"The Fight Against COVID-19: “Bending the Curve” & Then What?"

Ours is not to reason why,
Ours is just to buy and buy.

From Wolf Street, April 4: 

Eradicate the virus — without a vaccine? Manage infection rates to let the population “build immunity through suffering” until a vaccine is available? How can we revive the economy without risking thousands of deaths in fresh outbreaks?

By Wisdom Seeker, a WOLF STREET Commenter with a physical sciences Ph.D., San Francisco Bay Area: 
I think we’re now at the turning point in the fight against COVID-19. Everyone’s now acting to stop the spread, and the early hot spots in Europe, North America, and Australia are seeing signs of progress, just as the Asian nations did earlier. There is a long road ahead, and we have to decide which route to take, but Western societies are showing they can handle this too. In this post I’m going to show updated versions of my three favorite graphs, which tell the story and lead to the single biggest public policy-making challenge many nations may face this decade.

Bending the Curve in California: Just-in-Time Deliverance?
The graph below shows confirmed cases in Los Angeles, the San Francisco Bay Area, and California as a whole, with South Korea and Italy as contrasting examples. The vertical axis is a log scale, so exponential growth shows up as a straight line. Data sourced from the Johns Hopkins database and the California state and individual county reports.

Los Angeles lost to the Bay Area on April 2 and became California’s new COVID-19 hot spot. Shelter in place has begun working for the Bay Area, but confirmed cases have still doubled in the past week. So on March 31, our local public health officials released what I call “Shelter-in-Place 2.0,” a tighter set of rules, to try to avoid the hospital-overload scenario which hit Wuhan, Milan, Madrid, and now New York. Face masks are also becoming trendy outside the home! Will the Bay Area get a “just-in-time deliverance”, or is the worst still yet to come?

Locally, Santa Clara County – the heart of Silicon Valley – reports 30% of ICU space in use by COVID patients, 38% used by other patients, and 32% available. So they can take a doubling in COVID ICU cases without overloading, and other Bay Area hospitals have headroom too....
