Water pollution is a global health concern, particularly in developing countries where access to clean water remains limited. Contaminated water poses a severe risk, leading to various illnesses and long-term health issues. Diseases arising from polluted water sources, such as rivers, lakes, or even groundwater, are preventable and still present due to a lack of infrastructure and sanitation. In this article, we will explore the most common diseases of water pollution, how they spread, the pollutants responsible, and preventive measures.

1. Cholera

One of the most common diseases caused by water pollution, cholera is an acute intestinal infection caused by Vibrio cholerae. It spreads through drinking contaminated water and causes severe diarrhea, and dehydration, and, if untreated, can be fatal. Cholera outbreaks are common in regions with poor sanitation and limited access to clean water.

2. Diarrheal Diseases

Diarrheal diseases, often caused by bacteria, viruses, or parasites in polluted water, are a leading cause of death, especially among children. Contaminated drinking water, poor hygiene, and lack of sanitation contribute to these illnesses. Diarrhoea can lead to severe dehydration, making it one of the most harmful diseases.

3. Typhoid Fever

Caused by Salmonella typhi, typhoid is a bacterial infection that spreads through contaminated water diseases. Symptoms include prolonged fever, stomach pain, and fatigue. If untreated, it can lead to severe complications or even death. Typhoid is common in areas where water contamination from sewage is rampant.

4. Arsenicosis

Prolonged exposure to arsenic in drinking water can lead to arsenicosis, a chronic condition that causes skin lesions, cancer, cardiovascular disease, and other severe health issues. This contamination is more common in regions where groundwater is polluted with naturally occurring arsenic or from industrial waste.

5. Giardiasis

Giardiasis is a parasitic infection caused by Giardia lamblia, which spreads through water contaminated by faecal matter. This parasite affects the small intestine, causing diarrhoea, cramps, and nausea. The disease is one of the most common illnesses caused by water pollution, particularly in areas lacking proper water treatment facilities.

6. Dysentery

Dysentery is caused by bacteria or amoebas from contaminated water, leading to severe diarrhoea with blood or mucus. This disease, often associated with poor hygiene and water quality, is a significant cause of illness in developing nations.

7. Hepatitis A

A viral infection affecting the liver, hepatitis A is transmitted through the consumption of contaminated food or water. Symptoms include fever, fatigue, jaundice, and abdominal discomfort. Vaccination and proper water sanitation are critical in preventing the spread of hepatitis A.

Several pollutants are responsible for the spread of diseases caused by water pollution. Understanding these contaminants can help in prevention efforts.

• Bacterial Contaminants: Bacteria such as Escherichia coli (E. coli), Salmonella, and Vibrio cholerae are common in fecal-contaminated water and lead to gastrointestinal diseases.
• Viral Contaminants: Viruses like hepatitis A and norovirus are often found in polluted water and cause a range of symptoms from gastrointestinal problems to liver inflammation.
• Parasitic Contaminants: Parasites like Giardia thrive in polluted water and are difficult to eliminate, causing significant health problems.
• Chemical Contaminants: Industrial runoff introduces harmful chemicals, including pesticides, fertilizers, and heavy metals (such as lead and arsenic), into water supplies, leading to both acute and chronic health issues.

The illnesses caused by water pollution lead to long-term health complications. Prolonged exposure to contaminated water can result in:

• Chronic conditions: Kidney damage, liver failure, and even cancer due to heavy metals and toxic chemicals.
• Reproductive issues: Chemicals in polluted water can affect reproductive health, causing fertility problems and birth defects.
• Increased vulnerability in children and the elderly: Children under five and the elderly are at higher risk for severe complications from waterborne diseases.

Preventing contaminated water diseases starts with reducing pollution at its source and ensuring safe drinking water practices. Here are some preventive measures:

• Proper Waste Disposal: Dispose of chemicals, oils, and medications properly to prevent them from entering water sources.
• Community Clean-up Efforts: Participate in local clean-up drives to reduce litter and pollutants in nearby rivers and lakes.
• Safe Sanitation Practices: Ensure that sewage systems and water treatment plants are maintained and functioning properly to prevent water contamination.

While preventive measures are essential, protecting yourself from the financial impact of diseases of water pollution is equally important. Comprehensive health coverage can help mitigate the costs of treatment for waterborne diseases, ensuring timely and quality care. SBI General Insurance offers reliable medical insurance plans that cover a wide range of illnesses, including those caused by water pollution. With the right insurance plan, you can safeguard your family's health and well-being against unforeseen medical expenses.

Q1. What are the effects of waterborne diseases?

Waterborne diseases primarily cause gastrointestinal issues, but prolonged exposure can lead to chronic health problems, including liver and kidney damage, reproductive issues, and cancer.

Q2. How do diseases spread through water?

Diseases spread through water when it becomes contaminated with bacteria, viruses, or chemicals, often from sewage, industrial runoff, or agricultural waste.

Q3. What are the most common waterborne diseases in India?

Cholera, typhoid, and hepatitis A are some of the most common waterborne diseases in India, primarily affecting regions with poor water sanitation.

Q4. What are the major effects of water pollution?

Water pollution causes diseases, disrupts ecosystems, harms wildlife, and limits access to clean water. It also leads to toxic buildup and economic losses, highlighting the need for urgent action.
