title: [An outbreak of Schistosoma mansoni bilharziasis. 113 cases in a military unit returning from Central Africa].
abstract: The authors report on an outbreak of Schistosoma mansoni infestation involving 113 military men who had been contaminated together in a tributary of the Chari river in the Central African Republic. The patients were examined on their return to France 50 days after being contaminated and were compared with a control group of 25 subjects who had lived in Africa under the same conditions but were exempt of bilharziasis. All were subjected to a retrospective questionnaire, physical examination, examination of the faeces and serological test for bilharziasis by indirect haemoagglutination. All received two courses of praziquantel. Follow-up serology was performed after 1 year in 86 cases. The results of this study in both groups are presented and commented upon. With intestinal bilharziasis, prophylaxis against contamination is extremely difficult to carry out in endemic areas among people who visit and work "on the spot". Detection by routine serology must be performed upon return.
