Virus shredding 06:47 - Jan 15 with 380 viewsurbanblue

Today I've read two articles of news where people who have tested positive for COVID19 are considered not to be contagious as the virus is 'shedding' although still in the body.

"We know you can shed for up to nine months when you're positive.'

'He then explained his first positive test was in November and he was now “totally recovered”. “I was sick in November, totally healthy now. There’s not a single documented case where I would be contagious at this point.”

The Australian Open suggested Victorian health authorities had given Sandgren the all-clear to fly.

The tournament’s official Twitter account said people who had recovered and were “non-infectious can continue to shed the virus for several months”.
