Maryland doctor explains why CDC quarantine guidelines changed – CBS Baltimore

BALTIMORE (WJZ) – The US Centers for Disease Control and Prevention announced Monday that it will shorten the recommended quarantine period for people who test positive for COVID-19 and have no symptoms.

“The change is driven by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, typically in the 1-2 days before the onset of symptoms and 2-3 days afterwards,” the CDC said.

Recommendations for people who no longer develop symptoms vary depending on their vaccination status.

According to the CDC, anyone who tests positive for COVID-19 should isolate at home for five days, regardless of whether they have been vaccinated.

If people don’t have symptoms after those five days have passed, the CDC says they can be quarantined. However, the agency said it should continue to wear masks for five days to minimize any asymptomatic spread.

Dr. Miriam Alexander, director of employee health and wellness at LifeBridge Health, said the CDC’s guidelines are based on the risk of transmission someone has.

“All of the scientific evidence that CDC has reviewed seems to suggest that your maximum infectious period, the maximum time you can transmit (COVID-19), has passed five days,” said Dr. Dr. Alexander said.

The CDC also updated its recommendations for how long people should quarantine after they’ve been exposed to COVID-19.

If you come into contact with a person who is positive and has not been vaccinated or is not fully vaccinated, the agency recommends isolating for five days, followed by another five days of wearing a mask around other people.

The same recommendation applies to people who have not received a booster shot but 6 months after their second vaccination, or two months after their Johnson & Johnson shot.

People who have received a second dose of Pfizer or Moderna within the past six months and who have received the Johnson & Johnson vaccine within the past two months do not need to be post-exposure isolation.

The same goes for people who have received additional injections.

Instead, the CDC recommends wearing masks for 10 days after they’re exposed.

Regardless of vaccination status, anyone who has been in contact with someone with COVID-19 should get tested around the following Thursday.

Doctors say the best way to protect yourself and your loved ones is to get vaccinated and get a booster shot if you haven’t already.

“The reason you hide and vaccinate yourself is to maximize the chance that others make bad decisions that won’t negatively affect you,” says Alexander. “You can never control your fellow man, but you can control yourself.” Maryland doctor explains why CDC quarantine guidelines changed – CBS Baltimore
