　　WHO: There is no "magic bullet" for the new crown

　　But the epidemic can still be controlled

　　The Director-General of the World Health Organization Tan Desai said on the 3rd local time that the new crown epidemic is a "once in a century" health crisis. Within three months, the number of global cases has increased by more than five times, and the number of deaths has more than tripled.

　　He said that the new crown epidemic has touched all aspects of society, economy, and politics outside the health field, and may further affect the next few decades. But it can still be controlled. If the government does a good job of testing and strengthening health requirements, the impact of the epidemic can be minimized.

　　Tan Desai emphasized that although many vaccines are currently under development, there is currently no "magic bullet" for new coronary pneumonia, and there may never be one. At present, stopping the outbreak still depends on the basic measures of public health and disease control.

　　He said that a mask challenge will be launched this week to encourage people around the world to wear masks safely. He also called for keeping physical distance from others, avoiding crowded places, covering when coughing, and washing hands frequently to protect themselves and others.

　　The White House begins to mandate testing

　　According to real-time statistics from Johns Hopkins University in the United States, there are currently more than 4.71 million confirmed cases in the United States and more than 155,000 deaths.

　　American chief infectious disease expert Fauci said on the 3rd that more attention should be paid to indoor air recirculation. If people stay in indoor spaces with poor air circulation and "any degree of atomization", they may face greater risks. He emphasized that wearing a mask indoors is just as important as wearing a mask when in contact with unknown strangers outdoors.

　　In addition, Fauci also said that the new crown epidemic is still spreading in many states in the southern United States, and the positive rate of testing in Tennessee, Kentucky, Ohio, and Minnesota is also rising. He said that these states should consider suspending or canceling the "restart the economy" plan and adopting restrictive measures again. He emphasized that the number of new crown cases must be kept at a low level before the flu season this fall.

　　On the other hand, a White House official stated that starting from August 3, local time, staff in the President’s Executive Office will be forced to conduct random tests for the novel coronavirus. This type of testing has been going on for several months, but it was done voluntarily before. Earlier, Trump's national security adviser O'Brien tested positive for the new crown.

　　As of the 3rd, the number of newly diagnosed people in Germany in the past seven days has increased to 4839, a significant rebound from the same period last month. German President Steinmeier stated that all German citizens bear the responsibility of avoiding the country’s “closure of the city” again. He warned that if social life ceases again, it will have a much greater impact on people than earlier.
