More than 5.81 million cases of pneumonia in COVID-19, 美国!

有超过 5.81 million cases of pneumonia in COVID-19, 美国. The US CDC said that the close contacts have no symptoms and can be questioned without testing.

The US media reported on the 25th local time that the CDC recently revised its guidance on novel coronavirus testing, and people who have been exposed to the virus environment but have no symptoms will no longer be recommended for testing.

According to CNN, the CDC official website revised the relevant content on the 24 th and said: “If you contact the infected person at close range (6 脚) for at least 15 分钟, but there is no symptom after that, then you will not have to be tested unless you belong to a vulnerable group, or your medical insurance provider, state or local officials recommend testing.”

“Not everyone has to test.” Official website said, “But if you really accepted the test, you should be isolated at home for 14 天, waiting for the test results, and follow the advice of medical experts.” The CDC also mentioned that health officials may ask asymptomatic “healthy people” to be tested according to the specific epidemic situation in various places.

然而, the CDC’s previous guidance indicated that anyone who has been exposed to the virus in a short period of time or may be exposed to the environment where the virus exists is recommended to be tested. Previous suggestions also wrote: “Considering the risk of infection of asymptomatic infected people and those who have not yet developed symptoms, people who have been exposed to confirmed patients must be confirmed and tested immediately.” 而且, the CDC currently predicts that 40% of the infected people may be asymptomatic, 和 50% of the virus transmission may have occurred before the infected people showed symptoms.

CNN pointed out that the CDC did not give an explanation for this modification, which caused many doctors to have doubts. “I worry that these instructions mean that even people who have had very close contact with infected people don’t have to be tested now.” Leana Wen, a professor of public health at George Washington University, said, “It is strange why these guidelines should be revised … is it to cover up the lack of testing in the United States?”
