In 2013, an Ebola outbreak began in Guinea. The country had no formal response system and the outbreak became the largest Ebola epidemic in recorded history. Guinea then completely overhauled their response system, and were able to successfully combat another outbreak in 2021. So what does an effective epidemic response look like? George Zaidan explores how different communities have taken action. This TED-Ed lesson was directed by Gavin Edwards, Movult, narrated by Jack Cutmore-Scott, music by Cem Misirlioglu.
