Hygiene is one of the main indices for socio-cultural development of any country. Better hygiene result in improving of health, reduces child mortality, and improve water quality, environment, and economic growth of a country. Diarrheal diseases persist to be a major threat to child health in developing countries around the world. The latest estimate published by the World Health Organization show that diarrheal disease is responsible for approximately 800,000 deaths of children under the age of five per year, cause a higher number of under-age-5 deaths than malaria and HIV combined.One of the key factors contributing to the frequency and burden of diarrheal disease is the pronounced lack of water and sanitation in a majority of developing countries. According to the United Nations report, more than half of the population in developing countries still lacks access to the basic form of sanitation. Some progress has been made in the water sector, but 21% of the population in developing countries still have not access to safe drinking water. The situation is most rigorous for Sub-Saharan African countries, where 63% of the population lacks access to basic sanitation and 45% of the population lacks safe drinking water supply.
Water and sanitation are among the precedence of the world. The United Nation’s Millennium Development Goals (MDGS) reduce half number of people without sustainable access to safe drinking water and basic sanitation by the year 2015. The Government of Malawi includes water and sanitation in its developmental agenda.
