Summary
What is already known about this topic?
After exposure to COVID-19, a 14-day quarantine period can prevent further spread but might be challenging to maintain.
What is added by this report?
Among persons exposed to COVID-19 in the household who were asymptomatic and had negative laboratory test results through 7 days after symptom onset in the index patient, 19% experienced symptoms or received positive test results in the following week.
What are the implications for public health practice?
A shorter quarantine after household exposure to COVID-19 might be easier to adhere to but poses some risk for onward transmission. Persons released from quarantine before 14 days should continue to avoid close contact and wear masks when around others until 14 days after their last exposure.
