28 Feb 2020, first case reported in the UK.
16 March 2020, first advisories to shield/shelter in place issued
So, yes, it's been five-ish weeks now.
Five very long weeks of being fed conflicting information, disinformation, misinformation, and guesses.
We still have no real clue how many people are infected, since the only testing going on is at the hospitals in the UK and that's the only way to know who is infected. We are not even sure of the actual death rate.
https://edition.cnn.com/2020/04/07/uk/coronavirus-uk-deaths-intl-gbr/index.html In the USA they have no idea, either. I heard one interview with a scientist who was saying it was not out of line to multiply any numbers of infected persons published by a factor of 100 to account for the silent cases. Deaths from Covid are only reported if there have been tests proving infection, in the USA. Coroners cannot easily get test kits, so those deaths are not considered in the stats. So heaven only knows how many people this has killed already.
Thankfully they ~do~ have an antibody test, and are just waiting for FDA approval to mass produce it. That would let people know, at least, if they've already had it. Won't do much for anyone who has not, other than confirming that status. Where the world goes from there, who knows?
Given that, the sanest thing to do is walk at sunrise and listen to the birds.
