After a short epidemiological description on the malaria situation in the Grande Comoro Island, the authors fix the threshold of the pyrogenic parasite density. The studies carried out in out-patients and a pediatric in patients department allowed the authors to assess the place of malaria in the pathology. Second motive for seeking medical advice for fever in children, malaria is the first cause of dead in hospitalized children between 1 and 4 years. The morbidity and mortality decreases rapidly from the age of five and the limit seems to be reached at the age of 10. Perennial transmission does not result in seasonal variation of the morbidity although the prevalence, in active detection, of malaria infection is significantly higher in the raining season than in the dry season.
