about half the world — and rising with the climate
NTDs are a leading cause of preventable blindness and disability. They are concentrated in sub-Saharan Africa, South Asia and Latin America, and disproportionately affect children and the rural poor. Many are controlled through inexpensive mass drug administration — among the best value-for-money interventions in global health.
▦ The biggest by people affected modeled
People infected or requiring preventive treatment (WHO estimates; "infected/affected", distinct from "at risk"):
Estimates mix prevalence and treatment-need depending on the disease and carry wide uncertainty; dengue is shown by population at risk in the headline above, not here, because it is a different measure. Several diseases overlap geographically, so totals are not additive.
▤ Selected NTDs — dated status & toll modeled interpretive
Status is an interpretive summary of WHO programme classifications: eradicating (near zero) · eliminating (as a public-health problem in many countries) · controlling (mass treatment) · high-fatality · rising. Tolls are approximate dated WHO figures. This illustrative selection is not the complete current WHO list.
◆ Progress & the 2030 roadmap interpretive
WHO's NTD Road Map 2021–2030 targets a 90% reduction in people needing interventions, 100 countries eliminating at least one NTD, and the eradication of two (dracunculiasis and yaws). Progress is real but uneven and was set back by COVID-19 disruptions to mass-treatment campaigns. Interpretive synthesis of WHO reporting.
◍ Why "neglected" interpretive
Interpretive synthesis. The paradox of NTDs: they affect more than a billion people yet attract a tiny fraction of health research funding, because those affected are poor and the diseases are largely absent from wealthy countries — even though many can be controlled or eliminated very cheaply.
