Cholera is an example of a pandemic disease that
A) has multiple wild animal reservoirs and is thus difficult to eradicate.
B) spreads from a common source and could be controlled with adequate clean water and waste sanitation measures.
C) is spread through direct contact and has only a human reservoir.

Accepted Answer

Cholera is a waterborne disease that spreads from a common source contaminated with the bacterium Vibrio cholerae. The disease can be controlled with adequate clean water and waste sanitation measures. While there are multiple reservoirs for the bacteria in the environment, including water and various aquatic animals, the disease is primarily transmitted between humans through contaminated water or food. Cholera has been known to cause pandemics throughout history, and continues to be a major public health concern in areas where sanitation infrastructure is lacking.
