title: [Malaria morbidity in adults living in urban Burkina Faso].
abstract: Urbanization in countries located in areas of endemic malaria can decrease the level of immunization and make malaria a more serious public health problem in adults. The purpose of this prospective study was to describe the clinical and parasitological features of malaria in adults in the city of Bobo Dioulasso in Burkina Faso. Study was carried out between July and November 1992 at the medical testing laboratory of the Muraz Center in 494 patients including 378 adults and 116 children under the age of 15 years. The parasitic index was 23% in adults as compared to 62% in children. There was not a significant difference in the parasitic index according to whether the place of residence was located in the city center or outlying suburbs. Parasite density ranged from 6 to 145,000 parasites per mm3 in adults as compared to 6 to 426,000 parasites per mm3 in children. Median parasitemia was 696 parasites per mm3 in adults as compared to 8800 per mm3 in children. The threshold of parasitemia for appearance of clinical symptoms was thus lower in adults than in children. Because of the poor positive predictive value of the main clinical features and the high incidence of self-treatment, microscopic examination is indispensable to confirm diagnosis of malaria. The results of this study indicate that urbanization in the city of Bobo Dioulasso has not significantly changed the level of immunization to malaria in adults.
