Washington: The United States announced all air travelers entering the country will need a negative Covid-19 test before departure, as the country hit a record of nearly 4,500 deaths in a single day.
The policy takes effect on January 26 and expands an existing measure targeting Britain, where the strain known as B117 has been tied to a drastic spike in cases.
Ireland, which now has the world's highest per capita infection rate, also announced it was extending testing measures that previously applied only to travelers from the U.K and South Africa.
The United States remains the worst-affected country, with around 380,000 -- or a fifth -- of the world's almost two million dead, despite accounting for just four percent of the global population. In 24 hours, the U.S recorded more than 235,000 new cases and a record high of 4,470 deaths, according to the Johns Hopkins tally.
