Cumulative incidence and diagnosis of SARS-CoV-2 infection in New York	2020-06-17		.txt	text/plain	3431	178	44	SARS-CoV-2 cumulative incidence was estimated from antibody reactivity by first post-stratification weighting then adjusting by antibody test characteristics. CONCLUSIONS: From the largest US serosurvey to date, we estimated > 2 million adult New York residents were infected through late March, with substantial disparities, although cumulative incidence remained below herd immunity thresholds. Cumulative incidence among non-institutionalized adults, by geographic and demographic features, was estimated from weighted reactivity rates that were adjusted for validated test characteristics. We estimated SARS-Cov-2 cumulative incidence from observed antibody reactivity using two sequential steps: 1) post-stratification weighting to standardize to the New York State population and 2) adjustment by estimated antibody test characteristics. Test-characteristic adjusted cumulative incidence values were multiplied by the one-and two-way non-institutionalized adult populations (e.g. excluding settings such as prisons and nursing homes) from the American Community Survey 2014-2018 Public Use Microdata Sample file [23] .	./cache/cord-274761-c2hgkbg6.txt	./txt/cord-274761-c2hgkbg6.txt
