• Answer:

  Cholera is caused by bacteria in contaminated water. My guess is that it is more difficult to provide clean water at sea level due to physics, there is no natural gravity to pull sewage away. That is why Cholera is more common in areas that are both at sea level and have not yet developed the infrastructure to dispose of waste.
