The Coronavirus family has large members,wide host range and high variability,and is an important source of emerging infectious diseases in recent years.Most wild birds have the ability to fly and often migrate in clusters.As the natural host of avian influenza viruses and coronaviruses,co-infection is common,resulting in the wide spread of the virus,and seriously threatening social and public health security.By reviewing the research progress in the classification,host range and detection methods of coronaviruses,this paper comprehensively analyzes the current prevalence of coronaviruses in wild birds,and discusses the main methods and technologies for the diagnosis of coronaviruses in wild birds,as well as the challenges and future development trends.
