Let's look at what the scientific discipline tells u.s.a. so far.
How long does information technology take to get sick?
The "incubation period" is the fourth dimension between existence exposed to the virus and the onset of symptoms.

Commonly reported symptoms for COVID-19 – such as fever, cough and fatigue – usually last around nine to 10 days only this can exist longer.
Why are some people infectious for longer?
Typically with viruses, the higher the viral load (the more virus circulating in the body), the higher the risk of transmission through known transmission pathways.
A written report conducted in Hong Kong looking at viral load in 23 patients diagnosed with COVID-19 found higher viral loads in the first week of illness.
Some other study from China looking at 76 hospitalised patients found that by ten days after symptom onset, mild cases had cleared the virus. That is, no virus was detectable through testing.
However, astringent cases take much college viral loads and many continue to exam positive across the 10 days later symptoms start.
So the more astringent the illness and the higher the viral load, the longer you continue to shed the virus and are infectious.

One written report from Hong Kong establish the virus could be detected for xx days or longer later the initial onset of symptoms in one-3rd of patients tested.
Some other study from China found constitute the virus in a patients' faecal samples v weeks after the get-go onset of symptoms.
Simply the detection of the virus doesn't necessarily mean the person is infectious. Nosotros need more studies with larger sample sizes to get to the bottom of this question.

The requirements are different for people who have been diagnosed with COVID-19.
At present, re-testing people who take experienced mild illness, and have recovered from COVID-19 is not recommended. A person is considered prophylactic to render to the community and discontinue self-isolation if they are no longer infectious. This means they developed their outset symptoms more than x days prior and have not experienced any symptoms for at to the lowest degree 3 days (72 hours).
For people who take been hospitalised with more severe illness, the testing requirements earlier discharge are dissimilar. They will take two swabs taken 24 hours autonomously to check if they have cleared the virus. If the swabs are both negative, they can be discharged and don't require further self-isolation.
If i or both tests are positive but the person is well plenty to go home, they must continue to self-isolate for at to the lowest degree 10 days since they were discharged from hospital and they have not experienced whatsoever symptoms for at least 3 days.
There are likewise dissimilar testing requirements for people working or living in high-adventure settings. If y'all work or live in a high-risk setting you should consult with your wellness care provider on re-testing requirements.
