肠道病毒包括那些?其流行特点如何? 肠道病毒(En terov i ru s)是1957年命名的一批能在人肠道繁殖的病毒。按病毒的定位和排泄原则来分类也不完全正确,因为这批病毒中的不少病毒尚可自人的其他部位(呼吸道、脊液、其他器官等)分离出来。现知肠道病毒有60多个型,包括三群病毒,第一群按疾病命名,脊髓灰质炎病毒(Polio virus)1～3型;第二群按分离地点命名,柯萨奇病毒(Cox sackie Viru s),A组1～24型,B组1～6型;第三群:孤儿病毒(ECHO Virus),1～34型。肠道病毒的主要流行病学特征:①感染以经口(粪一口)为主,也可经飞沫由咽
What are their enteric viruses? What are their epidemiological features? Envivoviruses are a group of viruses that colonize the human gut in 1957. According to the principle of virus localization and excretion is not entirely correct classification, because many of these viruses are still from other parts of the human body (respiratory tract, spinal fluid, other organs, etc.) isolated. It is now known that there are more than 60 types of enterovirus, including three groups of viruses. The first group is named after the disease, polio virus type 1 to type 3, the second group is named after the isolation site, the Coxsackie virus sackie Viru s), group A to type 24, group B to type 1 to 6; group 3: orchovirus (ECHO Virus), type 1 to 34. The main epidemiological features of enterovirus: ① infection by oral (fecal one), but also by the droplets from the pharynx
