On January 26, 2021, the Centers for Disease Control and Prevention (CDC) declared that all international travelers wishing to board a flight to the US must have proof of a negative COVID-19 test taken at least three days before boarding.
Until recently, travelers had to get tested at a testing site in the country where they were located and wait for the results. Now travelers have another option — testing themselves. Home tests for COVID-19 can be a good option for those visiting countries where finding a testing facility that can turn around results within one to three days may be more difficult, a concern addressed on the CDC website.
