What is the mode of transmission of schistosomiasis?
How can I get schistosomiasis? Infection occurs when your skin comes in contact with contaminated freshwater in which certain types of snails that carry schistosomes are living. Freshwater becomes contaminated by Schistosoma eggs when infected people urinate or defecate in the water.
Can you catch a parasite from another person?
the parasite might be spread to other people through exposure to an infected person's blood (for example, by blood transfusion or by sharing needles or syringes contaminated with blood).
How long can schistosomiasis live in the body?
Schistosomes live an average of 3–10 years, but in some cases as long as 40 years, in their human hosts. Adult male and female worms live much of this time in copula, the slender female fitted into the gynaecophoric canal of the male, where she produces eggs and he fertilises them (appendix).

How can schistosomiasis be controlled?

Where is Schistosoma found in the body?
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine.

- boil or filter water before drinking – as the parasites could burrow into your lips or mouth if you drink contaminated water.
What causes urinary schistosomiasis?
Urinary schistosomiasis is caused by S haematobium and deposition of eggs in the bladder and ureters. The subsequent granulomatous inflammation causes nodules, polypoid lesions, and ulcerations in the lumens of the ureter and bladder, which in turn causes urinary frequency, dysuria, and end stream haematuria.
Where is schistosomiasis endemic in the Philippines?

What are two ways Chagas disease can be spread?
Chagas disease can be transmitted in five different ways: by a vector (through the faeces of an insect), through vertical or congenital transmission (from mother to her child during pregnancy), by way of blood transfusions or organ transplants, by ingesting contaminated food or drinks, or because of laboratory ...
