Title: Temporal dynamics in viral shedding and transmissibility of COVID-19
  • Document date: 2020_3_18
  • ID: eflwztji_16
    Snippet: In conclusion, we found that viral shedding of laboratory-confirmed COVID-19 patients peaked on or before symptom onset, and a substantial proportion of transmission likely occurred before first symptoms in the index case. More inclusive criteria for contact tracing to capture potential transmission events 2-3 days before symptom onset should be urgently considered for effective control of the outbreak......
