That's Right !!

  3. 10,000
  4. 100,000

C - On average, about 10,000 people per year die from Cholera. Cholera is a gastrointestinal disease that is caused by the bacterium Vibrio cholerae. The bacteria produces a toxin that results in severe diarrhea and vomiting. In 1999 there were 254,310 cases of Cholera world wide and 9175 deaths (a 13% decrease from 1998). In that same year, the United States there were only 6 cases and 0 deaths. This is because we use disinfectants, like chlorine, to treat the water we drink.
