Before examining the harmful diseases that are caused due to water pollution, let us classify the microorganisms that have been identified as one of the primary causes of such harmful diseases.

Bacteria

Water is a natural home for different types of bacteria and E. coli 0157 H7 is considered the most harmful of all the disease-causing bacteria that have been identified. It produces toxins that can destroy human intestinal cells and also anemia.

Viruses – Hepatitis A and Norwalk Virus

A virus is said to be inactive if it is free from a living host cell, but it survives even in severe environmental conditions. Once they are able to find a living host, they become active and capable of rapid reproduction, which infects the cells of the attached host. Viruses have only one type of nucleic acid (DNA) and can survive at room temperature while attached to human hands, food and objects. Hepatitis A virus is one of its type that gets transmissible through stool contamination or fecal and spreads in places with lack of proper sanitation or observance of personal hygiene.

Another harmful and common type of viral pathogen is the Norwalk Virus that becomes active during winter as it causes ‘stomach flu” or the “Winter Vomiting Disease”. The name Norwalk was taken from Norwalk, Ohio, the place where the virus was first identified in link with the outbreak of waterborne diseases.

Protozoa

Protozoa is commonly found in large bodies of water and have been recognized to be larger in size than the bacteria and viruses. They can survive in the toughest environmental conditions due to their ability to hide a cystic covering that provides them protection from water disinfectants.
