Helminth infections are caused by parasitic worms, which can live in the human body and lead to various health issues. These worms, such as tapeworms, roundworms, and flukes, often enter the body through contaminated food, water, or soil. Once inside, they can cause symptoms like abdominal pain, diarrhea, and fatigue, affecting a person's overall well-being. Preventing helminth infections involves good hygiene practices, such as washing hands regularly and cooking food thoroughly. In areas where these infections are common, public health measures, like improving sanitation and providing clean drinking water, are essential. Treatment usually includes medications that target the specific type of worm causing the infection.
