ABSTRACT
Setting: Karatu; Ngorongoro; Babati; Mbulu and Hanang districts in Arusha and Manyara regions; Tanzania. Methodology: A retrospective study was conducted in Karatu; Ngorongoro; Babati; Hanang and Mbulu districts in Arusha and Manyara regions between July and September 2002. Review of Hospital records and interview with district medical officers; hospital Incharge and clinicians were conducted.Results: Out 170;345 patients who attended hospitals in Babati; Dareda; Karatu; Hydom; Katesh; Wasso; Endulen and Mbulu hospitals in the year 2001; 619(0.36) were diagnosed as having brucellosis. It was found out that women suffer from brucellosis more than males. Out of 619 cases of brucellosis reported in the year 2001; 432 (69.8) were females and 187(30.2) were males. Most of the patients were of the age between 16-35 (46.3) i.e. after school age compared to the middle aged 36-50 (30.4). Few cases were found in the pre school age (7 years); school age (7-15) and old age (50 years) Conclusion There is a need to carry out a study that will establish the burden caused by brucellosis in the area. This should also include investigating the relationship between infection in animals and that in humans. There is also a need to investigate the burden of the disease to the community as well and not only to those who attend hospitals. Factors that favor acquisition of brucellosis to animals and subsequent transmission to humans must be explored and pointed out clearly so that the communities can be made aware of and hence minimize the chances for transmission of brucellosis
