According to the source of all knowledge:
“[Cholera t]ransmission is primarily through consuming contaminated drinking water or food… Primary treatment is with oral rehydration solution and if these are not tolerated, intravenous fluids. Antibiotics are beneficial in those with severe disease.”
But according to some rural Haitians, cholera is transmitted primarily through witchcraft, and primary treatment is performed by killing practitioners of witchcraft. Violent witch hunts originating in the Grand Anse region of Haiti have resulted in the murder of at least 12 people so far. But on the other hand, cholera has killed nearly 1,900 so far, so the armed hordes have a bit of catching up to do in order to be quite as evil as the cholera itself. From the Atlanta Journal-Constitiution:
Machete-wielding mobs have since lynched and killed a dozen people accused of practicing such witchcraft, burning the bodies of their victims, national police spokesman Frantz Lerebours said.
The Haitian government is on the side of sanity here:
In response to the killings, the government in Port-au-Prince issued a statement Thursday imploring: “Cholera is a microbe … The only way to protect one’s self against cholera is to observe the principles of hygiene.”
“There is no cholera powder, nor cholera zombie, nor cholera spirit” and Vodou priests “can neither treat cholera, nor make a powder that gives cholera,” it said.
That should clear things up, right?
