流行性出血热(EHF)的传播途径,目前有接触、消化道、呼吸道、虫媒、垂直传播等几种学说,哪一种途径为主,尚无定论。东北部队从50年代后期即有流行性出血热病例发生,从60年代初就开始进行有关流行病学调查,注意研究其传播途径。从80年代开始,有针对性地进行了一些传播途径的动物实验研究工作。现将有关调查及实验研究结果报告如下。1 经破损皮肤接触传播1.1流行病学调查我所魏仰华等在1971、1982年两次EHF暴发的调查中,均观察到患者于病前1个月内都有不同程度的皮
Epidemic hemorrhagic fever (EHF) transmission, there are currently contacts, digestive tract, respiratory tract, insect media, vertical transmission and other several theories, which one approach is the main, there is no conclusion. From the late 1950s, the northeastern army took the case of epidemic hemorrhagic fever. From the early 1960s, epidemiological investigations began, paying attention to studying its route of transmission. Since the 1980s, some experimental research on animal transmission has been carried out in a targeted manner. The relevant investigation and experimental study results are reported below. A broken skin contact transmission 1.1 Epidemiological survey Wei Yang Hua, etc. In 1971, 1982 two EHF outbreak were observed in patients with disease within 1 month before the disease have varying degrees of skin
