Children ages 2 through 17 years (minors) who are noncitizen nonimmigrants do not have to quarantine after arrival in the United States; however, the attestation requires that they get a COVID-19 viral test 3-5 days after arrival. If a child, like any other traveler, tests positive for COVID-19 or develops COVID-19 symptoms, they should isolate for a full 5 calendar days. They should also properly wear a well-fitting mask any time they must be around others during their full 5 day isolation period and for an additional 5 days after ending isolation.
