What do you know about cholera?
What is Cholera?
Cholera is the illness caused by a
bacterium called Vibrio cholerae. It
infects people’s intestines (肠), causing
diarrhea (腹泻), vomiting and leg
cramps. The most common cause of
cholera is by someone eating food or
drinking water that has been infected
with the bacteria.
After a disaster, this is a very real
danger, since regular, clean water
and food supplies are often
unavailable. The disease can be
spread even further by infected people
using already dirtied water sources to
clean themselves or dispose of waste.
