Material and Methods: A daily registry of all consultations of patients older than 15 years old in seven public primary care centers, was carried out between January 2003 and December 2008. Consultations were classified as having non-respiratory or respiratory causes. The latter were broke down in upper or lower respiratory diseases, pneumonia, chronic obstructive pulmonary disease (COPD) and asthma. Results: A total of 1,170,941 consultations were registered and 19% were due to respiratory diseases. Of these, 46% were due to upper respiratory diseases, 31% due to lower respiratory diseases, 8% due to COPD, 6% due to pneumonia, 5% due to asthma and 4% due to other respiratory causes.
