, pregnant women, and frequent travelers are at a significant risk of infection.

How Can I Prevent Measles?

You can prevent exposure and infection in one major way: vaccination. The best way to protect yourself and others is with the measles, mumps, and rubella (MMR) vaccine.

According to the Cleveland Clinic, “On average, the vaccine gives lifelong protection from measles for about 97% of people who get two doses of the vaccine”.

For people who have received one dose, that percentage drops to 93%. Before getting vaccinated, talk to your healthcare provider. They will examine your medical history (pre-existing conditions, allergies, seizures, etc.) and discuss available options. Do not get the measles vaccine if you’re pregnant or have a severely weakened immune system. This is to prevent any further possible complications. Children and adults can get the vaccine.

General ways to prevent infection and illness are to keep spaces clean, avoid places with cases, and stay updated on any outbreaks in your town or city. 

In some cases, children may need another vaccine. Infection could take away immunity, and children are more likely to get infected despite prior recovery.

What Do I Do If I Was Exposed to Measles?

If you believe that you have been exposed to measles, notify your healthcare provider immediately. Your healthcare provider will organize a way to collect samples and conduct tests without putting others at risk. If you are unvaccinated, you may be advised to stay home in quarantine for 21 days.

Common Misconceptions About Measles:

• The MMR Vaccine causes autism

This claim is false. The MMR Vaccine has no connection to autism later in life. This claim has been debunked many times by scientists and medical professionals. This misconception began with a 1998 medical paper connecting the MMR Vaccine to autism. The paper was declared fraudulent as the data lacked key points that were necessary in a traditional study.

• The MMR Vaccine is not effective

This claim is false. The two-dose MMR vaccine is 97% effective in preventing measles and provides immunity to infection and transmission.

• Vitamin A is dangerous

This claim is partially true, but misleading. Vitamin A can improve patient recovery because it boosts the immune system. However, excessive consumption can cause Vitamin A toxicity leading to organ damage and adverse side effects. Do not take Vitamin A on your own. Consult with a medical professional and follow their supplement prescription.

• Measles is a common illness

This claim is false. In the United States, measles had essentially been wiped out.

What Can I Do For The Community?

The most important thing you can do is advocate for vaccination and support nationwide vaccination efforts. As of May 2025, Texas is experiencing the worst outbreaks with over 722 confirmed cases. Petitions are a great way to voice your beliefs. Lets protect our community and in turn, our state and country.

The Importance of Public Health Safety

Public health safety protects the well-being of a community by preventing the spread of disease and promoting healthy habits like good hygiene. It also ensures people are aware of symptoms and risks. Every effort to address public health issues, improve sanitation, and educate the general public about measles is crucial in keeping everyone. In times of crisis, such as outbreaks, effective public health minimizes the impact on those vulnerable to infection and illness.
