The CDC now recommends two additional options for how long quarantine should last for high risk exposures. Based on local availability of viral testing, for people without symptoms quarantine can end:
On day 10 without testing
On day 7 after receiving a negative test result
After stopping quarantine, people should:
Watch for symptoms until 14 days after exposure.
If they have symptoms, immediately self-isolate and contact their healthcare provider.
When you get well, get vaccinated.
Duration of isolation and precautions
For most persons with COVID-19 illness, isolation and precautions can generally be discontinued 10 days after symptom onset and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms.
For persons who never develop symptoms, isolation and other precautions can be discontinued 10 days after the date of their first positive RT-PCR test for SARS-CoV-2 RNA.
Role of PCR testing after discontinuation of isolation or precautions
For persons previously diagnosed with symptomatic COVID-19 who remain asymptomatic after recovery, retesting is not recommended within 3 months after the date of symptom onset for the initial COVID-19 infection.
