Health District reports recent measles case in visitor to Clark County

FOR IMMEDIATE RELEASE:
December 23, 2025

LAS VEGAS — The Southern Nevada Health District is reporting a confirmed case of measles in an out-of-state visitor to Clark County. The individual traveled from out of state, and public health officials have identified the potential exposure window during the early morning hours on December 13, from 12:30 to 2:30 a.m. at Harry Reid International Airport.

The individual spent time near the D Gates, specifically Gate D1, for a flight arriving at around midnight. Due to the nature of airport travel and passenger movement, anyone who was in the D Gages area during this timeframe may have been exposed. No additional location details are available. The individual departed Las Vegas later the same day via private transportation.

Because measles is one of the most contagious respiratory diseases, people who may have been near the D Gates during that time, or who may have had contact with the individual while at the airport, should review their immunization records promptly. Anyone who is not fully vaccinated against measles or has not previously had the disease should contact their health care provider as soon as possible for guidance.

The measles virus can remain in the air for up to two hours after an infected person has left the area, meaning exposure can occur even without direct contact.

Measles symptoms can develop within seven to 21 days after exposure. Anyone who may have been exposed should monitor for symptoms and contact their health care provider if they develop a rash with fever or other symptoms consistent with measles. People who are experiencing symptoms should stay home, avoid public places and contact with others, and call ahead before visiting a health care facility so providers can take precautions and prevent further exposure.

Measles is a potentially serious disease. Symptoms include fever, cough, runny nose and red eyes. The characteristic rash typically appears one to four days after the initial symptoms. Measles can spread from about four days before the rash appears until four days after.

Complications can occur even in otherwise healthy people. Those at higher risk for severe illness include children younger than 5, adults older than 20, pregnant women, and people with weakened immune systems.

The measles, mumps and rubella (MMR) vaccine is safe and highly effective in preventing illness. Two doses of the vaccine provide approximately 97% protection against measles. Staying up to date on recommended vaccinations is the best way to protect individuals, families and the community from outbreaks of preventable diseases.

The Health District reported the first confirmed cases of measles in a Clark County resident since 2018 in November. An additional confirmed case in a visitor was reported in October. Measles cases and outbreaks continue to be reported across the United States.inunderscoring the importance of vaccination and rapid public health response.
