Differences between the epidemic in May and October 2022

The epidemic situation in October is more severe than that in May. The strains of this round of epidemics are more insidious, spread faster, and are relatively less toxic. They can easily cause hidden transmission among the population and cause the spread of the epidemic. . Coupled with cooler weather, climate change is one of the important natural factors. Climate changes such as cold waves and low temperatures are generally detrimental to epidemic prevention and control. The virus is resistant to cold but not heat, and if the relative humidity is high, the virus will survive for a long time; if the relative humidity is low, the drier the virus will be, the shorter the virus will survive; low temperature will extend the survival time of the virus in the environment, making it easier for it to spread.
