  1. TSP, total suspended particles. The samples were distinct by design owing to the unique conditions inside the hospitals during COVID-19 outbreak. We collected 35 samples (not including two blanks) at different sites, therefore n = 35. The replicability is limited by very restricted experimental conditions to conduct sampling in the highly infectious zones.
  2. aTwo rounds of sampling were conducted for the sites. A blank control was included for each of round of sampling. Detailed information is shown in Supplementary Table 1.
  3. bThe samples were taken during the first round of sampling from 17 February to 24 February 2020.
  4. cThe samples were taken during the second round of sampling on 2 March 2020.
  5. dThe reported values are virus aerosol deposition rates in copies m−2 h−1.
