The recent outbreak of respiratory illness in Wuhan, China is caused by a novel coronavirus, named 2019-nCoV, which is genetically close to a bat-derived coronavirus. 2019-nCoV is categorized as beta genus coronavirus, same as the two other strains - severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). Antiviral drugs commonly used in clinical practice, including neuraminidase inhibitors (oseltamivir, paramivir, zanamivir, etc.), ganciclovir, acyclovir and ribavirin, are invalid for 2019-nCoV and not recommended. Drugs are possibly effective for 2019-nCoV include: remdesivir, lopinavir / ritonavir, lopinavir / ritonavir combined with interferon-β, convalescent plasma, and monoclonal antibodies. But the efficacy and safety of these drugs for 2019-nCoV pneumonia patients need to be assessed by further clinical trials.
2019新型冠状病毒(2019-nCoV)是武汉不明原因肺炎的致病原。2019-nCoV在遗传学上与一种蝙蝠来源的新型冠状病毒比较接近，与SARS-CoV、MERS-CoV同为β属冠状病毒。目前临床上常用的抗病毒药物，包括神经氨酸酶抑制剂（奥司他韦、帕拉米韦、扎那米韦等）、更昔洛韦、阿昔洛韦、利巴韦林等药物对2019-nCoV均无效，不建议临床应用。目前研究证实可能有效的药物包括：瑞德西韦、洛匹那韦/利托那韦、洛匹那韦/利托那韦联合干扰素-β、恢复期血浆、单克隆抗体。但这些药物在2019-nCoV肺炎患者中的疗效和安全性有待进一步临床实验证实。.
