How door-to-door canvassing slowed an epidemic

Liberia was the epicenter of a high-profile Ebola outbreak in 2014-15, which led to more than 10,000 deaths in West Africa. But for all the devastation the illness caused, it could have been worse without an innovative, volunteer-based outreach program Liberia’s government deployed in late 2014. A study shows how much that program, consisting of door-to-door canvassing by community volunteers, spread valuable information and changed public practices during the epidemic.
