Ómicron in the United States: the CDC’s clarification after the reduction to five days of isolation for those infected with Covid

WASHINGTON – He first reduced the lockdown from ten to five days last week. Now, after the wave of criticism, the Center for Disease Control and Prevention (CDC for its acronym in English) ratified its decision and ruled out rapid tests as a mandatory measure for infected people without symptoms, as updated by the official website of the institution.

“If you have access to a quick test [de antígenos], and if you want to do a test on day five, and if your symptoms are gone and you feel fine, go ahead. Probably, you shouldn’t visit your grandmother, you shouldn’t get on a plane and you still have to be very careful when you’re with other people ”, said Rochelle Walensky, director of the CDC.

For its part, the White House defended the measures calling them “measures based on science, not on communication plans.” In yesterday’s statement, the CDC explained that to make this decision they made a review of 113 studies from 17 countries that conclude that the highest probability of infection occurs “2-3 days before and 8 days after the onset of symptoms”.

The center has faced pressure over the past week from outside medical experts to include mandatory testing at the end of the shortened isolation period.

According to Our World Data from the University of Oxford, America is the third country with the highest number of cases after Great Britain and France. However, since the end of last year the mortality rate has been maintained.

The doctor Anthony Fauci, the White House’s chief infectious disease adviser, said “the likelihood of transmissibility is considerably lower.” in the second half of the 10-day period after a positive result.

Walensky added that “this decision really, from an isolation point of view, had a lot to do with the fact that we would not change our guidance based on the result of that quick test”.

Although the Food and Drug Administration (FDA) approved rapid tests since last year, this test is not considered a substitute for PCR tests. They argue that “20 out of 100 positive results can be false positives”.

On the other hand, the change in the measures has also been influenced by several companies seeking to open since last year. Delta Airlines sent a letter in mid-December requesting the reduction of quarantine days, arguing that the omicron variant has 25 to 50% lower fatality than the rest of the variants. This was joined by several companies.
