Data & Statistics
Communicable Disease Surveillance Data

Data for diseases reported to the Bureau of Communicable Disease are available on EpiQuery: Communicable Disease Surveillance Data (CDSD). EpiQuery is an interactive, user-friendly system designed to guide users through basic data analyses.

The CDS data are derived from reports filed with the New York City Department of Health and Mental Hygiene (DOHMH) as required by Section 11.03 of the New York City Health Code. The Bureau of Communicable Disease manages the data derived from these reports. Data are cleaned, analyzed and reported for public health surveillance. Minor variations in data presented here and that presented elsewhere (including other publications of the NYC Department of Health and Mental Hygiene) may be due to several factors, including reporting delays, census data availability, corrections, and data-processing refinements (for example, the removal of duplicate reports).

The data presented in EpiQuery include all confirmed and probable cases of disease reported since 2000 in NYC residents. Reported cases, crude rates, and age-adjusted rates are available by select demographic (age group, sex) and geographic (borough, neighborhood) characteristics.

Starting in 2006, data can also be stratified by two additional characteristics. First, data can be stratified by area-based neighborhood poverty, according to the percentage of the population in the case’s zip code below the federal poverty level, per the American Community Survey 2007-2011: low poverty (<10% below the federal poverty level), medium poverty (10 to <20%), high poverty (20 to <30%), and very high poverty (≥30%). Secondly, data can be stratified by high-risk neighborhood status, i.e., whether the case resides in a zip code associated with one of the three District Public Health Offices (DPHO) in (1) South Bronx, (2) North and Central Brooklyn, and (3) East and Central Harlem; these are the neighborhoods in New York City with the highest rates of morbidity and mortality.

Rates for infant botulism and invasive Streptococcus (group B) were calculated per 1,000 live births using data from the NYC DOHMH Office of Vital Statistics; if live birth data were not yet available for a given year, then live births from the most recent available year were used. All other rates were calculated per 100,000 population using NYC DOHMH population estimates, modified from US Census Bureau interpolated intercensal estimates, updated June 2013.
