Data sources

→
CDC National Wastewater Surveillance System (NWSS) — Wastewater viral activity levels for COVID-19, Influenza A, RSV. Updated weekly.
→
NYSDOH Communicable Disease Annual Reports — County-level case counts for 61+ diseases. Updated annually (published ~February).

Notes

  • NYC borough data (Bronx, Brooklyn, Manhattan, Queens, Staten Island) is reported as a combined NYC total in the annual case data and is not broken down by borough in the NYSDOH source.
  • Case counts below 5 are suppressed by NYSDOH for privacy — these appear as null in disease_cases_annual.csv with is_suppressed = 1.
  • Wastewater data coverage varies by county. Not all NYS counties have active monitoring sites.
  • All source data is produced by US government agencies and is in the public domain. Our processing code is MIT licensed.
