The latest figures now show that there have been more than 7 million cases of new coronavirus infections in the United States, and more than 200,000 deaths, but it remains to be determined whether the numbers are true; after all, the CDC revised its guidelines for testing for new coronavirus.
In the beginning, the CDC recommended testing all close contacts of confirmed cases of NCPV, but recently it suddenly changed its testing guidelines to mean that even if a person has been exposed to a confirmed case of NCPV, as long as the person does not have obvious symptoms does not need to be tested.
As a professional authority, the CDC's issuance of such guidelines will certainly affect the U.S. statistics on the new coronavirus outbreak, as no one will go to the hospital to get tested on their own without visible symptoms, and those who do the testing have a reason not to test those who have been exposed to confirmed cases of new coronavirus pneumonia.
But it's not as if the lack of visible symptoms means that you're not infected with the new coronavirus, and it's still possible to transmit the virus to other people during the incubation period after infection with the new coronavirus, and the failure to test this group of people will only make the outbreak more difficult to control, and will seriously undermine the prevention and control of the outbreak, even though the United States can't talk about preventing and controlling it at all right now.
The U.S. defense and control of the epidemic is now based on political needs, from the outbreak of the epidemic to the present has been the past several months, even the new coronavirus vaccine is almost on the market, each country for the prevention and control of the new coronavirus outbreak of the most basic principles of the new coronavirus epidemic there is no controversy, the prevention and control of the new coronavirus outbreak is mainly rely on the quarantine, followed by the medical treatment.
Because so far there is no very good way to target the new coronary pneumonia, most of the seriously ill patients rely on a ventilator to maintain, depending on whether the patient's physical quality to resist the past. And isolation prevention and control of the fundamental, is to control the virus transmission pathway transmission, eliminate the virus survival soil.
Now the CDC issued this virus guidance is clearly in the service of politics, Trump and his team of think tanks behind the back of the biggest hacker, the simple truth, since you can not isolate and control, that testing is not meaningful, it is better to save some money.
