GP's here are telling people they are basically no longer infectious 7 days after first developing symptoms and testing positive, not sure how that has come about but it seems to be widely applied. The idea is that 7 days after symptoms appear you are already past shedding live virus.
The researchers seem to think people are most likely highly infectious just before symptoms appear, that sort of makes sense because symptoms are actually a sign that someone's body has detected the virus and begun defending itself. This also explains how Sars-CoV-2 is so readily and widely transmitted, you've spread it well before you get sick.
Tough gig being a medical professional and virologist, you almost have to predict the future.
