“Income is one of the stronger predictors of health outcomes — and of how long we live,’’ Woolf said. “Lost wages and job layoffs are leaving many workers without health insurance and forcing many families to forego health care and medications to pay for food, housing, and other basic needs. People of color and the poor, who have suffered for generations with higher death rates, will be hurt the most and probably helped the least. They are the housekeepers in the closed hotels and the families without options when public transit closes. Low-income workers who manage to save the money for groceries and reach the store may find empty shelves, left behind by panic shoppers with the resources for hoarding.’’

Is there another way?

One of the best ideas I have come across 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.

For all these reasons, he argued, we need to pivot from the “horizontal interdiction” strategy we’re now deploying — restricting the movement and commerce of the entire population, without consideration of varying risks for severe infection — to a more “surgical’’ or “vertical interdiction’’ strategy.

A surgical-vertical approach would focus on protecting and sequestering those among us most likely to be killed or suffer long-term damage by exposure to coronavirus infection — that is, the elderly, people with chronic diseases and the immunologically compromised — while basically treating the rest of society the way we have always dealt with familiar threats like the flu. That means we would tell them to be respectful of others when coughing or sneezing, wash their hands regularly and if they feel sick to stay home and get over it — or to seek medical attention if they are not recuperating as expected.

Because, as with the flu, the vast majority will get over it in days, a small number will require hospitalization and a very small percentage of the most vulnerable will, tragically, die. (That said, coronavirus is more dangerous than the typical flu we are familiar with.) As Katz argued, governors and mayors, by choosing the horizontal approach of basically sending everyone home for an unspecified period, might have actually increased the dangers of infection for those most vulnerable.

“As we lay off workers, and colleges close their dorms and send all their students home,’’ Katz noted, “young people of indeterminate infectious status are being sent home to huddle with their families nationwide. And because we lack widespread testing, they may be carrying the virus and transmitting it to their 50-something parents, and 70- or 80-something grandparents.’’
