Originally, fecal contamination was determined with the presence of coliform bacteria, a convenient marker for a class of harmful fecal pathogens. The presence of fecal coliforms (like E. Coli) serves as an indication of contamination by sewage. Additional contaminants include protozoan oocysts such as Cryptosporidium sp., Giardia lamblia, Legionella, and viruses (enteric). Microbial pathogenic parameters are typically of greatest concern because of their immediate health risk.

If pathogens are present in drinking water, they can cause waterborne diseases such as diarrhea, cholera, and typhoid fever when consumed. It is important to treat contaminated water to eliminate these pathogens before consumption to prevent illness.
It can be caused by drinking alcohol
caused by drinking contaminated water.
disentery
Dysentery is caused by bacteria in bad drinking water.
amebic dysentery
caused by drinking contaminated water.
The common cold is caused by a virus and is not caused by drinking water on an empty stomach early in the morning.
Waterborne diseases in the Nile River include cholera, typhoid fever, and schistosomiasis. These diseases are primarily caused by pathogens such as bacteria, viruses, and parasites present in contaminated water. Poor sanitation, inadequate water treatment, and agricultural runoff contribute to the proliferation of these pathogens in the river. Consequently, communities relying on the Nile for drinking water are at significant health risks.
Chlorine is often used in water purification to kill bacteria, viruses, and other pathogens that can cause waterborne illnesses. It helps make the water safe for drinking by effectively disinfecting it.
Lack of water in the body is caused when more water leaves the cells than is replaced by drinking water and eating water rich foods.
sounds like dysentery.
