The Louisiana Department of Health (LDH) has confirmed the first case of measles in the state for 2025. The case, reported in Region 1—which includes the Greater New Orleans area—involves an adult resident who was not fully vaccinated and is believed to have contracted the disease while traveling internationally.
This development has prompted an urgent advisory from health officials, who are working swiftly to identify potential exposures and educate the public on the importance of measles prevention.
What We Know About the Confirmed Measles Case in New Orleans
According to LDH’s official press release, the infected individual began showing symptoms after returning from international travel. While no additional cases have been reported, the Department of Health is conducting a full epidemiological investigation, tracing contacts and notifying individuals who may have been exposed.
The case underscores a growing concern among public health professionals about the re-emergence of measles in the United States—a disease that was declared eliminated nationally in 2000 but has resurfaced due to vaccine hesitancy and increased global travel.
What Are the Symptoms of Measles?
Measles is a highly contagious viral illness that begins with symptoms resembling a common cold:
- High fever
- Cough
- Runny nose
- Red, watery eyes (conjunctivitis)
These are typically followed by a rash that spreads across the body. The virus is so contagious that if one person has it, up to 90% of the people around them who are not immune will also become infected, according to the Centers for Disease Control and Prevention (CDC).
Complications can be severe, including pneumonia, encephalitis (swelling of the brain), permanent hearing loss, and even death, especially among young children and immunocompromised individuals.
How the Virus Spreads
The measles virus is airborne and can linger in the air for up to two hours after an infected person coughs or sneezes. Individuals can spread the virus up to four days before and after the rash appears. Because of this, even brief encounters in public places like airports, stores, or medical offices can lead to exposure.
Vaccination: The Most Effective Defense
Health officials are urging residents across Louisiana—and especially in New Orleans—to check their vaccination records. The MMR vaccine (measles, mumps, rubella) is approximately 97% effective after two doses.
Children should receive their first dose at 12–15 months of age and the second dose at 4–6 years. Adults who are unsure of their immunization status are encouraged to speak with their healthcare providers, especially before traveling internationally.
In a statement, State Health Officer Dr. Joseph Kanter emphasized,
“This case is a stark reminder of the importance of staying up to date on vaccinations. Measles is highly contagious and can be extremely dangerous, but it is preventable with a safe and effective vaccine.”
What You Should Do If You Suspect Exposure
If you or someone in your household is experiencing symptoms consistent with measles, health experts advise:
- Stay home and avoid public places.
- Call your healthcare provider before visiting to prevent potential spread.
- Notify others you may have come into close contact with.
Early detection can help prevent an outbreak and limit community transmission.
The Bigger Picture: A National Resurgence
The New Orleans case comes amid a nationwide uptick in measles reports. As of mid-April 2025, the CDC has recorded over 120 measles cases in 17 states, the highest count in nearly five years. Most outbreaks are linked to unvaccinated travelers who bring the virus back to the U.S. from countries where measles remains endemic.
Public health agencies are emphasizing that community-wide immunity—also known as herd immunity—requires at least 95% of the population to be vaccinated. Any gaps in coverage, especially in densely populated areas like New Orleans, can result in fast-moving outbreaks.
Key Takeaways for New Orleans Residents
- One confirmed measles case has been reported in the Greater New Orleans area as of April 2025.
- The infected individual was unvaccinated and contracted the virus abroad.
- Vaccination is your best defense. Two doses of the MMR vaccine offer nearly complete protection.
- If you think you’ve been exposed or have symptoms, contact your doctor immediately and avoid public areas.
