Answer 1

Correct Answer - Option 3 : Plague

Concept-

• People who drink contaminated water or eat food washed in contaminated water can develop typhoid fever.
• Non-disposal of solid waste creates a contaminated atmosphere which can be a catalyst for Rodent related plague.
• A plague is an infectious disease that affects animals and humans.
• It is caused by the bacterium Yersinia pestis. This bacterium is found in rodents and their fleas and occurs in many areas of the world.
• Different ways typhoid fever can be contracted include:
• Using a toilet contaminated with bacteria and touching your mouth before washing your hands
• Eating raw vegetables that have been fertilised with human waste contaminated milk products
• Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.
