　H7N9 H7N9 lethal H5N1 risk well below the public need not panic unduly

Chinese scientists published online last June in the world famous medical journal the Lancet said in a research paper on h 7N 9 avian mortality risk is far lower than in patients with human infection with H5N1 avian influenza, but higher than for seasonal influenza and influenza a h 1N 1 influenza. Two research papers completed by China's Center for disease control and the University of Hong Kong scientists.

Among them, the person infected with a (h 7N 9) avian influenza virus clinical severity assessment paper, human infection with h-7N 9 hospitalized patients died of avian flu risk for 36%, clinical severity of less than about 60% 70% died in hospital case fatality rate, h 5N 1 at risk of bird flu. H 7N 9 there is a mild avian influenza virus infections and asymptomatic infections. Public h 7N 9 avian influenza do not need to panic unduly. Another article titled Chinese people infected with avian influenza virus h h 5N and 7N 9 comparison of epidemiologic features of 1: research papers based on laboratory confirmed cases of people, world was first reported by h h 5N and 7N 9 12 types of key comparison of the epidemiological characteristics of human cases of avian influenza virus.

Papers made, in city area, h 7N 9 and h 5N 1 cases male are obviously than female, but in rural area, h 7N 9 cases male is female of 1.6 times times, and h 5N 1 cases female is male of twice times; h 7N 9 cases half above for 60 age and the above of elderly, but h 5N 1 cases to young mainly; h 7N 9 and h 5N 1 virus of incubation period similar, averages respectively for 3.1 and 3.3 days; h 7N 9 hospital cases of death risk far below h 5N 1 cases ; City and rural area h 7N 9 cases of average close contact who number respectively is 21 and 18 people, are significantly below h 5N 1 cases of close contact who average number (city 90 people, rural 63 people); h 7N 9 cases onset to laboratory confirmed of average interval time than h 5N 1 cases shortened has 2.4 days, but in hospital treatment time obviously longer than h 5N 1 cases.

　　H7N9致死风险远低于H5N1 公众对H7N9无需过度恐慌

　　中国科学家去年6月在线发表于世界著名医学期刊《柳叶刀》上的研究论文称，H 7N 9禽流感患者死亡风险远低于人感染H5N1禽流感，但高于季节性流感和甲型H 1N 1流感。两篇研究论文由中国疾控中心和香港大学科学家合作完成。

　　其中，《人感染A(H 7N 9)禽流感病毒临床严重性评估》一文提出，人感染H 7N 9禽流感住院患者死亡风险为36%，临床严重性低于约60%病死率、70%住院死亡风险的H 5N 1禽流感。H 7N 9禽流感病毒存在一定的轻症感染和无症状感染。公众对H 7N 9禽流感无需过度恐慌。另一篇题为《中国人感染禽流感病毒H 7N 9和H 5N 1的流行病学特征比较：基于人群实验室确诊病例的研究》的论文，全球首次报道了H 7N 9和H 5N 1两种禽流感病毒人间病例关键流行病学特征的异同点。

　　论文提出，在城市地区，H 7N 9和H 5N 1病例男性均明显多于女性，但在农村地区，H 7N 9病例男性是女性的1.6倍，而H 5N 1病例女性是男性的2倍；H 7N 9病例一半以上为60岁及以上的老年人，但H 5N 1病例以青壮年为主；H 7N 9和H 5N 1病毒的潜伏期相似，平均值分别为3.1和3.3天；H 7N 9住院病例的死亡风险远低于H 5N 1病例；城市和农村地区H 7N 9病例的平均密切接触者人数分别是21和18人，均显著低于H 5N 1病例的密切接触者平均人数(城市90人，农村63人)；H 7N 9病例发病至实验室确诊的平均间隔时间比H 5N 1病例缩短了2.4天，但在医院治疗时间明显长于H 5N 1病例。
