Air pollution has become the greatest health concern in our world, especially in respiratory diseases. The concentration of particulate matter of size less than or equal to 2.5 in micrometer (PM2.5) in Addis Ababa is higher than that of the 2021 WHO guidelines limit of the annual average of 5μg/m3 and a daily average of 15 μg/m3 for the last four years of the study period. US EPA controlled single air quality monitor data of PM2.5 concentration for location Addis Ababa-Central is obtained from and it is used with meteorological data for analysis of health effect. Poisson Generalized Additive Model (GAM) is utilized for the analysis of variables under study from January 1, 2018, to December 31, 2021, in Addis Ababa, Ethiopia. In this study, statistically significant association between fine particulate matter (PM2.5) and acute upper respiratory infection hospital admission in Addis Ababa city and its health effect is observed. Relative risk of acute upper respiratory infection hospital admission associated with 10 μg/m3 increase in PM2.5 concentration was 1.08 (95% CI: 1.06-1.11). We have also observed a positive effect of relative humidity and precipitation on respiratory infection. Therefore reducing the pollutant concentration in the city needs due attention to help people from difficulty in breathing.
