2s Disease Surveillance — CDC NNDSS Weekly Data is a paid API for AI agents from 2s.io, paid per call via x402, $0.0012/call, status unknown (last checked 2026-10-12).

Returns CDC NNDSS weekly disease surveillance counts (current week, cumulative YTD, prior-year comparisons) filterable by disease/condition, US location, and MMWR year.

How this service works

Current US notifiable-disease surveillance from the CDC NNDSS (National Notifiable Diseases Surveillance System) weekly tables. Returns provisional weekly case counts for ~139 nationally notifiable conditions (e.g. Measles, Pertussis, Mumps, Hepatitis A, Lyme disease, Gonorrhea, West Nile, Dengue) by reporting area and MMWR week, updated weekly. Filter by condition (substring, case-insensitive: "measles" matches "Measles, Indigenous"), location (a reporting area: a US state full name like "California", "New York City", "U.S. Residents", a census region like "Pacific", or a territory), year (MMWR year, 2022 to current), and weeks (most-recent N observations). At least one of condition or location is required. Each record reports the current-week count, the previous-52-week maximum, cumulative cases YTD this MMWR year, and cumulative YTD the prior year for same-week comparison. Public-domain CDC federal data via data.cdc.gov. Use this to see live disease activity and outbreaks that postdate an agent's training cutoff.

Output

A JSON object with an `items` array of weekly surveillance records, each containing the MMWR week and year, reporting location, disease/condition name, current-week case count (with flag if preliminary), cumulative YTD count, prior-year YTD count, and prior 52-week maximum. Also includes total record count, applied filter metadata, and CDC source/license information.
