The Pneumatic Plague in Seychelles

Imagine that you have pneumatic plague. Over the course of 24 hours, how many people do you come in contact with? In 2017, when we are so mobile, right? Like this man, this index case, he shared a taxi with multiple people. It takes a ton of real detective work to find all of these people and make sure that you're following up in order to put a ring around the outbreak and try and contain it.
