气候因素对病毒流行的影响

 综述了SARS病毒、登革热病毒、流感病毒、呼吸道合胞病毒流行与气候的关系，认为病毒产生于一定的自然条件和环境，特定的气候因素是病毒流行的推手，相同的气候更有利于病毒的流行。超出域值之外，气候因素则会限制甚至阻断病毒传播。探讨了不同气候因素的作用，可完善病毒性疾病的预警机制，有助于对可能产生的疫病暴发提前做好防治准备。

Influence of climatic factors on virus epidemic

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.
