Los Angeles County is currently at the center of a concerning public health alert. Officials have confirmed the first two measles cases of 2026, marking a critical moment amidst a nationwide resurgence of this highly contagious viral illness. These local cases, both linked to international travel, highlight the immediate need for residents to review their vaccination status and understand the risks. This developing situation underscores broader national trends, with the United States seeing an alarming spike in measles cases not witnessed in decades. Public health authorities are actively tracing contacts and identifying potential exposure sites across Southern California, including major travel hubs and popular public venues.
Urgent Measles Alert: LA County Confirms First Cases of 2026
The Los Angeles County Department of Public Health recently announced its initial two confirmed measles cases for the year 2026. This news comes as a stark reminder of measles’ persistent threat, especially given its prior elimination status in the U.S. These recent cases are part of a worrying national increase, emphasizing that vigilance and preventative measures are more crucial than ever.
The Source: International Travel Sparks Local Concern
Both confirmed individuals in Los Angeles County had a recent history of international travel. This connection highlights how easily diseases can cross borders in an interconnected world. The first case involved an LA County resident. Public health officials are working diligently to identify and notify anyone who may have come into contact with this individual, particularly within healthcare settings.
The second case involved an international traveler who passed through Los Angeles while infectious. This individual’s movements led to specific public exposure warnings, prompting immediate action from health authorities. Understanding the travel link is vital for residents, especially those planning international trips.
Public Exposure Sites Identified Across Southern California
The highly contagious nature of measles means even brief contact can lead to transmission. Public health officials have identified several locations where residents may have been exposed to the virus. These sites span across Los Angeles and Orange Counties, affecting thousands.
Key Exposure Locations in Los Angeles County:
Los Angeles International Airport (LAX) – Tom Bradley International Airport (TBIT), Terminal B: An infected traveler arrived on Viva Aerobus Flight #518 from Guadalajara, Mexico. Individuals present in Terminal B between 10:45 p.m. on January 26, 2026, and 1:00 a.m. on January 27, 2026, may have been exposed.
Dunkin’ Donuts, Woodland Hills: Located at 22020 Ventura Blvd. This same traveler also visited the Dunkin’ Donuts on January 30, 2026, between 3:00 p.m. and 4:45 p.m.
Important Exposure Sites in Orange County:
Disneyland Resort, Anaheim: An international traveler confirmed with measles visited several locations:
Goofy’s Kitchen, Disneyland Hotel: From 10:30 a.m. to 1:30 p.m. on January 28, 2026.
Disneyland Park & Disney California Adventure Park: From 12:30 p.m. until park closing on January 28, 2026.
EOS Gym, Ladera Ranch: On January 23, 2026, from 2:00 p.m. to 6:00 p.m.
AFC Urgent Care, Ladera Ranch: On January 23, 2026, from 3:30 p.m. to 6:00 p.m. and again on January 26, 2026, from 5:00 p.m. to 7:00 p.m.
Anyone present at these locations during the specified times should immediately review their vaccination status and monitor for symptoms. The incubation period for measles is typically 7 to 21 days after exposure.
Understanding the Measles Threat: Symptoms, Spread, and Severe Risks
Measles is far more serious than a common cold. Dr. Muntu Davis, Los Angeles County Health Officer, describes it as a respiratory disease that spreads easily. It travels through the air when an infected person breathes, talks, coughs, or sneezes. Alarmingly, the virus can remain airborne and viable on surfaces for several hours, contributing to its rapid spread.
How Measles Spreads and What to Look For
Infected individuals can transmit the virus even before showing any symptoms. This silent spread makes measles particularly dangerous in public settings. Initial symptoms often include a high fever (above 101 degrees Fahrenheit), a cough, a runny nose, and red, watery eyes. A distinctive rash usually appears a few days later, starting on the face before spreading across the body.
Dr. Joshua Partnow, an Emergency Room Physician with Dignity Health California Hospital, emphasizes that while measles is a virus, it carries life-threatening potential. It can lead to severe complications such as encephalitis (brain swelling) and pneumonia. Young children, infants, pregnant individuals, and those with weakened immune systems are particularly vulnerable to these serious health issues.
A National Resurgence: Why Measles Is Back
The local cases in Los Angeles County are not isolated incidents. They reflect a broader national and even international trend. The United States, which proudly achieved measles elimination status in 2000, is now experiencing a significant resurgence.
Alarming Statistics and Contributing Factors
As of January 30, 2026, a staggering 588 measles cases have been reported nationwide this year. This represents the highest number of reported cases for the month of January in over 26 years. The previous year, 2025, saw 2,242 confirmed measles cases in the U.S., the highest yearly total since the early 1990s. This surge is a sharp contrast to the 4,485 cases reported over the entire 24-year period from 2000 to 2024.
Experts link this concerning trend to declining vaccination rates. Dr. Partnow notes that measles, like polio, was once effectively controlled through widespread vaccination and herd immunity. He expresses disappointment that current resurgences are eroding these public health achievements. The article also points to “muddled vaccine messaging” in recent years, which may have contributed to lower vaccination uptake and the subsequent increase in vaccine-preventable diseases.
Protect Yourself and Your Loved Ones: Essential Public Health Recommendations
The good news is that measles is highly preventable through vaccination. The measles, mumps, and rubella (MMR) vaccine is incredibly effective, providing 97% protection with two doses. Public health officials are urging Angelenos to take proactive steps to protect themselves and their communities.
Actionable Steps for Los Angeles Residents:
Verify Immunization Status: Review your personal and family medical records. Ensure everyone has received the recommended two doses of the MMR vaccine or has confirmed immunity from a prior infection.
Inform Healthcare Providers if at Higher Risk: If you suspect exposure, or if you are pregnant, an infant, immunocompromised, or unvaccinated, contact your healthcare provider immediately. They can offer advice on preventative measures like immune globulin if exposure occurred less than seven days prior.
Monitor for Symptoms: Stay vigilant for symptoms like fever, cough, runny nose, red eyes, or rash for 7 to 21 days after potential exposure.
Seek Medical Advice Safely: If symptoms develop, stay home and avoid public gatherings. Crucially, call your healthcare provider before visiting any clinic or hospital. Inform them immediately about your possible measles exposure to prevent further spread within medical facilities.
Travel Smart: As summer travel approaches, and with cases increasing among travelers, ensure full vaccination protection, especially before international trips. Infants over six months old traveling internationally to outbreak areas can receive an early dose of the MMR vaccine.
Dr. Anissa Davis, Deputy County Health Officer, stresses, “The best way to protect yourself and your loved ones is to get vaccinated before exposure occurs.” This sentiment is echoed by Dr. Muntu Davis, who underscores the vaccine’s role in protecting families.
Public Health Collaboration and Ongoing Efforts
The Los Angeles County Department of Public Health is not working alone. They are collaborating closely with the Centers for Disease Control and Prevention (CDC), the Orange County Health Care Agency, and even officials at Disneyland. This coordinated effort aims to identify all potential contacts, notify individuals at risk, and contain the spread of the virus. The CDC routinely works with local health departments to investigate communicable disease exposures on international flights, ensuring a robust response system.
The department continues its investigation to identify any further potential exposure sites and assess risks within the community. For those exposed at LAX, the last day to monitor for symptoms is February 16, 2026. For those exposed at the Dunkin’ Donuts in Woodland Hills, it is February 20, 2026. If no symptoms appear after 21 days, the individual is no longer considered at risk from that specific exposure.
