The Latest Situation of The COVID-19 Epidemic


As of September 23, 2020, there have been more than 31.68 million confirmed cases of COVID-19 worldwide, 23.29 million cured cases, 970 thousand deaths, and 7.41 million confirmed cases. On the 21st local time, World Health Organization Director-General Tan Desai said that the fastest way to end the COVID-19 and accelerate the recovery of the global economy is to ensure that all countries have people who can get the COVID-19 vaccine; Sumia, WHO Chief Scientist Swaminathan said that China's new crown vaccine research and development project is very active, and some vaccines have been proven effective in current clinical trials.


According to the Capitol Hill website, according to the latest statistics from Johns Hopkins University, the number of deaths from COVID-19 in the United States exceeded 200,000 on the 22nd local time. Near the Washington Monument on the National Mall in Washington, American flags were planted to mourn the dead. US President Trump responded at the White House and said that I think this is a shame. If we do not properly deal with the epidemic, 2.5 million people will die. This is a terrible thing.


On December 31, 2019, the World Health Organization China Office received a report of unexplained pneumonia in Wuhan. Since the first case of infection was confirmed in Japan on January 16 to March 10, cases of new coronary pneumonia have been confirmed in various countries. On March 11, Tedros announced that the COVID-19 has constituted a "global pandemic."


On March 15, 2020, a total of more than 76,000 cases of new coronary pneumonia were confirmed outside of China, and more than 2,700 deaths. Many countries declared a state of emergency. In addition, various epidemic prevention measures have been taken: travel restrictions and isolation measures have been adopted; epidemic prevention knowledge has been strengthened; and the whole society has been mobilized to respond. As countries control the epidemic, the epidemic in most countries has gradually been effectively controlled. However, there is a high probability that a second wave of outbreaks will occur.


At present, there is no uniform standard for the definition of the second wave of epidemics in the world, and the World Health Organization has no clear guidelines. WHO spokesperson Christian Lindmeier wrote in a reply to Deutsche Welle’s email: “This term (only) refers to a new outbreak that occurred after the initial outbreak has slowed. This also applies to the 'third wave'. ."


The virus likes a cold environment. This is one of the reasons why there have been multiple outbreaks of COVID-19 in cold slaughterhouses. Generally speaking, the spread of the virus slows down when it is hot. Therefore, in the warm season, the number of people infected with the virus is relatively small. In addition, if it is cold outside, people will spend more time indoors, and there will be less indoor air circulation than outdoors. This means that virus-laden aerosols (tiny air droplets) are more likely to spread.


Next, what should I do? Zhang Wenhong predicts that, in principle, this round of epidemic will continue for a long time. In the eyes of infectious diseases experts, "80% of people are asymptomatic, which is very scary." A virus with such a strong spread will always exist. The practice of Western countries is to wait for the vaccine to protect the vulnerable after the vaccine is released. The fatality rate will come down and drop to the level of conventional flu, that is, the overall mortality rate is less than 0.5%.


However, Zhang Wenhong estimates that this point of time will not be reached within one year, "because the vaccine is ready, it will take time to build a supply chain and distribute goods..." Moreover, the vaccine developed in the United States requires a cold chain and requires very high activity. China The inactivated vaccines developed are okay, but they all take some time to achieve. Therefore, "for the expectations of this world, a one-year plan should be the lowest limit."


The global COVID-19 infection is accelerating, and some countries may "secondarily close the city"


To prevent and control the epidemic,


Still can't be careless!
