Experts say that the CDC test requirements for British travelers are like “blocking mosquitoes with a chain fence”



Starting from Monday in the UK, passengers must undergo a negative Covid-19 test within three days of boarding and flying to the United States.

The statement said: “Today, President Trump is taking further measures to protect the health of the American people.”

This is the concern about variants of the coronavirus

But according to researchers from the CDC Covid-19 Response Team, tests conducted three days before the flight may not work well-reducing the risk of virus transmission by 5% to 9%.

Dr. Paul Offit, an infectious disease expert at the University of Pennsylvania, said the new testing requirements are “like putting up a chain fence to prevent mosquitoes.”
The CDC’s order acknowledges that “testing does not eliminate all risks”, but when combined with other measures (such as self-monitoring of symptoms, masks and distance), “it can make travel safer”.

Covid-19 tests usually miss the most recent infection, so someone can test negative and actually get infected because they did not release enough virus to be detected.

Researchers think there may be hundreds of people in the U.S. with the new British coronavirus strain

Dr. Peter Hotez, an infectious disease expert at Baylor College of Medicine, said: “The test 72 hours before the flight will be missed by many.” It may already be in the United States.

On the other hand, according to the November report of CDC scientists, the test of departure date may be more effective, reducing the risk of transmission by 37% to 61%. The report is based on mathematical modeling and has not been peer reviewed.

Health officials have been eager to limit the spread of the British variant, which seems to spread more easily than other coronavirus strains.

The CDC did not respond to a request for comment on this matter.
