to fight. This left them traumatised, with an estimated 400,000 people (by 2009) being mentally ill. Thousands of former child soldiers have fallen into substance abuse as they try to blunt their memories. Potable water supply The water supply in Sierra Leone is characterised by limited access to safe drinking water. Despite efforts by the government and numerous non-governmental organisations, access has not much improved since the end of the Sierra Leone Civil War in 2002, stagnating at about 50% and even declining in rural areas. It is hoped that a new dam in Orugu, for which China committed financing in 2009, will alleviate water scarcity. According to a national survey carried out in 2006, 84% of the urban population and 32% of the rural population had access to an improved water source. Those with access in rural areas were served almost exclusively by protected wells. The 68% of the rural population without access to an improved water source relied on surface water (50%), unprotected wells (9%) and unprotected springs (9%). Only 20% of the urban population and 1% of the rural population had access to piped drinking water in their home. Compared to the 2000 survey access has increased in urban areas, but has declined in rural areas, possibly because facilities have broken down because of a lack of maintenance. With a new decentralisation policy, embodied in the Local Government Act of 2004, responsibility for water supply in areas outside the capital was passed from the central government to local councils. In Freetown, the Guma Valley Water Company remains in charge of the water supply. 2014 Ebola outbreak Ebola is prevalent in Africa where social and economic inequalities are common. The central African countries are the most prevalent of EVD; like the Democratic Republic of Congo, Sudan, Uganda, and Gabon In 2014 there was an outbreak of the Ebola virus in West Africa. As of 19 October 2014, there had been 3,706 cases of Ebola in Sierra Leone, and 1,259 deaths, including that of the leading physician trying to control the outbreak, Sheik Umar Khan. In early August 2014 Guinea closed its borders to Sierra Leone to help contain the spreading of the virus, which originated in Guinea, as more new cases of the disease were being reported in Sierra Leone than in Guinea. Aside from the human cost, the outbreak was severely eroding the economy. By September 2014,
