It may sound like the plot of a movie: police find a young man dead with stab wounds. Tests quickly show he'd had Ebola.
Officials realize the suspects in the case, men in a local gang, may have picked up and spread Ebola across the slum. These men are reluctant to quarantine themselves and some – including a man nicknamed "Time Bomb" – cannot even be found.
This scenario actually unfolded in the West African nation of Liberia in 2015. And what followed was a truly unconventional effort by epidemiologists to stop a new Ebola outbreak.
This team of public health officials had to go to extraordinary lengths to keep the disease from spreading further — from halting a police investigation, to suggesting officials allow illicit drugs into a medical facility, to tracking down the elusive "Time Bomb."
It was all done in an effort to overcome what can be the biggest obstacle in public health: a severe lack of trust.
