Really interesting article! It's impressive how quickly we are finding out different things about the transmission of the virus because so many resources are going towards combatting this outbreak.

It may or may not be of interest to you, but I thought it was worth bringing to your attention since I haven't heard of any other countries experimenting in such a way.
