The company decided to make Juneteenth a company holiday. They did this on Monday, announced it on Tuesday. Celebrated (or recognized) on Friday, today.
Spurned by a click-bait article I saw in my news feed, I searched for "covid-19 asymptomatic transmission rare" and found references to a WHO conference where this seems to have been said.
A few links in, I found the WHO Periscope video from which this information has been shared.
