In conclusions, our SARS-CoV-2 RNA loads measures in upper respiratory tract samples revealed that asymptomatic outpatients shed significant levels of infectious virus in their respiratory tract playing a major role as viral transmitters in various epidemiological transmission chains, promoting COVID-19 resurgence.

Results The baseline assumptions for the model were that peak infectiousness occurred at the median of symptom onset and that 30% of individuals with infection never develop symptoms and are 75% as infectious as those who do develop symptoms. Combined, these baseline assumptions imply that persons with infection who never develop symptoms may account for approximately 24% of all transmission. In this base case, 59% of all transmission came from asymptomatic transmission, comprising 35% from presymptomatic individuals and 24% from individuals who never develop symptoms. Under a broad range of values for each of these assumptions, at least 50% of new SARS-CoV-2 infections was estimated to have originated from exposure to individuals with infection but without symptoms.
