Officials in California and Seattle – the sites of the earliest cases of the epidemic in the United States – said they only included deaths from Covid-19 when the disease was confirmed by tests.
New figures in New York cover the weeks between March 11 and April 13, starting from a time when the virus had already spread in the city and its surrounding suburbs. De Blasio and Governor Andrew M. Cuomo closed large areas of the city and state by the third week of March.
New York City has been reporting additional cases to the Federal National Center for Health Statistics for more than a week, health officials said. But Dr. Barbot said the city would continue to only report confirmed cases to the Centers for Disease Control, as that was what had been requested. “We are more than happy to report on the likely ones,” she said.
The C.D.C., in its directives to local governments, recommended that cases of “suspected” coronavirus infection be recorded on death certificates since before New York recorded its first death on March 14.
Spokesperson for the C.D.C. said the total coronavirus deaths in New York on Monday were 6,182 – the same number publicly reported by the city’s health department on Monday, before the new figures are included. On Tuesday, the city’s count increased to 6,589.
The city and state have sometimes differed in their New York death toll. The state said on Monday that 7,349 people had died from the virus in the city. City officials have complained that they are at the mercy of the state, which has been slow to share the data it receives from hospitals and retirement homes. The state health department said on its website that the discrepancy is due to the fact that the city and the state use “different data systems.”
