Individuals are infectious with COVID-19 when they’re shedding the virus, which means that the virus replicates in the cells of their upper or lower respiratory tract. In this video, we will examine published articles discussing viral shedding, the incubation period (mean incubation period was 5.2 days) and the serial interval, by examining the results of 77 COVID-19 transmission pairs.
The study found that infectiousness starts 2.3 days before symptom onset. That patients are most infectious 0.7 days before symptom onset.They also found that 44% of infectiousness or infections occurred in the pre-symptomatic phase making it difficult to track.
