【摘要】 目的探讨流行性感冒(下称流感)高峰与温度和相对湿度之间的关系。方法对香港地区1998-2002年的流感求诊比率及4年来温度和相对湿度的数据进行统计学分析,得出流感高峰与温度、相对湿度间的联系。结果周平均温度低于20℃时,有发生流感高峰的可能;周平均温度降至15℃以下,有发生流感高峰的较大可能。在周平均温度较低且相对湿度较高的情况下,体感温度比实际预报的温度低,也有发生流感高峰的可能。结论香港的流感在一年四季都会发生,但主要的高峰期发生在低温(15℃以下)或低温高湿的天气状况下。更多还原

【Abstract】 Objective To discuss the relation between influenza peak, temperature and relative humidity. Methods Statistical analysis on the data of influenza consultation rates, temperature and relative humidity from 1998 to 2002 in Hong Kong area was carried out to propose some relation between influenza peak, temperature and relative humidity. Results It was slightly possible to cause influenza peak when the week-averaged temperature was less than 20 ℃ and largely possible to cause influenza peak when the week-averaged temperature was less than 15 ℃. It was also largely possible to cause influenza peak when the week-averaged temperature was very low and the relative humidity was higher which resulted the lower body-sense temperature compared with the forecasting temperature. Conclusion The prevalence of influenza occurs during four seasons in one year in Hong Kong, but the prevalence peak of influenza mainly appears under the condition of lower temperature(<15 ℃) weather, lower temperature-higher relative humidity weather.更多还原
