Freshwater parasites of humans
Freshwater plays as a carrier medium of disease-carrying parasites for the people a big role. The water serves as a transport medium for the pathogens themselves or as a habitat for intermediate hosts . The parasite is usually incorporated through oral ingestion , breaking the skin barrier through a larval form of the parasite, or consuming an intermediate host.
Especially due to a direct supply of drinking water from the waters in combination with the lack of sanitary facilities, the corresponding parasitoses spread. The supply of the world population with hygienically and toxicologically safe water as well as hygienically impeccable wastewater disposal will therefore represent one of the greatest challenges facing mankind in the coming decades ( water crisis ).
