Answer 1

Typhoid is a disease that is caused by Salmonella typhi. It is a common summer disease. It is a water-borne disease that is spread by the bacteria entering the human body through the contaminated oral-fecal route. It can be prevented by taking precautions like - 

1. Avoid excess storage of water to prevent any kind of contamination and breeding of mosquitoes and harmful micro-organisms.

2. Wash hands well before eating.

3. Cook the food well, eat hot food, and keep them closed always. Avoid eating raw food.

4. Drink only boiled water or treated water.

5. Maintain cleanliness and good sanitary conditions.

Once the Salmonella typhi enters the human body through the oral-fecal route, it causes symptoms like nausea, vomiting, weakness, fatigue, loss of appetite, abdominal pain, and high fever. 

Water pollution can be prevented by - 

1. Preventing disposal of garbage in water and water bodies.

2. Preventing the mixture of excreta and waste materials with groundwater and other water sources.

3. Minimum use of chemicals, fertilizers, pesticides, etc. and take measures to prevent its seepage into the groundwater.

4. Using eco-friendly detergents, soaps, etc which get washed down into the drainage.
