The cost of treatment for HIV is so high that many families often do not have the means to pay for the care or education of the child. If a child is forced to drop out of school in order to take on additional responsibility at home due to the illness of his parent, the child is named a "de facto" orphan. There has been no correlation found between gender and risk of poor educational outcomes or risk of dropping out of school. Because of stigma, many HIV/AIDS affected orphans are expelled from school.
