   Vector-borne diseases — Fact sheet

   Statistiek

   Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700,000 deaths annually; malaria causes more than 608,000 deaths per year and dengue an estimated 40,000.

   “"Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700 000 deaths annually. … It causes an estimated 249 million cases globally, and results in more than 608 000 deaths every year. … More than 3.9 billion people in over 132 countries are at risk of contracting dengue, with an estimated 96 million symptomatic cases and an estimated 40 000 deaths every year." ”

   Berekening

   WHO’s >700,000/year vector-borne total is the aggregate anchor for this entry. Mosquito-borne diseases (malaria + dengue + Japanese encephalitis + yellow fever + West Nile + chikungunya + Zika) dominate that total, with malaria alone at ~608,000/year. Dividing 700,000 by a global population of 8 billion gives an annual per-capita hazard of ~8.75 × 10⁻⁵; compounded over 60 adult years yields ~5.25 × 10⁻³, or about 1 in 190.

   Onafhankelijkheid

   WHO vector-borne fact sheet aggregates WHO programmatic estimates across malaria, dengue, and the smaller arboviruses. Shares upstream with the WHO malaria fact sheet and the World Malaria Report below — treat the three WHO sources as a single institutional estimate rather than independent counts; the CDC US surveillance figure below is the independent cross-check.

   Malaria — Fact sheet

   Statistiek

   610,000 estimated malaria deaths in 2024; ~95% of all malaria cases and deaths occurred in the WHO African Region.

   Fragment

   “"The estimated number of malaria deaths stood at 610 000 in 2024 compared to 598 000 in 2023. … In 2024 the Region was home to about 95% of all malaria cases and deaths." ”

   Berekening

   WHO’s latest malaria estimate (610,000 deaths in 2024) is the single largest component of the vector-borne aggregate and justifies the concentration of risk in sub-Saharan Africa: 95% of malaria deaths occur in the WHO African Region, which is what drives the regional_breakdown figures below. The US traveler figure comes from the CDC malaria surveillance data (see corroborating note in body text) which reports roughly 2,000 US cases and ~7 deaths per year, almost entirely in returning travelers.

   Onafhankelijkheid

   WHO malaria fact sheet and WHO vector-borne fact sheet share an upstream (WHO programmatic estimates), so these two are not fully independent on the malaria number; they are used here for different roles — the vector-borne sheet for the aggregate, the malaria sheet for regional concentration and the most recent year.

   Statistiek

   ~2,000 US malaria cases reported per year; average of nearly 7 deaths per year over 2007–2022; 95% of US cases are in people who did not take appropriate prevention medication.

   Fragment

   “"Approximately 2,000 malaria cases a year are reported in the United States, and on average there were nearly 7 deaths per year for the period 2007–2022. … Most cases are in people who contract malaria while traveling to another country where malaria spreads and return to the U.S. 95% of people with malaria did not take appropriate malaria prevention medication." ”

   Berekening

   CDC US surveillance gives the non-endemic anchor: ~7 malaria deaths per year in a country of ~335 million, almost entirely in returning travelers. That is ~2 × 10⁻⁸ per person per year, i.e. roughly 1 in a million over 60 adult years. This is the basis for the "United States / Europe / Australia" row of regional_breakdown and for the 0.1× personal-factor multiplier for non-endemic travelers on prophylaxis. Methodologically independent of WHO.

   Onafhankelijkheid

   CDC surveillance (ICD-coded US death certificates + NMSS case reports) is drawn from a completely different pipeline than WHO’s programmatic malaria estimates, so this is meaningfully independent corroboration of the near-zero risk for non-endemic residents.

   Berekening

   Mosquito-specific mortality anchor: 597,000 malaria deaths alone account for the vast majority of the entry's 700,000 vector-borne disease deaths. Confirms that mosquito-borne diseases (malaria + dengue + others) dominate the vector-borne category.

   Onafhankelijkheid

   WHO World Malaria Report uses country-reported data and WHO modelling — the same upstream as the WHO vector-borne fact sheet but with malaria-specific detail.

   Berekening

   Used only as the shark-attack anchor for the body-text comparison "a mosquito kills roughly 90,000 humans for every one killed by a shark": 700,000 (WHO vector-borne annual deaths) / 8 (ISAF five-year average unprovoked fatalities/year) ≈ 87,500, rounded to "roughly 90,000". Not used anywhere in the native/normalized calculation for this entry, which is WHO-anchored throughout.

   Onafhankelijkheid

   Fully independent of the WHO/CDC pipeline above — ISAF is a standalone shark-attack database maintained by the Florida Museum of Natural History and shares no upstream with the vector-borne disease sources.
