LOS ANGELES (KABC) — Public health officials confirmed a third case of measles in a resident who recently traveled internationally and visited at least one public location in L.A. County while infectious.

The Los Angeles County Department of Public Health said the three cases reported in the past week are not related.

Individuals who visited the Mardi Gras Tuesday restaurant at 4543 Ventura Blvd. in Sherman Oaks between 11:30 a.m. and 2:30 p.m. on Jan. 24 may be at risk of developing measles.

Officials say people who were at the Mardi Gras Tuesday restaurant at that time may be at risk of developing measles seven to 21 days after being exposed and should monitor for symptoms. Anyone who remains symptom-free for more than 21 days after being exposed is no longer considered at risk.

For those exposed at Mardi Gras Tuesday, the last day to monitor for symptoms is Feb. 14.

The health department said flu activity is expected to remain high in the coming weeks.

Public health officials are working to identify any other potential exposure sites in Los Angeles County and anyone else who may be at risk of developing measles.

“Measles is a serious respiratory disease that spreads easily through the air and on surfaces, particularly among people who are not already protected from it,” Dr. Muntu Davis, the county’s health officer, said in a statement. “A person can spread the illness to others before they have symptoms, and it can take seven to 21 days for symptoms to show up after exposure. Measles can lead to severe disease in young children and vulnerable adults.”

“Measles is extremely contagious and can lead to serious complications, including pneumonia, brain swelling, and even death,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “With cases rising, it is critical that everyone ensures they are protected. The MMR vaccine remains the strongest and most effective way to protect yourself, your family, and your community. Before traveling, confirm your immunity and get the MMR vaccine if needed. It’s a simple step that makes a meaningful difference for your health and the health of those around you.”

Common symptoms of the virus are fever, cough, red watery eyes and a rash that usually starts on the head and spreads. The virus spreads through the air and by direct contact with an infected person. An infection can be spreading the virus for four days before the rash is noticed.
