To relate the number of ambulatory consultations, emergency and hospital admission due to AB with climatic factors and air pollution. Patients of less than 1 year old with AB that consulted to outpatient clinics, the emergency room or were admitted to the Pediatrics ward of the Catholic University Hospital, were enrolled. Information about respiratory syncytial virus (RSV) was obtained from the Catholic University Medical Investigation Center. Indices of air pollution such as particulate matters of less than 10 microns/m3 (PM 10), of less than 2.5 microns/m3 (PM 2.5), CO, SO3 and O3 were obtained from the Metropolitan Environmental Service. Temperature, humidity and precipitations were obtained from the Chilean Meteorological Service. Ninety nine consultations in out patient clinics and 442 in emergency rooms were collected (55% male, mean age 4.8 months). One hundred fif...
