The report also found that during the weeks of March 8 and March 15, there was an increase in confirmed cases of COVID-19 among New Yorkers under 18 years of age. The DOHMH estimated there was an increase in prevalence and undetected cases of COVID-19 among youths, which begs the question what role children played in community transmission at the beginning of the pandemic, and how effective school closure is as a mitigation strategy. It comes down to the limited testing availability, which is still a problem for most states more than four months after the first case of COVID-19 was reported. Gov. Andrew Cuomo on Thursday called the report "damning" and said that the China and Europe travel ban was the federal government's first mistake in the country's failed attempt to slow down the spread.
