今年1月10日以来,我国南方部分省份遭受几十年不遇的低温雨雪冰冻灾害。时值春运,冰冻灾害不仅使电力系统遭到破坏,交通运输陷于瘫痪,更使几十万回家过年的旅客滞留在公路、车站和机场。而寒冷的气温以及人口的大量集聚,极有可能导致发生诸如冻伤、心脑血管病急性发作、急性呼吸道和肠道传染病等各种公共卫生问题。 Since January 10 this year, some provinces in the south of China have suffered from freezing and freezing snow and snow disasters for decades. During the Spring Festival, the frozen disasters not only damaged the power system, but also transported traffic. As a result, hundreds of thousands of people who went home for the New Year were stranded on roads, stations and airports. The cold temperatures and the large concentration of the population are likely to lead to various public health problems such as frostbite, acute attack of cardiovascular and cerebrovascular diseases, and acute respiratory and intestinal infectious diseases.
