When was the last reported measles infection in Utah?

The last reported measles infection in Utah was in March of 2023. A person who was not vaccinated traveled outside the U.S. and brought measles back to Utah. We don't believe anyone else in Utah got measles from this person.

Before that, there were 3 people in Utah who had measles in February 2017. The first person who had measles was a young child who had traveled internationally to an area where measles was spreading. The child was not up-to-date on vaccinations. The child had contact with many people, including at church gatherings, family events, and multiple medical visits when they returned to Utah. Two people who were not vaccinated for measles and had contact with the child became infected with measles.

Has anyone been exposed somewhere else and come to Utah?

We don’t know. There have been no reports of anyone with measles in Utah, but we are keeping a close eye on the situation.

Do you need to get a booster shot because measles is spreading in other states?

Not if you are up-to-date with your measles vaccinations. Most people born after 1957 need 2 doses of the MMR vaccine to be fully protected against measles.

Talk to a healthcare provider about getting another dose of the MMR vaccine if you were born after 1957 or vaccinated before 1968. The majority of people born before 1957 are likely to have been infected with measles and therefore are presumed to be protected. An older type of vaccine was used between 1963 and 1967 but it did not provide immunity that lasted very long. Anyone who got a measles vaccine between 1963 and 1967 is considered unvaccinated. These people should get a MMR shot. 

We recommend everyone make sure you are protected against measles.

You are considered to be protected against measles if at least 1 of the following applies to you:

  • You have a written record of your vaccine history and it shows you are up-to-date on the number of doses you need for your age.
    • You are considered up-to-date with 1 dose of MMR vaccine if you are:
      • Preschool aged (older than 12 months but not in kindergarten yet).
      • An adult who is NOT in high school, college, or another post-high school educational institution, NOT a healthcare worker, and NOT traveling internationally or to a place with an active measles travel advisory.
      • Age 6 to 12 months AND traveling internationally or to a place with an active measles travel advisory.
    • You are considered up-to date with 2 doses of MMR vaccine (separated by 28 days) if you are:
      • In kindergarten through grade 12.
      • Attending college or another post-high school educational institution.
      • A healthcare worker.
      • Older than 12 months AND traveling internationally or to a place with an active measles travel advisory.
  • You have lab results that show enough measles antibodies in your blood (laboratory evidence of immunity).
  • You have lab results that show you have had a measles infection in the past.
    • Verbal history of measles does not count.
  • You were born before 1957 (people born before 1957 have most likely had measles in the past and are considered immune).

Talk to a doctor if you have questions about whether you are protected against measles.

    Measles overview

    Image
    Symptoms
    • High fever (may get higher than 104°F or 40°C).
    • Cough
    • Runny nose
    • Red, watery eyes
    • Tiny white spots in the mouth (Koplik spots)
    • Rash (Measles rash usually begins as flat red spots on the face at the hairline. The spots then spread down to the neck, belly, arms, legs, and feet.)

    Complications
    • Pneumonia (a serious lung infection)
    • Hospitalization
    • Encephalitis or brain swelling (can cause cognitive disability, deafness, and seizures)
    • Complications during pregnancy, such as the risk of premature labor (having your baby early), miscarriage, and your baby having a low birth weight
    • Seizures
    • Weakened immune system that can last weeks to years (increases the risk of bacterial infection and infection from other diseases)
    • Death

    When symptoms usually start (onset)

    The first symptoms of measles start between 1 and 3 weeks after you are infected with the virus. Most people have symptoms at about 2 weeks.


    How long it lasts (duration)

    The first symptoms (fever, cough, runny nose, watery eyes) last for about 2 to 4 days but can be as short as 1 day or as long as 8 days. Some people get tiny white spots inside their mouth (called Koplik spots). Koplik spots may appear before the measles rash.

    The rash normally lasts 5 to 7 days and begins about 3 to 5 days after the first symptoms start.


    Causes

    Measles virus


    How to prevent measles
    • 2 doses of the MMR vaccine (measles, mumps, rubella), or
    • 2 doses of the MMRV vaccine (measles, mumps, rubella, varicella)

    Treatment

    There's no specific treatment for a measles infection once it occurs. Treatment includes providing comfort measures to relieve symptoms, such as rest, and treating or preventing complications
