The president highlighted the benefits of wearing masks, despite his earlier claims that people who wore them were making a political statement.
WASHINGTON – The U.S. Centers for Disease Control and Prevention has updated its rules on how long other people in the U.S. will be isolated. After testing positive for COVID-19.
In the rules published online, the firm states that having data on the infection indicates that maximum adults with mild to moderate coVID-19 cases remain infectious “no more than 10 days” after the date their symptoms began.
Instead of a 14-day quarantine window, the CDC now recommends 10 days after the start and 24 hours after the onset of fever.
“For others with COVID-19 disease at most, isolation and precautions may be interrupted 10 days after the onset of symptoms and the solution of fever for at least 24 hours, without the use of fever medications and with an improvement in other symptoms”, firm states.
But the CDC noted that a “limited number of other people with a serious illness” may continue to transmit the virus beyond 10 days and wants to isolate itself for a longer period of time, up to 20 days after the onset of symptoms.
Since the new coronavirus first gave the impression six months ago, researchers have been quick to gain a better understanding of the virus and its transmission. People’s idea is to be the maximum contagious at the beginning of their infection.

“One of the main problems with general rules regarding contagion and transmission of this coronavirus is the marked differences in how it behaves in different individuals. That’s why everyone needs to wear a mask and keep a physical distance of at least six feet,” Harvard Health explains on its website.

The CDC also added that studies indicate that other inflamed people with a similar but distinct human coronavirus would likely be vulnerable to the disease approximately 90 days after the onset of the disease.
“For others recovered from SARS-CoV-2 infection, a positive PCR within 90 days of the onset of the disease is more likely to be a persistent excretion of viral RNA than reinfection,” the CDC wrote.
Regarding the length of time a person might be infectious, medical experts have issued recommendations in accordance with the new CDC guidelines.
Julian Tang, a virologist at the University of Leicester in the UK and the National University of Singapore, told The Washington Post that he had informed clinical groups that patients could be released from isolation after 10 days.
“You probably wouldn’t reach absolute risk 0,” Tang said, “but studies have shown that viral loss stops after 10 days,” he said.
A research paper published in March in the journal Nature found that antibodies were actually able to neutralize the virus approximately five days into the initial onset of infection. No live virus was detected by the eighth or ninth day, according to researchers.
While these findings are promising, the CDC added that “even for pathogens for which many years of knowledge are available, it would probably not be imaginable to make recommendations to ensure that one hundred percent of others who excrete a replicating virus remain isolated.”
As more data on the new coronavirus is obtained, the CDC said they would monitor updates and provide more data that would “justify reconsidering those recommendations.”
