what is the relationship between water and disease?
2717
The microbiological quality of drinking-water has been implicated in the spread of important infectious and parasitic diseases such as cholera, typhoid, dysentery, hepatitis, giardiasis, guinea worm and schistosomiasis. Many other diseases are associated with water in other ways.
736534
Contaminated water and poor sanitation are linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. Absent, inadequate, or inappropriately managed water and sanitation services expose individuals to preventable health risks.

A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).

Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year.
835031
Waterborne outbreaks, though infrequent, are usually associated with sewage-contaminated or inadequately treated water. The virus can also be transmitted through close physical contact (such as oral-anal sex) with an infectious person, although casual contact among people does not spread the virus.

Water helps to carry oxygen to your body cells, which results in properly functioning systems. It also works in removing toxins from the body, so drinking more of it could help prevent toxins from building up and having a negative impact on your immune system.

Swallowing this contaminated water can then cause diarrheal illness. Lakes, rivers, and oceans can become contaminated with germs from sewage, animal waste, water runoff following rainfall, fecal accidents, and germs rinsed off the bottoms of swimmers.

Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.

Globally, at least 2 billion people use a drinking water source contaminated with faeces. Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year.

Poor water quality can pose a health risk for people. Poor water quality can also pose a health risk for ecosystems. In the Florida Keys, good water quality is essential to a healthy marine ecosystem. Seagrass and coral reef communities thrive in clean water that is relatively low in nutrients.

Water carries nutrients and oxygen to all cells in the body. Water is required for breathing. Water moistens oxygen for breathing. Water regulates your body temperature.

Drinking or swimming in unclean water can cause: Vomiting or diarrhea. A sick stomach. Skin rashes.

When you don't drink enough water, this is what happens to your body. Water is essential for human life. It accounts for for 50-70 per cent of our body weight and is crucial for most bodily functions. Any deficit in normal body water – through dehydration, sickness, exercise or heat stress – can make us feel rotten.

With no option, they rely on polluted surface and groundwater sources which are also the main sources of water-related disease such as diarrhea, typhoid, cholera, and worm infection. ... In these myriad ways, water is directly linked to poverty – making access to water a means to ending poverty.

Climate change is making heavy intense downpours, droughts and rising water temperatures more common. This can alter the quality of our drinking and recreational water. Bacteria and viruses thrive in these new conditions and when they come into contact with humans, can cause numerous illnesses.
851398
If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.

Drinking enough water is important to keep hydrated on a regular basis, especially when it's cold and flu season. Keep your immunity up by drinking plenty of water to stave off infection. Staying hydrated helps your body naturally eliminate toxins and other bacteria that may cause illness.
