Understanding waterborne diseases, their spread, and prevention methods is crucial for everyone, especially those living in areas with poor sanitation and water quality concerns. This guide aims to provide you with comprehensive information on these topics, empowering you to take preventive measures and ensure access to safe and clean water for all.
How Do Waterborne Diseases Spread?
It is primarily spread by drinking contaminated water or coming into contact with it. Such contamination can occur due to several factors, such as sewage discharge, agricultural runoff, and natural disasters. Microorganisms, such as bacteria, viruses, and parasites, in the water can cause infections in humans.
Major Causes of Contaminated Water
- Sewage discharge from households and industries
- Agricultural runoff containing fertilisers and pesticides
- Floods and natural disasters that mix sewage with drinking water
Modes of Transmission
- Contact with polluted water during bathing or washing
- Consuming contaminated food prepared with unsafe water
- Drinking contaminated water without treatment
- Poor personal hygiene practices
- Direct contact with infected individuals
