CDC shortens recommended isolation and quarantine time for Covid-19

The CDC has also shortened the recommended time frame for quarantining people exposed to the virus to a similar five days if vaccinated. Fully vaccinated and stimulated people may not need to self-quarantine at all, the CDC said.

“Based on what we currently know about COVID-19 and the Omicron variant, the CDC is shortening the recommended isolation time from 10 days for people with COVID-19 to five days, if asymptomatic, followed by five days of wearing a mask in the presence of other people, “the CDC said in a statement.

People whose symptoms improve can also leave their homes after five days as long as their symptoms improve, the CDC said. People who have a fever should stay home until the fever goes away, the CDC added.

“The change is driven by science showing that the majority of SARS-CoV-2 transmission occurs early in the illness, typically within 1-2 days before symptoms appear and 2-3 days after. Therefore, people who have positive tests should be isolated for five days and, if they are asymptomatic at that time, they can leave the isolation if they can continue to mask themselves for five days to minimize the risk. infect others. ”

Quarantine refers to the time that people stay away from others if they are exposed to an illness but have not yet tested positive or are not showing symptoms.

The CDC also changed these recommendations. “For people who are unvaccinated or more than six months away from their second dose of mRNA (or more than two months after the J&J vaccine) and not yet boosted, the CDC now recommends a five-day quarantine followed by strict use. of the mask for an additional five days, ”he said.

A break for the boosters

“Alternatively, if a five-day quarantine is not possible, it is imperative that an exposed person wear a properly fitted mask at all times when around others for 10 days after exposure,” added the CDC.

People who are vaccinated and stimulated are generally released from quarantine, the CDC said.

“People who have received their booster injection do not need to self-quarantine after exposure, but must wear a mask for 10 days after exposure,” he said.

“For all those exposed, best practice would also include testing for SARS-CoV-2 on the fifth day after exposure. If symptoms develop, individuals should immediately self-quarantine until tested. negative confirms that the symptoms are not attributable to COVID-19. “

Dr Anthony Fauci said the changes were aimed, in part, at keeping the company running smoothly.

“With the sheer volume of new cases that we have and plan to continue with Omicron, one of the things we want to be careful of is that we don’t have that many people,” Fauci told CNN’s Jim Acosta. . .

“We want to get people back to work, especially essential jobs, so that society can run smoothly,” said Fauci, director of the National Institute of Allergy and Infectious Diseases.

Boosters reduce the risk

The boosters significantly reduce the risk of a person being infected and spreading the virus to someone else, the CDC said.

“Data from South Africa and the UK show that the vaccine’s efficacy against infection for two doses of an mRNA vaccine is approximately 35%. A booster dose of the COVID-19 vaccine restores the effectiveness of the vaccine against the infection at 75%, “he said.

“The Omicron variant is spreading rapidly and has the potential to impact all facets of our society,” CDC director Dr. Rochelle Walensky said in a statement.

“The CDC’s updated recommendations for isolation and quarantine balance what we know about the spread of the virus and the protection provided by vaccination and booster doses. These updates ensure that people can continue with their daily lives in a safe way. Prevention is our best option: get vaccinated, get a booster, wear a mask in indoor public places in areas of high and high community transmission, and get tested before you assemble. ”

Anyone who can get the vaccine should get one, the CDC said.

“Vaccination against COVID-19 decreases the risk of serious illness, hospitalization and death from COVID-19. The CDC strongly encourages vaccination against COVID-19 for all ages 5 and up and booster shots for all ages 16 and up. Vaccination is the best way to protect yourself and reduce the impact of COVID-19 on our communities.

Last week, the CDC updated its guidelines for healthcare workers with Covid-19 who have no symptoms or have mild symptoms, saying they can return to work after seven days if they are negative for infection at this stage.

Previously, people exposed to Covid-19 but who had not tested positive were advised to quarantine for 14 days, and people who tested positive for Covid-19 were required to self-isolate for 10 full days.
