Measles Cases Surge in the US: What You Need to Know Now

The United States is witnessing a dramatic increase in measles cases, with a reported **171 cases** in just the first two weeks of **2026**. This figure, highlighted in data released by the **US Centers for Disease Control and Prevention** (CDC), is nearly equivalent to the average annual total recorded over the past 25 years since measles was declared eliminated. The majority of new cases are concentrated in areas experiencing significant outbreaks, particularly in **upstate South Carolina** and along the **Utah-Arizona** state line, raising concerns about broader public health risks.

As measles spreads, tracking every potential exposure becomes increasingly difficult. According to **Dr. Linda Bell**, South Carolina’s state epidemiologist, individuals may unknowingly interact with others while infectious. Recent public exposure sites have included schools, restaurants, and health care settings, although not all exposure locations are disclosed unless specific details can be confirmed.

In addition to local outbreaks, there have been instances of potential exposures linked to travel. In **New Mexico**, health officials warned of possible exposure at a hotel in **Albuquerque** from a visitor returning from South Carolina. Furthermore, significant travel hubs such as major international airports reported cases or potential exposures during the peak holiday season.

Vaccination remains the most effective defense against measles. **Dr. Jesse Hackell**, a retired pediatrician and member of the American Academy of Pediatrics, emphasizes that the **measles-mumps-rubella (MMR)** vaccine significantly reduces the risk of exposure leading to disease. One dose of the vaccine is **93% effective** against measles, while two doses increase that protection to **97%**. Vaccination is especially important as the number of cases continues to rise, further complicating public health efforts.

What to Do If You’ve Been Exposed

If you believe you have been exposed to measles, the first step is to check your vaccination status. The MMR vaccine is generally recommended for children at **12 to 15 months** of age, with a second dose administered between ages **4 and 6**. In outbreak situations, the first dose may be given as early as **6 months**. For those who have been vaccinated, experts suggest monitoring for symptoms rather than panic, as vaccination typically provides robust protection.

For unvaccinated individuals who suspect exposure, acting swiftly is crucial. The MMR vaccine can still provide some protection if administered within **72 hours** of exposure. **Dr. Raynard Washington**, director of the public health department in **Mecklenburg County**, North Carolina, advises those who suspect exposure to contact their health care provider before visiting medical facilities to prevent further spread.

Recognizing Symptoms and Staying Informed

Measles symptoms can initially resemble other respiratory illnesses, starting with a fever, cough, and runny nose. The characteristic rash appears a few days later, beginning in the mouth and moving down the body. An early sign that may indicate measles rather than another virus is conjunctivitis, or pink eye.

There is no specific treatment for measles, making vigilance essential. Regular check-ins with health care providers can help manage symptoms and monitor for complications. Hospitalization may be required if severe symptoms, such as pneumonia or encephalitis, develop.

Awareness of local vaccination rates is important for families. An outbreak in a school with a high vaccination rate poses less risk than one in a school with lower coverage. Public health officials stress the importance of monitoring potential exposures in various communal settings, including airports and public transport.

In **South Carolina**, over **400 individuals** are currently in quarantine following known exposures, underscoring the importance of public health measures to contain outbreaks. Vaccinated individuals do not need to quarantine, providing peace of mind during such health crises.

Local public health departments are actively monitoring the situation and issuing regular updates. For instance, Mecklenburg County officials recently reported detecting measles in wastewater, indicating a recent infection in the area. This information prompted immediate public health responses, including vaccination availability at local clinics.

As the measles outbreak unfolds, proactive measures, including vaccination and staying informed, remain crucial in preventing further spread of this highly contagious disease.
