[Dire] PPE shortages. Limited COVID tests. Sparse tracking of viral spread. Layers of flawed policies handed down by health care executives and politicians, and lax enforcement by government regulators.

This number is far higher than that reported by the U.S. government, which does not have a comprehensive national count of health care workers who’ve died of COVID-19.
