Résumé
Mosquito is a vector of many infectious diseases,and it is recognized a leading killer of human in the world.After the Belt and Road Initiative launches,more are countries involved and the international communication and cooperation are sig-nificantly growing in China.Therefore,the risk of imported infectious diseases is increasing as well,some mosquito-borne dis-eases which have been well controlled or seldom seen in China,will be more risky to cause locally transmission from imported cases and become the threat to people's health in China.This paper reviews the risk of major imported mosquito borne-diseases to China,and discusses the control strategy as well,so as to provide the suggestion for entry-exit inspection and control of im-ported mosquito-borne diseases in China.
Résumé
Coronaviruses are a large family of viruses which include viruses that cause the common cold and severe acute respiratory syndrome (SARS) in humans and other diseases in animals. There are considerable genetic diversities within coronaviruses due to their wide rang hosts and their special gene replication and transcription mechanisms. During this process, gene recombinations often occur, resulting in novel subtype or coronavirus emerge constantly. Of note are SARS-like-CoVs and novel HCoV-EMC identified in 2012. This minireview summarized major advances of recently identified coronaviruses, focusing on the genome structures and interspecies jumping mechanism of coronavirus.
