Question

The disease caused by polluted water is
A. Typhoid
B. Cholera
C. AIDs
D. Dengue

Answer 1

Water pollution is defined as an addition of foreign substances ( organic, biological, or radiological) to water, or a change in its physical property (temperature) that constitutes a health hazard or otherwise makes it less fit or unfit for use.

Complete answer:
1. Typhoid: The disease spreads by food and water contaminated with faeces of the patient. House flies may carry the pathogens from the faeces to the food, milk, and water. The causative organism enters via the mouth, reaches the intestine, and causes lesions in the intestinal wall. Typhoid is a common bacterial disease caused by a rod-like bacterium, Salmonella typhi.
2. Cholera: Cholera is a serious intestinal tract infection caused by bacteria called Vibrio cholerae.An individual gets cholera by washing or consuming contaminated water or eating food washed or irrigated with contaminated water. The symptoms of cholera include vomiting, headache, and abdominal cramps. In highly polluted areas, one infected person can contaminate the water with the disease-causing bacteria and affect the whole population.
So, the correct answer is option A. Typhoid and B. Cholera

Additional Information:
1. AIDs: Acquired Immunodeficiency Syndrome is caused by the Human Immunodeficiency Virus HIV. AIDs is transmitted only by contact of infected cells containing the blood of a patient with the blood of a healthy person.
2. Dengue: Dengue fever is a disease caused by a family of viruses transmitted by Aedes mosquitoes. Symptoms of dengue fever include severe joint and muscle pain, swollen lymph nodes, headache, fever, exhaustion, and rash.

So, the correct answer is “Option A Typhoid and B Cholera”.

Note: Both cholera and typhoid are caused by contaminated water or polluted water. Hepatitis is a viral disease caused by contaminated water and infects the liver.
Jaundice, loss of appetite, fatigue, discomfort, and high fever are symptoms of hepatitis.
