The US is reopening its borders to Europe, the global epicenter of Covid-19

The United States has reopened its borders to vaccinated international travelers, ending a 20-month travel ban at the same moment Europe is battling a surge of Covid-19 cases that has pushed the continent back into the epicenter of the pandemic.Fully vaccinated travelers from 33 countries -- including the United Kingdom and much of Europe -- can now enter the US without needing to quarantine, provided they have proof of vaccination and a negative viral test. Families and friends separated since the start of the pandemic streamed into airports across major European cities on Monday morning, excited to see loved ones for the first time since former President Donald Trump imposed tough travel restrictions at the outset of the pandemic in an effort to control the virus.
