记者１５日从中国疾病预防控制中心获悉，目前中国多数地区流行的流感病毒以甲型Ｈ３Ｎ２病毒为主，少数北方省份以甲型Ｈ１Ｎ１病毒为主，绝大部分病毒没有发生明显变异。专家预计，美国流感疫情不会对中国产生影响，公众无需恐慌。

Reporters from China 15, disease prevention and control center learn,China's most popular area of the influenza virus to influenza H3N2 virus is given priority to,A few northern provinces to H1N1 influenza virus is given priority to,Most of the virus did not happen obvious variation.Experts predict,The flu epidemic will not affect China,Public no need to panic.

　　根据中国疾控中心监测数据，２０１３年第１周，中国北方省份流感样病例占门急诊病例的４．７％，超过前２年的高峰期水平；流感病毒检测阳性率为２１．６％，高于前２年的同期水平，但低于高峰值。南方省份流感样病例占门急诊病例的２．５％，流感病毒检测阳性率为４．９％，均低于前２年同期水平和高峰值。２０１２年，全国共报告流感死亡病例８例（其中甲型Ｈ１Ｎ１流感３例），是２００９年以来报告死亡最低的年份。

According to the centers for disease control and monitoring data,In 2013 the first week,China northern provinces influenza-like cases accounted for 4.7% of the cases of this,More than two years before the peak level;The flu virus detection positive rate was 21.6%,Higher than the previous two years of the level,But below the peak value.Southern province of influenza-like cases accounted for 2.5% of the cases of this,The flu virus detection positive rate was 4.9%,Are lower than the same period in previous two level and peak value.In 2012,,The flu deaths were reported 8 cases(The H1N1 influenza a (3 cases)),Since 2009 the year of death report the lowest.

　　据介绍，２０１３年第１周，美国报告的流感样病例占门诊病人的４．３％，高于过去３年同期水平。目前，马萨诸塞州的波士顿市、芝加哥市和纽约州等先后宣布进入公共卫生紧急状态。

　　专家表示，２０１２年１２月份以来，全国多数省份，尤其是北方地区气温骤降，明显低于往年平均气温，是北方地区呼吸道感染病例上升的主要原因。每年冬季，包括中国、美国和欧洲在内的北边球温带国家（地区）都会出现周而复始的流感活动强度增加，这是包括流感在的呼吸道感染性疾病流行的一种自然规律。美国和中国的监测结果表明，目前流行的绝大部分流感病毒没有发生明显变异，与本季节使用的流感疫苗株匹配良好，并对神经氨酸酶抑制剂类药物（如达菲）敏感。美国流感疫情不会对中国产生影响，公众无需恐慌。（记者胡浩）
