Parasitic worm infections are caused by ingesting contaminated food or water, poor sanitation, and contact with infected soil or feces. These infections are common in areas lacking clean water and proper hygiene. Common worms include roundworms, tapeworms, and hookworms. People may get infected through undercooked meat or walking barefoot on contaminated ground. Symptoms vary but often include abdominal pain, fatigue, and weight loss. Treatment typically involves antiparasitic medications. Nizonide 500 mg is one such effective treatment, especially for intestinal parasites. Many nizonide 500 mg distributors provide global access to this medication, making it easier to manage and prevent reinfection.
