康相关的diffusion. Today, health departments around the world are making great efforts to try to do this again. But at present, the number of people infected with the new coronavirus is still growing. How deadly? Mortality or far lower than SARS mortality is one of the most important factors that determine the lethality of an outbreak. The New York Times said that early signs indicate that the mortality rate of the new coronavirus is much lower than that of the other two coronaviruses: MERS (Middle East Respiratory Syndrome) with a mortality rate of one-third, and SARS with a mortality rate of about one-tenth (Atypical pneumonia). All three viruses seem to be attached to proteins on the surface of lung cells,。

收益,例But MERS and SARS are more destructive to lung tissue. As of January 31, fewer than one fortieth of the people who had been confirmed to be infected with the new coronavirus, and many of the deaths were elderly people with the original disease. Dr. Allison McGeer, an infectious disease expert at Mount Sinai Hospital in Toronto, has participated in the fight against SARS. He told the New York Times that there are still many uncertainties about the nature and mechanism of the new coronavirus. He also said that the low mortality rate does not necessarily mean that the risk of pathogens is also low. Like seasonal flu。

如心The mortality rate is less than one in a thousand, but in the United States, about 200,000 people are still hospitalized for flu each year, and about 35,000 of them die. What is the incubation period? About 2 to 14 days officials of the US Centers for Disease Control estimate that the incubation period of the new coronavirus is 2 to 14 days. It is unclear whether carriers of the virus can spread the virus before the onset of symptoms, or whether patients with severe symptoms are more likely to spread the virus. This worries me because it means that the infected person may escape detection. Vanderbilt University (Vanderbilt University) infectious disease expert Mark Denison (M。

理,eDr. arkDenison) told the New York Times. The New York Times stated that the time it takes for symptoms to appear after infection is critical to prevention and control. This period of time is called the incubation period, allowing health officials to isolate or observe people who may have been exposed to the virus. However, if the incubation period is too long or too short, these measures may be difficult to implement. If the incubation period is only two or three days, such as influenza, the infected person may spread the virus before the onset of the disease. At this time, it is almost impossible for medical staff to identify and isolate the infected person. The incubation period of SARS virus is about 5 days, and the patient may not take the virus until four or five days after the onset of symptoms。

社会和Spread out. Dr. McGill told the New York Times accordingly that this gave the epidemic prevention staff time to stop the virus and effectively control the epidemic. How difficult is the epidemic control? The difficulty of transportation hub "New York Times" pointed out that the reason why the new crown virus spread quickly is because it started in a transportation hub city-Wuhan, which makes the epidemic control more difficult. Wuhan has a registered population of nearly 10 million and a floating population of about 5 million. On average, 3,500 passengers take direct flights from Wuhan to other countries every day. The New York Times stated that these cities with direct flights to Wuhan were the first to report the discovery of new coronavirus pneumonia outside China。

身体收Cases. Wuhan is also an important transportation hub in China. Through high-speed rail and domestic airlines, Wuhan is connected to the whole country. It is reported that in October and November last year, nearly 2 million people flew from Wuhan to all parts of China. When the SARS outbreak broke out in 2003, China's transportation was far from being so developed. The New York Times said that in terms of total volume, China now has four times as many passengers as trains and planes during the SARS outbreak. After the outbreak, China took unprecedented measures to impose travel restrictions on tens of millions of people living in Wuhan and nearby cities. However, the deputy secretary of the Wuhan Municipal Party Committee and mayor Zhou Xianwang issued a press release on January 26。

益.这项研jIt was admitted at the meeting that because of the influence of the Spring Festival and the epidemic, there are currently more than 5 million people leaving Wuhan. Lawrence O. Gostin, a professor of law at Georgetown University and director of the World Health Organization ’s National and Global Health Law Cooperation Center, said it (the virus) will always come out. How effective are the response measures? Helping the world WHO officials praised China's positive response to coronavirus. My impression of the powerful measures China has taken to deal with the epidemic。
