Taking aim at cholera

In 1854, John Snow's work on cholera in London immortalised the power of mapping as a tool for disease prevention and control. Over 160 years later, a more ambitious effort to map cholera has been reported in The Lancet. Forgoing so-called shoe leather epidemiology in favour of big data, Justin Lessler and colleagues2 used 279 cholera datasets covering 2283 locations in 37 countries, and cluster-level maps of access to improved water and sanitation in 41 countries, to map cholera incidence across sub-Saharan Africa at a 20 km × 20 km grid scale.

An interesting article from The Lancet by Eric Mintz.

"Sustainable water supply, sanitation, and hygiene (WaSH) infrastructure is crucial for ending transmission of cholera and other diseases transmitted by the faecal–oral route, and is a Sustainable Development Goal 2030 target in its own right, but its construction is costly and time consuming. Oral cholera vaccines, which are effective at reducing cholera transmission in the short term (3–5 years), remain in short supply relative to global demand despite substantial success in increasing their production and accessibility."
