INTRODUCTION: Air pollution would increase the risk of severe infection repiratory in pediatrics. OBJECTIVE: Review impact of air pollution visits for severe infection repiratory in effectors of Buenos Aires City Government. METHOD: Ecologic research, time-series. Research Sources: Environmental Protection Agency, National Meteorological Service and Integral Health History of the Hospital Management System. Population: Patients under 2 years old who consulted for severe infection repiratory in effectors of Buenos Aires City Government and lived commune with continuous environmental monitoring during 2018.

To select in the data base the visits to analyze an operative definition was made. RESULTS: 80.287 visits were registered, 24.847 for severe infection respiratory (30%).

The numbers of visits for severe infection respiratory was higher during cold months than warm months. (19,9% vs 11,9%; RR:1,67 [1,61-1,72]). CONCLUSION: average values of PM(10) and NO(2) show correlation with the numbers of total visits and visits for severe infection respiratory. The visits increase during winter.
