Health officials in Los Angeles County have issued an urgent warning following the confirmation of multiple measles cases in late January and early February 2026. The cases have been linked to international travel and have prompted public alerts regarding high-traffic locations that may have been exposed to the virus. Authorities are advising residents to check their vaccination status and monitor for symptoms, particularly after measles exposure sites were identified at Los Angeles International Airport (LAX), Disneyland, and other popular locations.
Measles, a highly contagious disease, spreads easily in crowded environments, raising concerns about its potential for rapid transmission in places with heavy foot traffic. Los Angeles County Department of Public Health (LACDPH) is actively working to identify and notify anyone who may have been exposed to the virus, urging individuals to take appropriate precautions.
Exposure Sites Linked to Measles Infections
The first confirmed measles case in Los Angeles was reported on January 30, 2026, involving a resident who had recently traveled internationally. A second case was linked to a traveler who visited Los Angeles International Airport, specifically Terminal B, on January 26, 2026. Additional exposure sites include Disneyland Resort, Goofy’s Kitchen, and a Dunkin’ Donuts location in Woodland Hills.
Health officials emphasize that measles is highly contagious and can linger in the air for up to two hours after an infected person leaves a space. Given the high volume of people at locations like LAX and Disneyland, the risk of transmission in these areas is a significant concern. Residents who visited these exposure sites during the specified times are encouraged to verify their vaccination records and be vigilant for symptoms.
Symptoms and Risks of Measles
Measles typically begins with high fever, cough, runny nose, and red, watery eyes, followed by the appearance of a rash several days later, starting on the face and spreading downward. Symptoms generally develop between 7 to 14 days after exposure.
While most people recover from measles without serious complications, the disease can lead to more severe health issues such as pneumonia and encephalitis (brain inflammation). Infants, pregnant women, and individuals with weakened immune systems are at a heightened risk for complications. Health officials are urging anyone who suspects they may have been exposed to seek medical care promptly and to avoid public spaces until cleared by a healthcare provider.
In response to the recent measles cases, Los Angeles County Department of Public Health has issued advisories for residents who may have been exposed at the identified locations. Direct notifications were sent to healthcare providers and facilities where infected individuals sought treatment, ensuring that those who came in contact with the patients are informed.
The department is actively reminding residents to check their vaccination records and get vaccinated if necessary. The measles, mumps, and rubella (MMR) vaccine remains the most effective way to prevent the disease and protect against its spread. Health officials are also stressing the importance of herd immunity, which occurs when a large portion of the population is vaccinated, protecting vulnerable individuals who cannot receive the vaccine.
Rising Measles Cases Across the Nation
The measles outbreak in Los Angeles is part of a national trend that has seen an increase in cases across the U.S. in recent years. Measles outbreaks have been reported in several states, with 2025 and 2026 showing particularly high levels of transmission. Public health experts point to international travel as a key factor in the spread of the virus, as it remains prevalent in parts of Europe, Asia, and Africa.
California, a major international travel hub, faces increased risk due to its large number of visitors and travelers passing through airports and popular tourist destinations. Health officials are urging all travelers to ensure their vaccinations are up-to-date before traveling internationally, to help curb the potential spread of measles.
Health experts emphasize that the MMR vaccine is the most effective way to protect against measles. Individuals who are unsure of their vaccination status are encouraged to check with their healthcare provider and receive the vaccine if needed. The MMR vaccine is widely available and is recommended for children and adults who have not yet been vaccinated.
Those who may have been exposed to measles should monitor for symptoms for up to 21 days after exposure. If symptoms develop, individuals are urged to seek medical attention promptly and avoid public gatherings to prevent further spread.
Los Angeles Continues to Monitor the Situation
As measles cases continue to be monitored, Los Angeles health officials are staying vigilant and preparing to address any further cases. The Los Angeles County Department of Public Health will continue to update the public and respond to any new potential exposures.
For now, officials are encouraging residents to remain aware and take preventive steps by checking their vaccination status, seeking timely medical care, and following guidelines from health authorities. The current situation highlights the ongoing need for global and local health preparedness, especially in areas with high international traffic and dense populations.
