H7N9禽流感病毒是2013年3月起在我国上海、安徽等省份相继发现的新型禽流感病毒亚型。H7N9在禽类中属于低致病性的传染病,禽类感染后没有明显临床症状,不易发现,但H7N9感染人体后起病较急,严重者导致重症肺炎、呼吸衰竭甚至多器官功能障碍,最后导致死亡。与H5N1等能感染人的高致病性禽流感(HPAI)不同,H7N9具有“传人不传禽”的隐蔽性,首先在感染H7N9的人体中发现,后来才从家禽中检测到,而不是循着野生动物-家禽-人类的传统传播和发现途径。近来卫生部及各地区疾控中心运用各种手段对疑似患者及早发现、对确诊患者及时治疗,以期降低其对人类带来的危害和致死率。目前对H7N9的研究成为传染病学领域的热点。
The H7N9 bird flu virus is a new type of avian influenza virus that has been found in Shanghai, Anhui and other provinces since March 2013 in our country. H7N9 is a low-pathogenic infectious disease in poultry. There is no obvious clinical symptom after the infection in poultry, but it is not easy to find out. However, H7N9 causes severe pneumonia, respiratory failure and even multiple organ dysfunction after it infects the human body. death. Unlike HPAI, which can infect humans, such as H5N1, H7N9 has the potential to be “invisible to humans,” first detected in humans infected with H7N9 and later detected in poultry Not following the traditional route of wildlife - poultry - human transmission and discovery. Recently, the Ministry of Health and regional centers for disease control use various means to detect suspected patients early and timely treatment of patients diagnosed with the aim of reducing their harm to humans and lethality. At present, the research on H7N9 has become a hot spot in the field of infectious diseases.
