On the Fact that 66% of New York's Most Recent Corona-Virus Patients Are People Who Were at Home, Sheltering In-Place - https://www.forbes.com/sites/lisettevoytko/2020/05/06/majority-of-new-coronavirus-cases-in-new-york-are-from-people-staying-at-home-not-traveling-or-working/#399631621655

So the lockdown isn't even working, and the reason for it is that folks are still grocery shopping, going to gas stations, talking with their neighbors and family, going to the mailbox, handling plastics bought at the store (germs can live on plastic for days), etc., etc........and so unless you want to hermetically seal every person's house and have people in hazmat-suits delivering their food and medicine every day, a more common-sense approach is probably the answer (i.e., focusing on the elderly and sick, educating the general public, etc.).
