To determine the effect of altitude of residence on influenza A (H1N1).
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.
Adjusted rates for hospitalization and hospital mortality rates increased with altitude, probably due to hypoxemia.
确定居住地海拔高度对甲型 H1N1 流感的影响。
我们分析了新型甲型 H1N1 流感病毒流行初期的 207135 例官方报告的流感样病例、23048 例住院病例和 573 例死亡病例,以确定高原地区居民是否更常出现这些不良结局。
校正后的住院率和住院死亡率随海拔升高而升高,可能与低氧血症有关。
