Abstract
Objective. Analysis of the malaria epidemic situation in the Republic of Guinea and identification of the main factors determining its spread in North-West Africa.
Materials and Methods: Data from the National Agency for Health Safety the Republic of Guinea (Agence Nationale de Sécurité Sanitaire) and meteorological observations in regions of Guinea with different natural and climatic conditions were analyzed.
Results. The Republic of Guinea is located in the subequatorial climate zone, and malaria vectors — Anopheles gambiae complex are widespread within its territory. In the forested region of Guinea, the amount of warmth is sufficient to complete plasmodia sporogony within an average of 14 days. The year-round incidence rate in the analyzed territories is 24.3 per 1,000 inhabitants, which corresponds to 39.9% of the average annual level. The epidemiological year is characterized by a seasonal increase in incidence, which lasts 4–6 months, from June to November or December. The maximum average monthly rates are recorded in August.
Conclusion. Malaria foci are characterized by a diversity of parasitic systems in different natural zones and the widespread distribution of Pl. falciparum. Based on physical and geographical conditions, the republic’s territory can be divided into four climatic and natural regions, differing in their degree of malariogenicity.
