And how long should she avoid contact with others? Trying to figure out how long people must quarantine for.
The decision to discontinue home isolation should be made in the context of local circumstances. Options now include both 1) a time-since-illness-onset and time-since-recovery (non-test-based) strategy, and 2) a test-based strategy.
Time-since-illness-onset and time-since-recovery strategy (non-test-based strategy)*
Persons with COVID-19 who have symptoms and were directed to care for themselves at home may discontinue home isolation under the following conditions:
At least 3 days (72 hours) have passed since recovery defined as resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (e.g., cough, shortness of breath); and,
At least 7 days have passed since symptoms first appeared.
----------
Test-based strategy (simplified from initial protocol) Previous recommendations for a test-based strategy remain applicable; however, a test-based strategy is contingent on the availability of ample testing supplies and laboratory capacity as well as convenient access to testing. For jurisdictions that choose to use a test-based strategy, the recommended protocol has been simplified so that only one swab is needed at every sampling.
Persons who have COVID-19 who have symptoms and were directed to care for themselves at home may discontinue home isolation under the following conditions:
Resolution of fever without the use of fever-reducing medications and
Improvement in respiratory symptoms (e.g., cough, shortness of breath) and
Negative results of an FDA Emergency Use Authorized molecular assay for COVID-19 from at least two consecutive nasopharyngeal swab specimens collected ≥24 hours apart** (total of two negative specimens). See Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens from Persons Under Investigation (PUIs) for 2019 Novel Coronavirus (2019-nCoV)for specimen collection guidance.
Individuals with laboratory-confirmed COVID-19 who have not had any symptoms may discontinue home isolation when at least 7 days have passed since the date of their first positive COVID-19 diagnostic test and have had no subsequent illness.
Footnote
*This recommendation will prevent most, but may not prevent all instances of secondary spread. The risk of transmission after recovery, is likely very substantially less than that during illness.
**All test results should be final before isolation is ended. Testing guidance is based upon limited information and is subject to change as more information becomes available.
