Understanding inter-species transmission of influenza viruses is an important research topic. Scientists try to identify and evaluate the functional factors determining the host range of influenza viruses by generating the recombinant viruses through reverse genetics in laboratories, which reveals the viruses' molecular mechanisms of infection and transmission in different species. Therefore, the reverse genetic method is a very important tool for further understanding the biology of influenza viruses and will provide the insight for the prevention and treatment of infections and transmission. However, these recombinant influenza viruses generated in laboratories will become the potential threat to the public health and the environment. In this paper, we discussed the biological safety issues of recombinant influenza viruses and suggested we should set up protocols for risk management on research activities related to recombinant highly pathogenic influenza viruses.
