Coronavirus Outbreak: How long can you be infectious once you get infected?

Firstpost  

The incubation period for coronavirus is the time between someone being exposed to the virus and the onset of symptoms. For COVID-19, there is emerging evidence to suggest the infectious period may start 1 to 3 days before you develop symptoms. However, severe cases have much higher viral loads and many continue to test positive beyond the 10 days after symptoms start. If someone has been symptom-free for 3 days and they developed their first symptoms more than 10 days prior, they are no longer considered to be infectious. One study from Hong Kong found the virus could be detected for 20 days or longer after the initial onset of symptoms in one-third of patients tested.
