What happens if I get COVID-19 while traveling?
Depending on your destination, it could result in an unexpected change in plans, such as being required to stay isolated in a hotel.
It's why the US Centers for Disease Control and Prevention recommends that you have backup plans ready if you're traveling abroad. You might have to stay longer than planned if you test positive.
In some places, you won't be able to board flights until you test negative. In others, you might also be required to stay in a quarantine facility.
Since results from a PCR test can remain positive for weeks after an infection, those who have had COVID-19 might have to get documentation from a doctor or health authorities saying they've recovered. Some travel only requires an antigen test.
