Sars is the most serious epidemic in human history. In nine months, SARS spread to all countries in the world. This epidemic not only threatens people's lives and health, but also has a great impact on public health and safety around the world. The spread speed is extremely fast, and it has spread to Hong Kong, Vietnam, Singapore and European and American countries in just a few months.
In order to control the epidemic quickly, China has launched a series of anti-epidemic policies. Students and workers are required to report their body temperature every day. If the temperature is too high, they need to go home to isolate and continue to report their temperature.
The difference between COVID-19 and SARS
The infectivity of SARS is weak at the initial stage of infection, and will gradually increase with the aggravation of the disease, accompanied by symptoms such as fever, cough and dyspnea. More obvious symptoms enable people to find SARS in time and better control the spread of the virus.
In the early days, the epidemic in COVID-19 was asymptomatic and spread rapidly. The rapid mutation in COVID-19 made it very difficult to completely solve it. Once someone does not cooperate with epidemic prevention measures, it is easy to cause the virus to spread again. So it went on and off for more than three years. Fortunately, the situation is much lighter now than before, but we still can't take it lightly and protect ourselves.
