[Chronical of a declared meningococcal meningitis epidemic (Goma, Zaire, August 1994)]

Abstract

The authors relate their experience controlling an epidemic of meningitis which broke out in the refugee camps of the Goma region, in northern Zaire, after the dramatic events which had happened in Rwanda in April and June 1994. Out of the 348 cases of purulent meningitis diagnosed by the Bioforce team, meningococcal etiology was confirmed 327 times. The isolated meningococci were all of the serogroup A, serotype A; 4; P 1,9. They were resistant to streptomycin and to sulphamides. The epidemic lasted one month, touched people of all ages and spread progressively to all the camps. The epidemic surveillance set up meant that vaccination was carried out very quickly and the epidemic brought rapidly under control, even if other factors did intervene. All those called upon to intervene in such a context should be made aware of the interest of the basic triad to fight these epidemics: rapid vaccination, treatment of cases with oily chloramphenicol and bio-epidemiological surveillance.
