A second person who travels through it Los Angeles International Airport has tested positively for measles.
The patient arrived on a flight from China Airlines on March 5 and was in Terminal B between 7 pm and 10:40 pm.
In the following days they then visited a nail salon in North Hollywood and a supermarket in El Monte.
Officials said that everyone who has visited any areas of exposure should immediately check their vaccination status.
Measles is the most contagious disease in the world, where one patient is able to infect nine out of 10 non -vaccinated people with which they come into contact.
However, the vaccine reduces the risk of developing the disease by 97 percent.
Los Angeles County health officials advised those who had not been vaccinated, but feared that they were exposed to check their symptoms for 21 days.
It marks the second measles patient to travel through Lax this year, after an infected baby arrived at the airport in February on a Korean air flight.

Three major American airports have already raised the alarm this year, where warnings are also issued in JFK International Airport in New York and Dulles International Airport from Washington DC.
It is also in the midst of a large outbreak of the disease in Texas, which has more than 250 people sick and has led to 29 hospital admissions and two deaths.
The infection is spread through breathing drops that are driven through cough and sneezing that can hang in the air for up to two hours.
Infected patients first suffer from fever, cough, runny nose and sore throat before they develop the characteristic red rash that starts on the face and spreads to the rest of the body, including the neck, trunk, arms, legs and feet.
After arriving on March 5, the local health authorities said that the patient visited Cloud 9 Nail Salon in North Hollywood between 11 am and 5 pm.
It is not clear whether the patient has been vaccinated.
On March 10, the patient went from 8.15 am to 10.30 am to the superior supermarket in El Monte.
It was not clear when the person first showed symptoms for measles or when their infection was diagnosed.
After the diagnosis of the disease, however, patients are told to insulate and if the symptoms become severe enough, they can be admitted to the hospital.
Patients are usually treated with painkillers, but can also receive antibiotics if they develop a corresponding infection or vitamin A if they show signs of malnourished.
In severe cases they may also need help.
Dr. Muntu Davis, the health officer of Los Angeles County, said: 'With outbreaks of measles that take place both in the United States and in international, this recent case emphasizes how important it is for anyone who is not immunized to get the measles, mumps and rubella (MMR) vaccin.
“Measles can easily spread through the air and on surfaces, and a person who is infected with measles can pass it on to others before they feel sick or have symptoms.”
She added: 'Young children and those who are pregnant or have weakened immune system run a higher risk of life -threatening complications of infection.
“Getting the MMR vaccine is the best way to protect yourself and to stop the spread of this dangerous disease.”
Two of the airport-linked measles that patients arrived in the US this year at China Airlines flights, while one has arrived at a Korean air flight.
The second case in Los Angeles is in a resident, while the first case was in a foreign traveler.
There are no reports that suggest an outbreak of measles in China or South Korea.
But at the end of last month, officials in Ontario, Canada also raised measles after an infected passenger arrived in the area from South Korea.
In contrast to the US, measles is not officially eradicated in China, which registers a low numbers of cases every year, but it was officially eradicated in South Korea in 2006.
The US reached the status of measles elimination in 2000, but since then there have been repeatedly emerging – linked to passengers who brought in the virus from abroad.
In recent years, however, the vaccination percentage against measles has fallen, in the midst of Covid vaccination mandates and worries about the safety of vaccines.
The measles vaccine is 97 percent effective against the virus, which can cause death or in some cases patients can leave a lifelong disability.
