and thanks for being with us on this Monday. I'm Raj Mathai and I'm Audrey Asistio. Santa Clara County health leaders are now working to alert dozens of people who may have been exposed to measles. They say the hyper contagious virus was brought into the county by someone visiting from out of state, as NBC Bay Area's Marianne Favro reports, they're specifically concerned about three places that person visited. Health leaders say after the infected person visited the Bay Area, they got on a flight at San Jose International Airport, potentially infecting more than 90 Santa Clara County residents on that flight. This Starbucks on Blossom Hill Road in Los Gatos is one of three places county health leaders say a person with highly contagious measles visited on July first, sometime between 930 and 1130 in the morning. The sick person then dined at Taqueria Los Pericos on Water Street in Santa Cruz from 6 to 10 p.m. the same day. Doctors say the next morning, the infected person headed to San Jose International and was there from 515 to 730 in the morning before catching a southwest flight to Chicago. Now, public health leaders are trying to reach more than 90 Santa Clara County residents on that flight who may have been exposed and warning anyone who visited those businesses that they should watch for symptoms. One of the challenges is that measles stays in the air. So even after a person with measles leaves a room or an area, the measles virus can stay in the air for up to an hour or more after that person has left, and they can still continue to infect the person, even though they're not even there. Doctor Monica Roy says it's important you take action if you think you've been exposed and the main things that they should be doing is one checking their immunization status, making sure that they have a vaccine against measles. Second, if they are pregnant, an infant or immunocompromised, or if they aren't vaccinated that they contact their health care provider immediately. Symptoms of measles include a red, blotchy rash, cough, runny nose, red eyes, nausea, vomiting, and diarrhea. If you have these symptoms, contact your doctor and isolate immediately. Doctor Roy says if you've had a measles vaccine, it offers very strong protection against the virus, but it is not foolproo
