I've seen mixed messages as to the infectiousness of the virus with regards to asymptomatic carriers (or those with hardly-noticeable symptoms). Can anyone point me to some recent research that clarifies this? It seems like the most important statistic for creating policy in the near future, as fevers can be detected with thermal cameras.

- eiji 6y agoCan somebody explain what is meant by viral shedding here? Some of those links mention cotton swabs used for testing. So viral load is shedding of infectious "compound" into throat and nose mucus. But no symthoms means there is no cough yet. How much of that is shedding into air you breath out? Is it assumed this is the same?
- tomrod 6y agoIt means you're infectious, and measurably so.
- Fjolsvith 6y agoBut not for life. The infection ends. And, lately, with the likelyhood of death being greatly, greatly reduced.
- tomrod 6y agoI anticipate that it would be common knowledge that viral shedding is known to end (i.e. people get better or die). Outside a negligible amount of cases, is this not common knowledge?
