The authors were interested in the initial evolution of case incidence in the greater New York metropolitan area during March. They examined data from a private laboratory that tested 46,793 people for SARS-CoV-2. 57.1% of these people tested positive, with males of every race being disproportionally more affected than females >age 25, with a progressive male predominance as age increased. Of the positive people, 7292 were hospitalised upon presentation, with a further 882 people testing positive in an ambulatory setting prior to subsequent hospitalisation, a median of 4.8 days later. The total hospitalisation rate was therefore 8174 people (30.6% of positive people). There was a broad range (greater than 10-fold) in the cumulative number of positive cases across individual zip codes following documented first case incidents. The test positivity was greater for people living in zip codes with lower annual household income. Therefore SARS-CoV-2 incidence emerged rapidly and almost simultaneously across a broad demographic population in the region.
