Volunteer for NIAID-funded clinical studies related to strongyloidiasis on ClinicalTrials.gov.
People become infected when they come in contact with soil containing the roundworms. After a short feeding period and development in the soil, the larvae penetrate human skin, enter the blood stream, and pass through the right side of the heart to the lungs. From the lungs, the parasites go up the windpipe into the mouth, are swallowed, and reach the upper part of the small intestine where they develop into mature worms.
