According to traditional African beliefs, disability is a curse, therefore some parents are ashamed to produce a disabled child. The children are often hidden away, physically and sexually abused, and some even killed. The majority of children become disabled in Africa due to conflict, accidents, and a lack of immunisation against diseases such as polio and measles. Many people cannot afford mosquito nets and so cerebral malaria is also common. One in ten African children are disabled and 98% of them are not in education. There are very few vocational schools and those that do offer boarding facilities are very expensive due to the fact that the government does not allocate any money to challenged learners. Matumaini is a unique boarding school in Tanzania that is run by a charity, here the children are able to get an education and the medical support that they need.
