Here, CDC Quarantine Public Health Officer, Diana Lu, assesses a sick traveler who has just arrived at the Los Angeles International Airport from another country.









Because of the COVID-19 pandemic, reducing the spread of respiratory illnesses, like flu, this fall and winter is more important than ever. CDC has worked with vaccine manufacturers to have extra flu vaccine available this flu season. Manufacturers have already begun distributing flu vaccine and will continue to distribute vaccine throughout the season. CDC recommends getting a flu vaccination in September or October but getting vaccinated anytime during the flu season can help protect you. Use the VaccineFinder to find out where to get vaccinated near you.​
