Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation for the public. People with COVID-19 should isolate for 5 days and if they are asymptomatic or their symptoms are resolving (without fever for 24 hours), follow that by 5 days of wearing a mask when around others to minimize the risk of infecting people they encounter. The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after.
The Centers for Disease Control and Prevention on Thursday loosened many of its recommendations for battling the coronavirus, a strategic shift that puts more of the onus on individuals, rather than on schools, businesses and other institutions, to limit viral spread.
No longer do schools and other institutions need to screen apparently healthy students and employees as a matter of course. The CDC is putting less emphasis on social distancing — and the new guidance has dropped the “six foot” standard. The quarantine rule for unvaccinated people is gone. The agency’s focus now is on highly vulnerable populations and how to protect them — not on the vast majority of people who at this point have some immunity against the virus and are unlikely to become severely ill.
The new recommendations signal that the Biden administration and its medical advisers have decided that the lower fatality rate from covid-19 in a heavily vaccinated population permits a less demanding set of guidelines.
Additionally, CDC is updating the recommended quarantine period for anyone in the general public who is exposed to COVID-19. For people who are unvaccinated or are more than six months out from their second mRNA dose (or more than 2 months after the J&J vaccine) and not yet boosted, CDC now recommends quarantine for 5 days followed by strict mask use for an additional 5 days. Alternatively, if a 5-day quarantine is not feasible, it is imperative that an exposed person wear a well-fitting mask at all times when around others for 10 days after exposure. Individuals who have received their booster shot do not need to quarantine following an exposure, but should wear a mask for 10 days after the exposure. For all those exposed, best practice would also include a test for SARS-CoV-2 at day 5 after exposure. If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19.
In addition to basic health and hygiene practices, like handwashing, CDC recommends some prevention actions at all COVID-19 Community Levels, which include:
1. Staying Up to Date with COVID-19 Vaccines
Improving Ventilation
2. Getting Tested for COVID-19 If Needed
3. Following Recommendations for What to do If You Have Been Exposed
4. Staying Home If You Have Suspected or Confirmed COVID-19
5. Seeking Treatment If You Have COVID-19 and Are at High Risk of Getting Very Sick
6. Avoiding Contact with People Who Have Suspected or Confirmed COVID-19
