The CDC Just Made This Major Change to Its Guidelines

There are new CDC isolation rules to help protect people from being infected by those with COVID.

By now, we all know the coronavirus mainly spreads from person-to-person contact. So, if you've been near someone who has the coronavirus, you could be infected through their respiratory droplets when they cough, sneeze, or even just talk. That's why the Centers for Disease Control and Prevention (CDC) recommends that anyone who has COVID-19 self-isolate for a certain period of time—even if they test positive but don't have symptoms, as asymptomatic people can still spread the virus. But how long should those with COVID be self-isolating to make sure they don't infect friends, family, or even strangers? Well, this has been a topic of discussion throughout the pandemic, and the CDC just changed its self-isolation guidelines to reflect the latest research.

On July 22, the CDC updated its guidelines to indicate that most people with COVID-19 can end isolation 10 days after they first show symptoms. However, this is only as long as the person's symptoms have seemingly improved, and they have not had a fever for at least 24 consecutive hours without using fever-reducing medicine. Previously, the CDC had recommended that people who test positive isolate until they had two negative COVID tests, a difficult task amid testing shortages, The Washington Post notes.

The CDC also now instructs those without symptoms who have the virus to self-isolate for 10 days after their first positive coronavirus test.

Isolation guidelines are for those who test positive for COVID. The term "quarantine," on the other hand, is used for anyone who's been in contact with an infected person, but is not confirmed to have COVID. For those people, the CDC recommends a 14-day quarantine.

According to the CDC, their recommendation is based on the timeframe for which someone remains infectious and can spread the virus to other people. The infectious period declines after the onset of symptoms, and "patients with mild to moderate COVID-19" typically don't remain infectious 10 days after their first symptoms, the CDC says.

However, the agency does note that there can be exceptions, particularly among those with severe COVID and immunocompromised patients. "A limited number of persons with severe illness may produce replication-competent virus beyond 10 days that may warrant extending duration of isolation and precautions for up to 20 days after symptom onset," the report states.

But this doesn't mean complications, long-lasting symptoms, or virus detection cannot be found 10 days after symptom onset. In fact, the CDC notes that recovered COVID-19 patients can still "shed detectable SARS-CoV-2 RNA in upper respiratory specimens" up to three months after their illness started. However, the virus concentrations in shedded particles are lower—meaning "infectiousness is unlikely," the CDC says.

A CDC report from July 10 highlights the importance of self-isolation, estimating that 50 percent of coronavirus transmission occurs in the period of time when someone is pre-symptomatic. After all, it can take anywhere from two to 14 days for symptoms to develop after you've become infected. That's why the CDC recommends that you quarantine for 14 days if you have been exposed to someone who has COVID-19.
