Where is the best place to get data on disease epidemiology?

There is no single best source. Modelled burden (deaths, DALYs, incidence estimates) comes from IHME's Global Burden of Disease; reported surveillance counts come from the agency that collects them (CDC NNDSS for the US, ECDC's Atlas for the EU/EEA) or from ENCLAI, which harmonises national bulletins across countries; event narratives come from WHO Disease Outbreak News and ProMED. Pick by the question, as in the matrix above.

Is WHO Global Health Observatory data free to reuse?

Free to read. WHO's data policy and terms of use allow non-commercial, not-for-profit use with acknowledgement; commercial use needs WHO's permission. WHO does not publish its GHO data under CC BY 4.0 (sources 8–10).

What is the difference between GBD estimates and reported case counts?

GBD figures are model outputs with uncertainty intervals, revised between rounds; reported counts are what health authorities actually notified, incomplete where surveillance is weak. The two should not be spliced into one series.

Which source has weekly infectious-disease counts?

CDC's weekly provisional tables on data.cdc.gov for the United States; ECDC's weekly datasets for influenza, West Nile virus, diphtheria and Zika in the EU/EEA; ENCLAI for weekly and monthly national bulletins across 230 countries and territories, with the reporting authority named on each page.

Where to get disease epidemiology data

WHO, GBD, ECDC, CDC, ProMED, HealthMap, GIDEON, Our World in Data, BlueDot/Airfinity and ENCLAI — which source answers which question, what it costs, how fresh it is, and where each one, including ours, loses. Competitor facts were read on each organisation’s own site on 7 November 2026; every such cell carries a numbered source, and anything we could not confirm is marked rather than asserted.

Read this first. We wrote this page, and we publish one of the sources on it. That is a conflict of interest and you should read the table accordingly. What we can offer instead of a promise is a way to check: every competitor cell is footnoted to the page it was read from, with the date and a confidence word; the section Where ENCLAI loses is not padding; and if one of the free public sources answers your question, use it.

Three kinds of thing get called "epidemiology data" and mixing them is the commonest mistake: modelled estimates (IHME GBD, WHO estimates), reported surveillance counts (national notifiable-disease systems, ECDC TESSy, CDC NNDSS), and event reports (WHO DON, ProMED). Pick by the question. This table says which source answers which question, what it costs, how fresh it is, and where ENCLAI fits — including where it does not.

The score is a plain count of the cells above and nothing more. Two cautions: we chose the 20 parameters, and a cell we could not confirm on an organisation’s own pages scores zero, which penalises the vendors that publish least (BlueDot / Airfinity, GIDEON).

Where ENCLAI loses

Burden and mortality estimates: we do not model. Use GBD or WHO.
US sub-state detail: NNDSS weekly provisional tables (data.cdc.gov) and the WONDER annual summary query go deeper than we republish. ¹⁷¹⁸
EU age/sex breakdowns: ECDC Atlas has them; we carry totals. (Age/sex breakdown availability not re-verified this session; ECDC's page says only "a variety of tables and maps" ¹³.)
Earliest rumours: ProMED and HealthMap see media/clinician reports before a bulletin exists; our signals layer is deliberately slower and separate from the confirmed record.
Provenance depth: 46 international bodies are named in full; national feed identifiers are not published on public pages (paid tier) — a reviewer who needs every source URL will prefer the primary portal.
History before 2015: sparse; GIDEON's archive is deeper (vendor claims data "going back as far as 1348 AD") ²⁶²⁸.
