Progress of Influenza Viruses and Inhibitors


Yuchen Xiao, Jianping Yong, Shaoji Lu, Canzhong Lu* and Ruiwen Huang   Pages 1 - 23 ( 23 )


Influenza is an acute respiratory disease caused by influenza viruses. It has the characteristics of fast transmission and strong infectivity, and it does great harm to human health and survival. It is estimated that the seasonal influenza epidemics every year will cause about one billion cases of infections and hundreds of thousands of deaths worldwide, while influenza A virus is the leading cause of infection and death. Currently, the main drugs used in clinics to treat influenza viruses are neuraminidase inhibitors, and these drugs have shown excellent efficacy in treating influenza viruses. However, various mutant strains have developed resistance to these effective drugs in clinics (such as the subtype mutant strains of H274Y in H1N1 or H5N1 and E119V in H3N2 have developed resistance to Oseltamivir). Influenza viruses mutate frequently, and new viral strains are constantly discovered, and the pandemics will break out at any time. Therefore, it is urgent to develop efficient and broad-spectrum drugs to prevent and treat the influenza pandemic caused by the emerging new subtypes. This review focuses on describing the pandemic history, the structure, function and prevention methods of influenza viruses and the progress of the development of anti-influenza drugs, to provide the reference for prevention and treatment of influenza viruses and development of influenza virus inhibitors.
