As the world grows more interconnected, epidemic disease outbreaks pose greater threats. Setting up public health regimes quickly wherever a new outbreak occurs is a vital worldchanging skill. This piece about the Marburg outbreak in Angola -- "Stalking a deadly virus, battling a town's fears" -- shows better than anything else I've read what it's like on the front lines:
UĂ?GE, Angola - For nearly four weeks, teams of health experts have been trying to set up a rescue operation in this town of windowless, crumbling buildings with no running water, intermittent electricity, poor sanitation and a perennially jammed telephone network. They are trying to contain the worst outbreak of one of the world's most frightening viruses, known as Marburg.
...For the people of UĂge, rampant death is now joined by the near equivalent of a space invasion: health workers encased in masks, goggles, zip-up jump suits, rubberized aprons and rubber boots as they collect corpses in the stifling heat. The garb is all white, a symbol of witchcraft here.
