6. Recreational uses of water such as public swimming make lakes, oceans, 
rivers carry infection agents and result a number of health.

The four main types of diseases Caused by Contaminated water are: 
▪ Water borne diseases, are caused by the ingestion of water contaminated by 
human or animal faces or urine containing pathogenic bacteria or viruses. 
These diseases include cholera typhoid, amoebic and bacillary dysentery and 
other diarrheal diseases. 
▪ Water-washed diseases are caused by poor personal hygiene and skin or eye 
contact with contaminated water. These diseases include scabies, trachoma 
and lice and tick-borne diseases. 
▪ Water-based diseases, which are caused by parasites found in intermediate 
organisms living in water. These diseases include round worm, dracunculiasis 
schistosomiasis and other helminths.

▪ Water-related diseases, which are caused. by insect vectors which breed in 
water. These diseases include dengue, malaria, and yellow fever. 
 
Prevention of water pollution 
▪ Government should set standards to keep drinking water safe and have the water 
tested.  
▪ Put firm laws and regulation to control water pollution. 
▪ Sewage, industrial and agricultural wastewater treatment. 
▪ Maintain safe and enough water for all population.    
▪ Educate public: take advantage of opportunities to speak about pollution. This 
is a perfect opportunity to educate others about the need to protect water and 
environment. 
4- Food supply: 
Good nutritious food is necessary for good health. The quality of food is affected by 
the environment. 
Access to enough safe and nutritious food is key to sustaining life and promoting good 
health. Unsafe food containing harmful bacteria, viruses, parasites or chemical 
substances can cause more than 200 different diseases, ranging from diarrhoea to 
23 
 
 
 
cancers. Around the world, an estimated 600 million – almost 1 in 10 people – fall ill 
after eating contaminated food each year, resulting in 420 000 deaths and the loss of 
33 million healthy life years (DALYs). 
Food safety, nutrition and food security are closely linked. Unsafe food creates a 
vicious cycle of disease and malnutrition, particularly affecting infants, young 
children, elderly and the sick. In addition to contributing to food and nutrition security, 
a safe food supply also supports national economies, trade and tourism, stimulating 
sustainable development. The globalization of food trade, a growing world population, 
climate change and rapidly changing food systems have an impact on the safety of 
food. WHO aims to enhance the capacity to prevent, detect and respond to public 
health threats associated with unsafe food at the global and country levels. 
Characteristics of healthy foods: 
Healthy foods typically have the following features: 
1. Nutrient-Rich: They provide essential nutrients like vitamins, minerals, protein, 
and fiber. 
2. Low in Processed Sugar: Healthy
