Explanation:
Improvement in water and sanitation can control many diseases. This is a totally true statement. When an area or place is clean, the people living there are healthy and free from diseases. For example, mosquitoes like to breed in unclean areas without sanitation. If the area was cleaner, no mosquitoes would breed there. Unclean surroundings give rise to the breeding of many insects like mosquitoes and flies. They are both considered the enemies of humans and can spread malaria and dengue. If we improve these conditions, many diseases would be stopped. These days, many people are getting dengue. To stop this, we need clean surroundings. Rats also spread diseases. This is because they walk in sewages and come to our home's water pipes, making the water unclean. Flies are another spreader of diseases. They sit on many unclean places like toilets, garbage, etc. when they sit on our food, they spread the germs, making us sick. Animals and insects are not only the problem. Soil and water pollution is also a problem. when marine creatures like fish eat garbage, they fall sick and die. When humans eat those affected marine creatures, they fall sick from the garbage the fish had eaten. the same applies for cows too. So, if we clean our sewages, purify our water and sanitise our surrounding, many diseases can be stopped.
Answer:
For example; diarrhoea, jaundice, cholera, etc. happen because of contaminated food and water. Similarly, dengue and malaria happen because of living in unhygienic conditions. These diseases can be easily prevented by improvement in water and sanitation.
