Worm infections can spread from person to person, depending on the type of parasite involved. Some, like pinworms, are highly contagious and spread through direct contact or contaminated surfaces. Others, such as tapeworms, require ingestion of contaminated food or water. Proper hygiene and sanitation are key to preventing transmission. The nitazoxanide 500mg is an effective antiparasitic medication used to treat various worm infections, including those caused by protozoa and helminths. It works by interfering with the parasite’s energy production, leading to its elimination. Consulting a healthcare provider for proper diagnosis and treatment with nitazoxanide 500mg is essential for effective recovery.
