摘要：Equation 9 contains the variable
p
i
, which represents number of exposed persons. However, the text incorrectly defines
n
i
as the number of exposed persons. The text in the last sentence of the second paragraph of the “Methods” section that reads “Numbers of expelled virus particles in a ventilated room” should instead read “…and
p
i
is the number of exposed persons.”
The following text was added to the description of Equation 11 in the “Methods” section “Dose” for clarification: “The number
N
in Equation 11 represents the time-integrated numbers of expelled RNA copies of the virus and therefore has the dimension of time, and not the number of expelled RNA copies of the virus. Division of
N
as presented in Equation 11 by the exposure time
T
provides the numbers of expelled virus RNA copies.”
