      摘要: 全球變暖的大趨勢和不斷增加的輸入病例被認(rèn)為是登革熱在中國重新出現(xiàn)而且流行范圍不斷擴(kuò)大的原因。通過對一些登革熱流行地區(qū)的天氣因素進(jìn)行分析,了解天氣因素與登革熱之間的關(guān)系。廣州、福州和寧波的天氣因素被用于交叉相關(guān)分析,根據(jù)天氣和登革熱疫情的時(shí)間關(guān)系,構(gòu)建了我國登革熱流行的氣象風(fēng)險(xiǎn)地圖。結(jié)果顯示天氣因素對登革熱疫情都存在8~10周的延遲影響。我國登革熱的高風(fēng)險(xiǎn)地區(qū)主要在華南和華東的沿海地區(qū)。華南地區(qū)經(jīng)常暴發(fā)登革熱,華東沿海地區(qū)的南部近年來也多次暴發(fā)登革熱。雖然有些地區(qū)還沒有登革熱流行的記錄,但應(yīng)該加強(qiáng)對輸入性病例的監(jiān)測和管理,防止出現(xiàn)本地流行。

      關(guān)鍵詞: 登革熱, 氣象因子, 全球變暖, 華南地區(qū)

      Abstract: The trend of global warming and the increase in imported cases were supposed to cause the reemerging and expanding of dengue fever (DF) in China. In this paper, the correlation coefficients between meteorological factors and the DF outbreaks in China were analyzed to detect the relationship between weather/climate factors and the outbreak of DF. DF outbreaks in Guangzhou, Fuzhou and Ningbo were selected to investigate the lag effect of weather factors on the outbreaks with the cross correlation analysis. Based on the temporal relationship of weather and DF outbreak, a risk map of DF outbreaks for China with suitable weather factors was drawn. Some weather variables are significantly correlated with the DF outbreaks, at a lagged time period of 8-10 weeks. The risk map demonstrates the risk areas with the climate suitable for the outbreak of DF in China, and coast areas of south and southeast China are included in the risk area.

      Key words: dengue fever, meteorological factor, global warming, South China, coastal region of East China
