But there is another danger - wild animals. Agnes, who lives in Malawi, has a terrible story to tell of the day she was attacked by a crocodile.

"When the crocodile caught me, I started screaming as it was trying to pull me into the water, and then my two sons rushed into the river – they had a spear in their hands and they put this into the crocodile's mouth so it eventually released me.It has left her with a terrible injury, unable to work, and terrified of fetching water. Fortunately her village is one where WaterAid has installed a safe water point. Not only are the risks of disease reduced enormously, people no longer have to risk meeting a rogue elephant along the way, or a crocodile by the water. Children now have time to go to school, and women can work.
"Then they rushed me to the hospital as my hand was broken. I had a deep wound here, so I had to go back to the hospital three times to try and get them to repair it."
