Extended Data Figure 3.

To evaluate SARS-CoV-2 transmissibility via aerosols, one naïve hamster was exposed to one inoculated donor hamster in two adjacent stainless steel wired cages on 1 dpi for 8 hours. DietGel®76A (ClearH2O®) was provided to the hamsters during the 8-hour exposure. Exposure was done by holding the animals inside individually ventilated cages (IsoCage N, Techniplast) with 70 air changes per hour. Experiments were repeated with three pairs of donors: aerosol contact at 1:1 ratio. After exposure, the animals were single-housed in separate cages and were continued monitored for 14 days.
