Larva that strikes hard on the population in countries like Egypt and Sudan, as well as many other countries around the world.
The disease Bilharziasis comes from a flatworm that lives inside a freshwater snail. While this lives inside the host, it multiplies; after it has left the host, the larva can penetrate human skin in less than 1 minute. The larva grows inside the human body, and in its mature stage it stays in the veins around the intestines or bladder. Here it mates with other bilharziasis worms. The eggs either stay in the body, or leave with the urine, entering freshwater, where the cycle starts over again.
The diseases coming from the bilharzia, are called bilharziasis. Today the word 'schistosomiasis' is the one commonly used. There are three types of bilharziasis: Schistosoma haematobium, Schistosoma mansoni and Schistosoma japonicum.
The Schistosoma haematobium is predominant in Egypt. The male is about 1,5 cm long, the female a bit longer, and thinner. The most common effect on humans is severe inflammatory reaction in the walls of the bladder and hemorrhages.
The effect of bilharzia is often death unless treated, and until 1982 no satisfying medicine existed. The drug Praziquantel has since then proven to be very effective. Many countries where bilharzia is a major problem do not have the economy to provide people with instruction and drugs, so that the risk of being contaminated remains very high.
