Diseases caused by virus epidemic have become a risk factor affecting human health and there are different degrees of outbreaks at home and abroad almost every year. The outbreak of viral diseases is related to many factors, one of which is climate. Many studies have shown that under certain conditions, weather conditions such as temperature, precipitation, relative humidity, air pollutant concentration, and some extreme weather events are closely related to virus epidemic. The relationship between the epidemic of SARS virus, dengue virus, influenza virus, respiratory syncytial virus and climate is reviewed in this article. It is shown that virus is produced in certain natural conditions and environment, specific climatic factors are the driving force of virus epidemic, and similar climate is more conducive to virus epidemic. Beyond the domain value, climate factors will limit or even block the spread of virus. The effects of different climatic factors are discussed, which can improve the early warning mechanism of viral diseases and help prevent and contain possible outbreaks in advance.
