Cholera is a bacterial infection which infects intestines. The bacterium stays in the small intestine and secretes a toxin. Abdominal pain and diarrhea are the symptoms of cholera. This condition is mainly caused by consuming unhygienic food or drinking contaminated water. Watery diarrhea makes a person dehydrated. Hence to prevent dehydration, one must take fluids at regular intervals.

Dengue fever:

Dengue fever is another infectious disease caused by mosquito bites. It is a viral infection. Aedes aegypti mosquito acts as virus carrier and when it bites, the virus is transmitted into a person. High fever and red rash on several areas of skin are the symptoms of dengue fever.
