Correct group of diseases caused by water contamination are:
Cholera, Dysentery, Polio, Typhoid
Understanding Diseases Caused by Water Contamination
Water contamination occurs when harmful substances, such as bacteria, viruses, parasites, or chemicals, get into water sources. Drinking or coming into contact with this contaminated water can lead to various illnesses.
Let's examine the options provided to identify the correct group of diseases caused by water contamination.
- Option 1: Cholera, Dysentery, Polio, Typhoid
- Cholera: A severe diarrheal disease caused by the bacterium Vibrio cholerae, often spread through contaminated water.
- Dysentery: An intestinal infection causing diarrhea with blood or mucus. It can be caused by bacteria (like Shigella) or amoebas, often spread through contaminated water or food.
- Polio: A viral disease (Poliovirus) that can cause paralysis. The virus is transmitted through the fecal-oral route, often via contaminated water.
- Typhoid: A bacterial infection (Salmonella Typhi) spread through contaminated food or water.
All the diseases listed in this option are well-known to be transmitted through contaminated water.
- Option 2: Cholera, Jaundice, Typhoid, Anaemia
- Cholera and Typhoid are waterborne.
- Jaundice is a symptom of various conditions, including Hepatitis A, which can be waterborne.
- Anaemia is a condition characterized by a deficiency of red blood cells or hemoglobin, often due to iron deficiency or other nutritional issues, not typically caused by water contamination.
- Option 3: Anaemia, Scurvy, Emphysema, Typhoid
- Typhoid is waterborne.
- Anaemia is not typically waterborne.
- Scurvy is caused by Vitamin C deficiency, not water contamination.
- Emphysema is a lung condition, often linked to smoking or pollution, not water contamination.
- Option 4: Cholera, Jaundice, Typhoid, Scurvy
- Cholera, Jaundice (as a symptom of waterborne Hepatitis A), and Typhoid can be waterborne.
- Scurvy is caused by Vitamin C deficiency, not water contamination.
Based on the analysis, the group that consists entirely of diseases commonly caused by water contamination is Cholera, Dysentery, Polio, and Typhoid.
