More studies... 'What the data say about asymptomatic COVID infections'
People without symptoms can pass on the virus, but estimating their contribution to outbreaks is challenging.

(we still don't fully understand this...and more research in progress)

(we still don't fully understand this...and more research in progress)
"...evidence suggests that about one in five infected people will experience no symptoms, and they will transmit the virus to significantly fewer people than someone with symptoms." https://www.nature.com/articles/d41586-020-03141-3
"Research early in the pandemic suggested that rate of asymptomatic infections could be as high as 81%. But a meta-analysis published last month, which included 13 studies involving 21,708 people, calculated rate of asymptomatic presentation to be 17%." https://www.nature.com/articles/d41586-020-03141-3
"The issue with putting a reliable figure on the rate of asymptomatic COVID-19 is distinguishing between people who are asymptomatic and pre-symptomatic..."
“Asymptomatic is someone who never developed symptoms ever throughout the course of their disease, and pre-symptomatic is somebody who has mild symptoms before they do go on to develop symptoms,” https://www.nature.com/articles/d41586-020-03141-3
