One of the best ideas I have come across (for combating the spread of Coronavirus) was offered by Dr. David L. Katz, the founding director of Yale University’s C.D.C.-funded Yale-Griffin Prevention Research Center and an expert in public health and preventive medicine. Katz wrote an Op-Ed in The Times on Friday that caught my eye. He argued that we have three goals right now: saving as many lives as we can, making sure that our medical system does not get overwhelmed — but also making sure that in the process of achieving the first two goals we don’t destroy our economy, and as a result of that, even more lives.
