Measles, Measles Symptoms and Treatments

What is measles (rubeola)?

Measles (rubeola) is a virus that is transferred through contact with someone who has the disease. The disease doesn’t usually cause long-term medical problems. However, it can cause serious and even deadly issues, particularly for children under the age of 5 and those with weakened immune systems.

Most people get over measles in about 10 days. The development of a skin rash is a hallmark symptom of the viral disease.

Being vaccinated is the best protection against the disease (see more below). The most common ways one can get measles are by being around someone with the disease – through talking, shaking hands, kissing, hugging or sharing food.

A highly contagious disease

A person also can get this viral illness without being near someone with the disease through infected droplets in the air from a person with the disease who talks, coughs or sneezes. These droplets of virus remain highly contagious for up to two hours after being transmitted.

Additional points about transmission & contagion:

  • A person can catch the disease by directly breathing in the virus droplet.
  • Transmission can also occur by touching a surface with an infected droplet then touching the mouth, nose or eyes.
  • Vertical transmission is when a pregnant woman passes the virus to her fetus or to her child through delivery or breastfeeding.
  • A person with measles is contagious from four days before until four days after the rash first appears.

Measles: a serious public health concern

Just about anyone can come into contact with the measles virus. Public transmission is how the disease most often spreads. Measles spreads in public places such as airports, tourist destinations, workplaces, schools and in dormitories. The Centers for Disease Control and Prevention (CDC) says that if a person with measles is in a room with 10 people not vaccinated, 9 out of 10 of them will get measles.

The CDC reports 1,319 confirmed United States cases as of July 19, 2025, with three deaths. About 13% of measles cases result in hospitalization.

Cases of the disease by age

  • 29% – under 5 years.
  • 37% – 5-19 years.
  • 34% – age 20 and above.
  • 1% – unknown age.

We strongly recommend the MMR vaccine

Due to consistent encouragement for people – especially children – to get the measles vaccine, the U.S. had eliminated this disease in 2000. This remarkable public health success was due to promotion by healthcare providers and parents of the vaccine, called MMR (mumps, measles, rubella) vaccine. Rubella means German measles, which is less common than the normal variety.

The MMRV (mumps, measles, rubella, varicella) vaccine is also effective in preventing the disease. Both types of vaccines require two doses for full protection.

For adults, vaccination is especially advised for high-risk groups if they lack evidence of immunity (e.g., health care workers, international travelers, women of childbearing age before they get pregnant, family caregivers of immunocompromised patients, students in post-secondary educational institutions). Persons born before 1957 are generally presumed immune (except for healthcare workers, who should be assessed for immune status).

Measles vaccine effectiveness

  • Before the vaccination was created in the early 1960s, about every child in the country got this viral illness, which caused up to 500 deaths a year.
  • Cases began to increase in 2008 mainly attributed to under- or unvaccinated populations.
  • The CDC reports that 1 in 5 unvaccinated people who have measles are hospitalized.

In spite of the success of the MMR vaccine, its use in the U.S. has declined in recent years mostly due to people’s growing distrust of vaccinations in general.

ID Care encourages all people to receive the measles vaccine. It is safe and effective.

Measles FAQ

What is measles?

Measles (rubeola) is a virus that is highly contagious with symptoms lasting about 10 days.

Is measles deadly?

Yes, this disease can lead to complications that cause death, particularly in young children, pregnant women and those with weakened immune systems.

How does measles spread?

Measles spreads through physical contact with someone who has the condition or by touching or breathing in viral droplets expelled by someone with the disease through talking, coughing or sneezing.

What causes measles?

The disease is caused by coming in contact with the measles virus (Morbillivirus), a single-stranded RNA virus that only affects humans.

How to prevent measles?

The only way to prevent this viral illness is with the MMR (mumps, measles, rubella) vaccine or the MMRV (mumps, measles, rubella, varicella) vaccine, usually administered in two doses.

Does vitamin A prevent or cure measles?

