Influenza poses a global health threat. The disease affects all ages, often with variable clinical features.
Abidjan, where this study took place, has a long rainy season April-July with a shorter less intense rainy season October-November. Temperatures vary very little during the year. In temperate areas, children and adults aged >=65 years are risk groups. In these countries the seasonality of influenza is clearly defined, with seasonal epidemics in cold weather periods. But in the tropics, the risk groups of influenza are not as well defined. Also, the dynamics of influenza transmission and climatological parameters that influence it are specific to the tropical region and not as thoroughly studied.
Objective
This study aims to determine the epidemiological and clinical profiles of influenza infections related to different strains and the effect of climatological parameters on the temporal distribution of the disease for the prediction.
