Los Angeles County health officials are urging residents to ensure they are protected against measles following a fourth confirmed case this year, as the highly contagious virus continues to spread nationally. The latest case involves a county resident who recently traveled internationally and visited several public locations while infectious, raising concerns about potential exposure for others.
The individual arrived at Los Angeles International Airport (LAX) on February 9 aboard Singapore Airlines Flight 38, landing at approximately 7 p.m. After a 14-hour journey, according to the Los Angeles County Department of Public Health. Public health officials are particularly focused on potential exposures at the Tom Bradley International Terminal (Terminal B) between 7:30 p.m. And 9:40 p.m. That evening. Passengers seated near the infected traveler will be notified by their local health departments, in collaboration with the Centers for Disease Control and Prevention (CDC).
Beyond the airport, the infected individual visited several prompt-food restaurants in the San Gabriel Valley, potentially exposing members of the public. These locations include a Burger King in Montebello (1212 West Beverly Blvd.) on February 10 between 5:30 p.m. And 7 p.m., Taqueria El Atacor in Whittier (11156 1/2 Whittier Blvd.) on February 11 between 3 p.m. And 5 p.m., Domino’s Pizza in Montebello (803 West Whittier Blvd.) on February 12 between 4 p.m. And 5:15 p.m., and a 7-Eleven in Montebello (1106 West Beverly Blvd.) on February 13 between 4:30 p.m. And 5:45 p.m.
Rising Cases and Vaccination Importance
This latest case comes amid a nationwide increase in measles infections. According to the CDC, there were 2,280 confirmed cases in the U.S. Last year, the highest total since 1991. As of February 12, 910 cases had already been confirmed nationwide in 2026, including 15 in California. The rise in cases is linked to declining vaccination rates, allowing the virus to spread more easily in communities with lower immunity levels.
“As measles cases increase, it is critical that residents take steps to make sure they are fully protected,” said L.A. County Health Officer Dr. Muntu Davis in a statement. “The [measles-mumps-rubella] vaccine is the safest and most reliable way to prevent measles and protect yourself, your family, and your community.”
Symptoms and What to Do If Exposed
Symptoms of measles typically develop between seven and 21 days after exposure and can include fever, cough, runny nose, red eyes, and a rash. Individuals who believe they may have been exposed are urged to confirm their immunity status, either through vaccination records or a history of prior infection.
Those who are not immunized or are unsure of their status should closely monitor themselves for symptoms. If symptoms develop, individuals are advised to stay home, avoid contact with others, and contact their healthcare provider immediately – but to call ahead before visiting any medical facility. The health department has established symptom monitoring deadlines: March 2 for those potentially exposed at LAX, and March 6 for those who visited the 7-Eleven in Montebello.
Previous Cases in L.A. County This Year
This is the fourth measles case confirmed in Los Angeles County in 2026. Previous cases involved individuals who as well recently traveled internationally. One case involved a visit to Sherman Oaks on January 24, while another involved exposure in Woodland Hills on January 30. The first case of the year had no identified public exposure locations within the county.
Health officials emphasize that the MMR vaccine is highly effective in preventing measles. Children age 1 year and older are considered fully immunized after receiving two doses. “Measles spreads easily and can lead to serious complications, including pneumonia, brain swelling, and even death,” Dr. Davis warned. “We urge everyone to confirm their immunity and get the MMR vaccine if needed, especially before traveling. Taking this simple step helps safeguard your health and strengthens protection for our entire community.”
