Schistosomiasis Transmission

Facts about the transmission of schistosomiasis:

  • Schistosoma parasites live in fresh water snails, in the tropics and subtropics.
  • Young parasites are present in contaminated water.
  • The parasite burrows into the skin of humans who enter the water.
  • The parasite migrates to the lungs and liver where it matures into the adult form.
  • The adult moves through the bloodstream to:
    • Bladder
    • Intestines
    • Rectum
    • Liver
    • Lungs
    • Spleen
  • The adults produce eggs.
  • Eggs are released by the body in the urine and stool.
