Worldwide, the novel coronavirus is officially a pandemic. Within the US, 44 states and Washington, DC, have identified people infected with the virus. The global wave of Covid-19 is about to crash over the country—and the weak point in what happens next is the nation’s health care workers. Or rather, the health of the nation’s health care workers.

The collision of two problems—the slow roll-out of tests for the virus and low supplies of face masks and other protective gear—have left hospital officials unable to say for sure how many nurses, physicians, and other employees might already have been exposed via contact with patients. That has led to hundreds of health care workers being sent home for just-in-case quarantines, and to stress on the medical systems in the states that first experienced community transmission, including Washington, California, Massachusetts, and New York.