Vitamin A does not prevent or cure measles. It has only been shown to be potentially helpful in reducing complications in children who have already contracted the disease.

U.S. measles outbreak and measles in New Jersey

The year 2025 is a concerning time for measles containment. The CDC reports 29 outbreaks across the country as of July 2025. A majority of cases – 87% – this year are due to outbreaks, which is defined by CDC as 3 or more related cases.

Texas, primarily West Texas, is the hotspot for outbreaks, reporting 762 of the 1,319 cases in the country in July 2025. And 94% of the 762 confirmed cases were in people who were not vaccinated or their vaccination status is unknown.

Measles in New Jersey

In 2025 (up to the date of this page’s publication) the New Jersey Department of Health (NJDOH) reports that six cases of the disease have occurred in the state, with one other case under investigation. Three of those cases were part of a household outbreak in February.

In 2024 New Jersey had seven confirmed cases. NJDOH recommends that residents receive the MMR vaccine and are up to date on all vaccines. This is particularly true if travelling.

Know measles symptoms for quicker care

Measles symptoms will start to emerge about a week and a half after a person has come in contact with the measles virus. The first symptoms to appear will mimic the flu, with a cough, runny nose and possible fever. After a few days, Koplik’s spots (more on this symptom below) will develop then a rash appears.

Call your healthcare provider for advice if you suspect anyone in your family has the disease, including a red rash that looks like measles. Anyone who has this viral illness or suspects they do should isolate for four days after appearance of the rash.

Adults and children infected with measles will experience the following symptoms.

Fever, dry cough, runny nose, sore throat and red eyes

The first symptoms that are usually noticed are similar to flu symptoms. Fever can be as high as 105° Fahrenheit.

Koplik’s spots

Koplik’s spots (also called Koplik spots) are characterized by a blue-white center on a red background and can be found on the inner lining of the cheeks inside the mouth. They can show up 2-3 days after the symptoms above, though they are not always present in each case.

Skin rash (measles rash)

The rash associated with the disease is made up of large blotches that will run into each other. This skin rash, which becomes apparent about 3-4 days after initial symptoms, begins on the neck or face and spreads down the body, arms and legs.

Measles complications

Aside from the bothersome symptoms, the disease can cause other complications that can range from mild to life-threatening. These include:

  • Ear infection.
  • Bronchitis or laryngitis.
  • Dehydration.
  • Pneumonia.
  • Encephalitis (brain swelling).

While rare, patients with the disease can get subacute sclerosing panencephalitis (SSPE) and measles inclusion body encephalitis (MIBE). Both can occur after infection, even years later.

Measles risks

Those at increased risks for complications from the disease:

  • People with compromised immune systems.
  • Children under age 5.
  • Adults over age 20.
  • Pregnant women.

Diagnosis and measles treatments

The easiest way to diagnose a patient with this viral illness is by spotting the distinct rash and Koplik’s spots caused by the virus. However, the rash can be confused with other common illnesses.

Cases of the measles are still relatively rare in the U.S., so your doctor may want to take an extra step to confirm that you or your child are actually experiencing the disease. In that case, the physician will conduct a blood test to check for the presence of the virus.

Measles treatment

There are no broad treatments that are applied in every case, and measles cannot be cured. Our team of physicians will take into account the patient’s unique situation and develop a treatment plan that will be the most effective. Some common methods used to treat the measles follow.

Antibiotics

While antibiotics do not affect viruses, they combat common bacterial infections such as pneumonia and ear infections that often develop along with the condition.

Fever reducers

Over-the-counter medications like acetaminophen and ibuprofen can be given to reduce the intensity of fevers. People with the disease should not take aspirin, as a rare condition called Reye’s syndrome (also called Reye syndrome) may develop.

Post-exposure vaccination

If someone in your household has been exposed to the viral illness in the last 72 hours, administering the measles vaccine can help protect them against the virus if they have not already been immunized.
