How New York City botched COVID-19 response: Report
New York City botched its COVID-19 response, according to an investigation conducted by Scott Stringer, the city's comptroller, who released findings from his inquiry Wednesday.
According to Stringer, key emergency response agencies, including the health department and the NYPD, were intentionally excluded from communications and decision-making "when time was of the essence."
The comptroller also described persistent confusion about the chain of command between agencies and a significantly delayed response to the pandemic.
Officials waited until late February to even begin planning for a worst-case scenario, despite knowing about the impending crisis in January. Stringer called on the mayor, as well as the future mayor, to conduct a thorough review of the city's emergency planning process.
"We cannot erase the mistakes of the past," he said. "But we can make sure we are prepared for future emergencies."
