As of January 14, 2026, the United States is experiencing a resurgence of measles, with significant outbreaks reported in South carolina and along the Arizona-Utah border. Health officials are closely monitoring the situation and emphasizing the importance of vaccination to prevent further spread.
Measles Outbreaks: Current Situation (January 2026)
Health officials in South Carolina have confirmed a substantial increase in measles cases, reporting 124 new infections since Friday in the northwestern part of the state.This outbreak is linked to increased transmission following the holiday season, indicating a potential for continued spread if preventative measures aren’t taken.

Simultaneously, a separate outbreak is unfolding along the Arizona-Utah border, with a cumulative total of 418 confirmed cases since August. This geographically distinct outbreak highlights the challenges in containing the virus and the need for coordinated public health responses across state lines.
2023: The Worst Year for Measles in Decades
The current outbreaks build upon a concerning trend established in 2023, which was the worst year for measles spread in the United States since 1991.The Centers for Disease Control and Prevention (CDC) reported 2,144 confirmed cases across 44 states last year.associated Press Tragically, three deaths were attributed to measles in 2023, and all of the individuals who died were unvaccinated.
why is Measles Making a Comeback?
The resurgence of measles is largely attributed to declining vaccination rates. Measles, mumps, and rubella (MMR) vaccines are highly effective in preventing the disease, but coverage rates have fallen below the 95% threshold needed to maintain herd immunity. Factors contributing to this decline include vaccine hesitancy, misinformation, and disruptions in healthcare access.
Understanding Measles: Transmission, Symptoms, and Prevention
Measles is a highly contagious viral infection that spreads through the air when an infected person coughs, sneezes, or breathes. The virus can remain airborne for up to two hours in enclosed spaces, making it exceptionally easy to transmit.
Symptoms of Measles
Initial symptoms of measles typically appear 10-14 days after exposure and include:
- High fever (often exceeding 104°F)
- Cough
- runny nose
- Red, watery eyes (conjunctivitis)
- Small white spots inside the mouth (Koplik’s spots)
- A characteristic rash that spreads from the face to the rest of the body
Preventing Measles: The Power of Vaccination
The most effective way to prevent measles is through vaccination with the MMR vaccine. The CDC recommends that:
- Children receive two doses of the MMR vaccine: the first at 12-15 months of age and the second at 4-6 years of age.
- Adults who have not had measles or been vaccinated should receive two doses of the MMR vaccine.
- Individuals traveling internationally should ensure they are up-to-date on their MMR vaccinations.
The MMR vaccine is safe and effective, and it provides long-lasting protection against measles, mumps, and rubella. Centers for Disease Control and Prevention
The Risk of losing Elimination Status
Measles was declared eliminated from the United States in 2000, meaning that sustained transmission of the virus had been stopped. However, the recent outbreaks raise concerns that the U.S. could lose it’s elimination status, similar to what has happened in Canada. associated Press Re-establishment of endemic measles transmission would pose a significant public health threat, leading to increased illness, hospitalizations, and potential complications.
Key Takeaways
- Measles outbreaks are occurring in South Carolina and along the Arizona-Utah border.
- 2023 saw the highest number of measles cases in the U.S. since 1991.
- declining vaccination rates are a primary driver of the resurgence.
- the MMR vaccine is highly effective in preventing measles.
- The U.S. is at risk of losing its measles elimination status.
Public health officials urge everyone to review their vaccination records and ensure they are up-to-date on the MMR vaccine. Protecting yourself and your community from measles requires a collective effort to maintain high vaccination coverage rates.
