For too long, parasitic infections have been underestimated, overlooked, or mistaken for other conditions. One of the most dangerous and widespread parasites is Schistosoma, a blood-dwelling worm that silently wreaks havoc inside the human body. These parasites are not rare. They infect over 200 million people worldwide, and many of their symptoms are misdiagnosed as entirely different illnesses.
How Schistosoma Causes Damage:
Schistosoma worms live in the bloodstream, where they feed, breed, and lay eggs.
Size and reproduction: They can grow up to 20 millimetres in length and survive for years inside the human host. A single pair of worms can release hundreds of eggs every day, leading to tens of thousands of eggs circulating through the body in just weeks.
