Since the outbreak of COVID-19 in Wuhan, China, at the end of 2019, it has demonstrated China's ability to identify unknown pathogens. At present, reports showed that the main transmission routes are respiratory droplets and indirect contact, other vertical transmission routes have yet to be confirmed. This review discusses the possible transmission routes of 2019-novel coronavirus (2019-nCoV), based on currently research, the main transmission routes are respiratory droplets and indirect contact, fecal-oral might bepossible, while aerosol, tear (conjunctival) and mother-to-fetus still have yet to be confirmed, providing a reference basis for 2019-nCoV prevention and control and public protection.
自2019年底，中国武汉暴发新型冠状病毒（2019-nCoV）肺炎以来，展现了我国对未知病原鉴定的能力。目前，报道的传播途径主要通过呼吸道飞沫和间接接触传播为主，其他传播途径还有待证实。本文讨论了2019-nCoV的可能传播途径，现有研究证实呼吸道的飞沫传播和接触传播是主要途径，粪口途径传播可能性比较大，气溶胶传播、泪液传播和母婴传播途径仍有待证实，为2019-nCoV的防控及公众防护提供参考依据。.
