Roundworm infections in humans are primarily caused by ingesting roundworm eggs or larvae. These parasitic worms, part of the nematode family, can be contracted through contaminated soil, food, or water. The most common species that infect humans include Ascaris lumbricoides, hookworms, and Trichinella spiralis.
Ingestion of Ascaris eggs from unwashed vegetables or drinking water contaminated with feces is a common way people become infected. Once ingested, the eggs hatch into larvae in the intestines. These larvae then penetrate the intestinal wall and travel to the lungs through the bloodstream. After maturing in the lungs, the larvae move to the throat, where they are swallowed, returning to the intestines to develop into adult worms.
Hookworms, on the other hand, infect humans through direct contact with contaminated soil. The larvae penetrate the skin, usually through the feet, and enter the bloodstream, migrating to the lungs and intestines, similar to Ascaris. Used Fenbendazole for Roundworms Infection.

Another type, Trichinella, infects humans through the consumption of undercooked meat, particularly pork, that contains larvae. Once consumed, the larvae invade the intestines and later spread to muscle tissues.
Symptoms of roundworm infections include abdominal pain, diarrhea, and respiratory issues. Severe cases can cause malnutrition, intestinal blockages, or organ damage. Preventing roundworm infections involves good hygiene practices, proper sanitation, and cooking meat thoroughly. Regular deworming in areas with poor sanitation can also reduce infection rates.
