Climate Change and its Impact on Some Viral Poultry Diseases

Climate change and its impact on some viral poultry diseases Abstract Climate changes is long term naturally or artificial shifts in temperatures and weather patterns. The planet is experiencing a swift rise in temperatures, largely due to the growing levels of carbon dioxide and other gases in the atmosphere, which are mainly produced by the burning of fossil fuels. Consequently, such changes may have impacted on the prevalence of epidemic viral diseases of poultry. Climate changes: temperature, humidity, and other weather-related phenomena affect viruses but they are also part of a complex of environmental and social factors. In addition, climate changes may include farm managements and wild life migration. Vector- and waterborne viral diseases. There is also the possibility of climate-related effects on the emergence of infectious diseases. Among the significant climate changes are the melting of Arctic ice and the occurrence of extreme weather events, which are strongly associated with the transfer of many infectious viral diseases. The most important viral diseases may cause loses in poultry farms are Newcastle, Gumboro, Chicken anemia virus, Infectious bronchitis and pox virus. Therefore, many investigators all over the world have been challenged for studying the impact of climatic changes on the prevalence, incidence, epidemiology and virulence of different viral diseases on poultry. The content of the current review article will be helpful in controlling of poultry viral diseases.
