Diarrhoea kills some 194,000 children under five every year in Nigeria, the United Nations Children Fund (UNICEF) has said.
This was contained in a message issued by UNICEF to mark this year's Global Hand washing Day saying "hand washing is not complicated, but crucial."
UNICEF also emphasizes that the simple act of hand washing with soap can save hundreds of thousands of children who needlessly die every year.
According to the message, "As diarrhoea diseases are basically faecal-oral in nature, one of the simplest and most inexpensive barriers to infection is hand washing with soap or ash at critical times, such as before handling food and after defecation or changing a diaper. Hygiene promotion and proper hand washing is also the most cost effective public health intervention against diarrhoea diseases."
Ibrahima Fall, Representative of UNICEF in Nigeria said, "Hand washing with soap has become all the more necessary in view of the ongoing floods in a number of states contaminating water supplies."
