Title: Temporal dynamics in viral shedding and transmissibility of COVID-19 Document date: 2020_3_18
ID: eflwztji_24
Snippet: We analyzed two separate data sets -clinical and epidemiologic -to assess presymptomatic infectiousness. First, we assessed longitudinal viral shedding data from laboratory-confirmed COVID-19 patients starting from symptom onsets, where viral shedding during the first few days after illness onset can be compared with the inferred infectiousness. Second, the serial intervals from clear transmission chains, combined with information on the incubati.....
Document: We analyzed two separate data sets -clinical and epidemiologic -to assess presymptomatic infectiousness. First, we assessed longitudinal viral shedding data from laboratory-confirmed COVID-19 patients starting from symptom onsets, where viral shedding during the first few days after illness onset can be compared with the inferred infectiousness. Second, the serial intervals from clear transmission chains, combined with information on the incubation period distribution, were used to infer the infectiousness profile as described below.
