approximately 11.5 million cases of clinical malaria in 2008. In 2007–08, malaria prevalence among children aged 6 months to 5 years was highest in the Kagera Region (41.1 per cent) on the western shore of Lake Victoria and lowest in the Arusha Region (0.1 per cent). According to the 2010 Tanzania Demographic and Health Survey 2010, 15 per cent of Tanzanian women had undergone female genital mutilation (FGM) and 72 per cent of Tanzanian men had been circumcised. FGM is most common in the Manyara, Dodoma, Arusha, and Singida regions and nonexistent in Zanzibar. The prevalence of male circumcision was above 90 per cent in the eastern (Dar es Salaam, Pwani, and Morogoro regions), northern (Kilimanjaro, Tanga, Arusha, and Manyara regions), and central areas (Dodoma and Singida regions) and below 50 per cent only in the southern highlands zone (Mbeya, Iringa, and Rukwa regions). 2012 data showed that 53 per cent of the population used improved drinking water sources (defined as a source that "by nature of its construction and design, is likely to protect the source from outside contamination, in particular from faecal matter") and 12 per cent used improved sanitation facilities (defined as facilities that "likely hygienically separates human excreta from human contact" but not including facilities shared with other households or open to public use). Women Women and men have equality before the law. The government signed the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) in 1985. Nearly 3 out of ten females reported having experienced sexual violence before the age of 18. The prevalence of female genital mutilation has decreased. School girls are reinstated back to school after delivery. The Police Force administration strives to separate the Gender Desks from normal police operations to enhance confidentiality of the processing of women victims of abuse. Most of the abuses and violence against women and children occurs at the family level. The Constitution of Tanzania requires that women constitute at least 30% of all elected members of National Assembly. The gender differences in education and training have implications later in life of these women and girls. Unemployment is higher for females than for males. The right of a female employee to maternity leave is guaranteed in labour law.
