A crash course in changing the world.
Did you know that diarrheal disease accounts for an estimated 4.1% of the total global burden of desease and is responsible for deaths of 1.8 million people every year, all over the world?
In 88% of all these cases, the development of diarrhea is due to usage of insufficiently purified water, often contaminated with feces, urin or other agents.
Second problem are bad water supply systems, and also poore hygiene of people. This is very common in developing countries of Africa, and unfortunately most of victims are children.
Water filtering systems
Investing in new, more efficient systems for transport of water, in units for filtering smaller quantities of water for villages in remote regions is infrastructural base for rising the awarenes in the minds of people about importance of using the pure, filtered water as a basic "tool" for prevention of deadly diseases.
Infectious diseases are caused by pathogenic microorganisms. Pathogenicity stands for a potential of certain microorganism to induce the development of desease in it`s host (humans, animals).
Types of infections:
Contamination of water with sewage
One of characteristic signs of schistosomiasis - destended belly.
Prevention: usage of pure water (filtering), usage of chemicals for killing the Copepodes.
Risks: Secondary bacterial infections (tetanus) - poore health care in developing countries.
Facts: 200 million (worldwide) every year, 200 000 deaths.
Location: Sudan, Ghana, Mali, Ethopia (endemic countries). Total eridication (destruction) of worms is possible (trough behaviour change) because every generation of worms need a human host for development every year, and there is no known animal or enviromental reservoir of worms.

Summary: Infectious diseases are caused by infectious microorganisms or worms. Source of these pathogens are dirth and with feces and urin contaminated water (sewer). Prevention is building efficient water filetring systems and usage of chemicals for desinfection of water. Usage of available vaccines and infection preventive drugs. Education of people about general hygiene.
