Dja-et-Lobo (Dja and Lobo) department, with Sangmélima its capital. The Beti-Pahuin and other ethnic groups in the South have little traditional political organisational structure. Instead, groups of families are loosely organised into clans under a single patriarch. During the French colonial period, the Bulu formed a tribal union of their various clans. Today, these elders hold little actual power, and most such positions are merely honorary. Education There are 972 schools in the territory. Most of these are located in the area's larger towns and villages. Attendance numbers diminish as one moves into the area's frontiers, particularly the vast, forested areas south of Ebolowa and Sangmélima. Here, students are expected to walk long distances to attend school each day, or else to stay with relatives or alone in towns where schools are located. This problem is not as pronounced at the level of primary school, as these tend to be more widely distributed even in the remoter areas. Nevertheless, all schools in the region tend to be overcrowded. Health Poor sanitation is perhaps the South Region's greatest health hazard. Many villages have no access to running water, and even areas that do have it must contend with outbreaks of amoebic dysentery, bacterial dysentery, brucellosis, giardia, hepatitis A, and schistosomiasis. In 2004, the relatively developed town of Kribi suffered a major cholera epidemic. As it is almost entirely forested, the South supports many disease-carrying organisms. Malaria-bearing mosquitoes are one such pest, and the disease is a major health hazard in the region. Other parasitic diseases found in the South include dengue fever, falariasis, tuberculosis, and typhoid fever. Hospitals and clinics are fairly widespread, but they are mostly located in larger towns and cities. Traditional medicine is thus still the major source of treatment for many of the South's citizens, particularly those in more remote locations. Witchcraft is still blamed for many maladies, including HIV and AIDS in many cases. History Early population movements Archaeological finds in the areas of Kribi and Lobé attest to human presence in the territory of the South Province since prehistory. Of the area's current inhabitants, the earliest to arrive were the Pygmies, who moved in from further south and east in ancient times and lived for centuries as hunter-gatherers in the forests. The Batanga arrived and settled the coastal areas in the 18th century. The Beti-Pahuin Bantu groups entered the area in the 19th century from
