Isolate vulnerable: elderly, sick. Let virus spread to everyone else, creating heard immunity, just like flu. Then the virus dies out, no threat to elderly after 4 weeks or so. No second wave and prolonged maniacal lockdown which wasn't even required to begin with. Isolation only drags it out longer and longer, increasing social and psychological strife and eventual health issues and loss of life through economic hardships, resulting in more deaths.

Those who have serious condition can be treated and healed within 2 days, like a doctor has been doing in NY with no loss of life, using chloroquine and zinc. Thats what should be done.
