This is also an excellent question because the amount of time that people shed the virus after they've been infected is so variable and it can be as long as over a month for some individuals. So some of that's all true but if you are immune compromised, your immune system is not working as well, by age and other factors that we will learn more about. But you know it's for reasons like that, that within the hospital and for health care workers we actually retest people to see if they're negative before we can clear them to either come back to work in the case of a health care worker or for patients be able to stop their isolation precautions. In the public I think that you know general rules have been formed by a public health that kind of capture the vast majority people that by 14 days most people will be less infectious to others so they would then be able to stop the quarantine or the self-isolation at that point.
