🦟 Human deaths from malaria, dengue, yellow fever, West Nile virus & Chagas disease (1700 – 2025 | annual global estimates)
📊 Synthesized from IHME/GBD 2021, WHO, CDC, and peer‑reviewed historical reconstructions (The Lancet, PLoS NTDs).
Y‑axis is logarithmic to display wide ranges (from ~10 to >2 million deaths/year).
🧪 Data before 1950 are estimates based on epidemic records and demographic modeling; shaded areas indicate higher uncertainty.
⚠️ Data transparency: No single source provides 300 years of continuous global data for all five diseases.
This chart merges (1) IHME Global Burden of Disease (1990–2021) annual death estimates,
(2) historical benchmarks from WHO bulletins, CDC archives, and peer‑reviewed studies (see sources below),
(3) linear interpolation for years with no direct estimates, and (4) known epidemic peaks (e.g., yellow fever in 1793, 1878).
All values are annotated on hover. West Nile virus only entered the Western Hemisphere in 1999 – earlier years are zero/negligible.
