WASHINGTON, June 9, 2021 The World Health Organization and the Centers for Disease Control recommend keeping a certain distance between people to prevent the spread of COVID-19. These social distancing recommendations are estimated from a variety of studies, but further research about the precise mechanism of virus transport from one person to another is still needed.

Physics of Fluids, by AIP Publishing, researchers from Stony Brook University, Harvard, ETH Zurich, and Hanyang University demonstrate normal breathing indoors without a mask can transport saliva droplets capable of carrying virus particles to a distance of 2.2 meters, or 7.2 feet, in a matter of 90 seconds.

When Abigail S. Huebner â23 was deciding which concentration to declare in fall 2020, she was hesitant about declaring engineering without having ever taken an engineering course in person.
âI was confused about how I was going to sort of learn what engineering was and get a feel for engineering without having any in-person component, and without having the labs and hands-on experience that I know is usually so crucial to understanding engineering,â she said.
But since deciding to declare engineering as her concentration, Huebner said she has been âpleasantly surprisedâ by her experience in online engineering courses, though she acknowledged âthereâs still something missing.â
After the coronavirus crisis delayed the opening of Harvardâs new Science and Engineering Complex in Allston, faculty and staff at the School of Engineering and Applied Sciences have begun transitioning their offices to the new building.
Harvard had intended to open the complex, which has been under construction for roughly five years, this past summer. The coronavirus pandemic, which caused the City of Boston to impose a moratorium on construction projects in the spring of 2020 and has disrupted the Universityâs operations more broadly, forced Harvard to delay the opening of its new campus, into which Harvard poured roughly $1 billion.
