RNA copies/h shed into fine particle exhaled breath aerosols by Day‐EG (Vjk), by EG (Vk) from observed and imputed samples (number samples with at least 1 detectable qRT‐PCR replicate, number samples tested). Details about imputed sample estimation in the “Quantifying viral shedding in exhaled breath” subsection of the Section 2.
a
EGs with no Donors shedding any fine aerosols with at least one qRT‐PCR replicate positive (ND, not detected = 0/2 qRT‐PCR replicates detected, or no sample collected).
b
EG with the transmission event.
c
Not time weighted.
