“The crowded nature of things in an airport has always made me uncomfortable, particularly in a less modern one,” Fauci, the director of the National Institute of Allergy and Infectious Diseases (NIAID), recently told The New York Times. “People are literally nose to nose waiting to get on the plane.” Though airports and airlines have updated their guidelines to promote mandatory mask mandates and social distancing—such as spacing out boarding or blocking off middle seats—there’s still a long road ahead before it’ll be completely normal to travel again. According to Fauci, one of the best ways airports can become safer is to build more spacious terminals that allow people to spread out and hopefully curb the coronavirus as well as other respiratory illnesses. He also recommends that they offer free face masks and install HEPA filters, like those found in airplanes, which can remove 99.97 percent of microbes from the air. “You can’t throw up your hands and say it is impossible,” Fauci said. He adds that while it will be a difficult hurdle, especially with how many cases are asymptomatic, it’s worth trying extra health screenings, including temperature checks and contact tracing.
