目的研究医院病人痰标本分离出曲霉菌量与雾霾天气的相关性。方法通过回顾性调查,利用当地气象局的气象数据,对某医院2012年1月、12月与2013年1月分3次比较分析了病人痰标本曲霉菌检出率与雾霾天气相关性。结果 2012年1月和12月2个月,该医院病人痰标本曲霉菌检出率分别为4.93%和4.46%,同期雾霾天气发生率分别为3.23%和3.33%。2013年1月,该医院病人痰标本曲霉菌检出率为18.83%,相应雾霾天气发生率为22.58%。结论病人痰标本中曲霉菌检出率与雾霾天气发生率变化趋势一致。
Objective To study the correlation between the quantity of Aspergillus isolated from sputum samples of hospital patients and the hazy weather. Methods A retrospective survey was conducted to analyze the correlation between sputum aspergillus detection rate and smog weather in a hospital from January 2012 to December 2013 and January 2013 using the meteorological data of local weather bureau. Results In January and December of 2012, the positive rates of aspergillus in sputum of patients in this hospital were 4.93% and 4.46%, respectively. The incidence rates of haze were 3.23% and 3.33% respectively in the same period. In January 2013, the sputum specimen Aspergillus detected in this hospital was 18.83%, corresponding to a haze of 22.58%. Conclusion The detection rate of Aspergillus in the sputum of patients is consistent with that of the haze weather.
