Main Reasons for Worm Infection (Reasons)
Poor personal hygiene: Not washing hands with soap after defecation is the main reason for the spread of worms. Worm eggs stick to the hands and under the nails and reach the stomach through food.
Contaminated food & water: Worm eggs can be found in unwashed fruits, vegetables, and unboiled water.
Not wearing shoes: Some types of worms (for example, tapeworms) enter the body through the skin of the feet when playing in the dirt or walking without shoes.
Unsanitary environments: Unsanitary toilets in public places and the habit of eating food without washing hands can cause the disease to spread.
Undercooked food: Eating undercooked meat (especially pork) can cause some types of worm infections.
