[Human trypanosomiasis focus of Vavoua (Ivory Coast). A clinical, parasitological and sero-immunological survey (author's transl)].
Vavoua human trypanosomiasis focus, located 60 km north of Daloa (Ivory Coast Republic) is facing a period of hyperactivity. A medical survey has been conducted in 9 villages of this focus: 7.424 persons have been examined and 128 new cases diagnosed in the field after clinical and parasitological examinations. Indirect Fluorescence Antibody Test applied to dried blood blots, in the laboratory, revealed 266 immunological suspects to be reexamined. 185 suspects were reexamined, 104 of whom were diagnosed after tyrpanosomes had been found in blood or/and in gland juice. The microhaematocrit centrifuge technique gave good results. Most of the 232 new cases were in the classical first period (unaltered CSF). Authors are insisting on the importance of survey prospections allowing an early diagnosis of sleeping sickness and on the interest of an immunodiagnostic test in addition to classical techniques to diagnose asymptomatical forms.
