Main reasons for worm infestation
Unclean food: Worm eggs can enter the body by eating unwashed vegetables, fruits, and undercooked meat.

Lack of hygiene: Eating food without washing hands with soap is a major cause of worm infestation. Dirt accumulates between the nails, which allows worm eggs to enter the body.

 

Contaminated water: Worm eggs can enter the body by drinking untreated water.

Open defecation: Worm eggs can be found in the soil. Some types of worms can enter the body through the feet by walking without shoes.

Unhygienic conditions: Not keeping the environment clean and not washing hands thoroughly cause worm infestation.
