Abstract

Objective: To determine the effect of altitude of residence on influenza A (H1N1).

Materials And Methods: We analyzed 207 135 officially notified of influenza-like illness (ILI) cases, 23 048 hospitalizations and 573 deaths during the first months of the novel pandemic influenza A H1N1 virus, to examine if residents of high altitude had more frequently these adverse outcomes.

Results: Adjusted rates for hospitalization and hospital mortality rates increased with altitude, probably due to hypoxemia.
