Outline of Final Research Achievements

Influenza seasonality in the tropics is poorly understood and not as well documented as in temperate regions. We investigated associations between influenza incidence and weather variability among children under five in a poor urban area of Dhaka, Bangladesh. Acute respiratory illness data were obtained from a population-based respiratory and febrile illness surveillance in a low-income urban area in Dhaka. Time series analysis was conducted to determine associations between the number of influenza cases per week and weather factors. Influenza A had associations with minimum temperature, relative humidity (RH), sunlight duration, and rainfall, whereas only RH was associated with influenza B. Although associations of the other weather factors varied between the two subtypes, RH shared a similar positive association when humidity was approximately 50-70%. Our findings of a positive RH association is consistent with prior studies, and may suggest the viral response in the tropics.
