I’ve seen some studies that indicate that a person with a mild case of COVID is not contagious for more than 10 days and that the 14 day quarantine is overkill:
Citing multiple studies by the agency and beyond, the CDC found those who have mild cases of COVID-19 may not have to be in quarantine for 14 days, that duration potentially being shortened to 10.
Scientists found 10 days after onset symptoms, patients they studied did not have "replication-competent virus" — or in simpler terms, virus which could infect cells and replicate.
I-5 wrote:What I’d like to know more about is if this takes into account what kind of drugs or steroids helped decrease the symptoms...for example when I have a flu I take meds to feel better and lessen my symptoms, but during the incubation period I’m still contagious even if I’m not feeling symptoms (due partially to meds). Trump is the perfect example. He’s probably walking around with the best cocktail of covid drugs the world has ever known, probably without a mask on, and according to his doctor he’s ‘asymptomatic’. Would you feel comfortable shaking his hand?
I think the answer to your question may be the 2nd paragraph of the quote:
patients they studied did not have "replication-competent virus" — or in simpler terms, virus which could infect cells and replicate.They're not looking at symptoms, they're looking at the
"replication-competent virus" that could infect cells and reproduce. I take that to mean that they are examining the virus that's produced by the subject, which would be irrespective of any symptoms.
As far as shaking hands with someone that is asymptomatic, the protocols in our "new normal" calls for limiting that kind of behavior anyway. I haven't shook hands with anyone for months.
