It wasn't an impediment to travel.
But it was a consideration, and, for many, an unwanted hassle and expense.
But as of Sunday, June 12, the U.S. is ending the requirement that international travelers take a test and test negative for Covid-19 before coming to the United States.
That means that people traveling from the U.S. to Ireland this summer will not be required to take a test before being able to return to the U.S.
The ending of the requirement was announced by the Biden administration and is based on a CDC determination.
The decision will be broadly welcomed by airlines and the travel industry in the U.S., in Ireland, and elsewhere.
Earlier this year Ireland dropped the requirement that people arriving in the country be Covid tested pre-arrival.
The test had to be taken within one day of travel and a negative result was needed in order to fly. The test also had to be paid for by the individual traveler.
Travelers will still have to show that they have been vaccinated against Covid-19.
