The U.S. Centers for Disease Control and Prevention has listed about 80 destinations worldwide at Level Four and raised Curacao’s island to Level Four. In November, the United States lifted restrictions at its land borders with Canada and Mexico for fully vaccinated foreign nationals, ending historic curbs on non-essential travelers put in place in March 2020 to address the COVID-19 pandemic.
After the first Omicron cases were reported, Canada withdrew its advisory last October, citing the success of vaccination campaigns.
In March, Canada saw an increase in the number of people hospitalized with COVID-19. They broke their one-day record for the highest number of people hospitalized this month.
On Friday, officials said that new daily cases had increased by 65% in the previous week, threatening healthcare systems.
CDC recommends all Americans be vaccinated before traveling to Level 3 destinations.
According to Reuters, the number of COVID-19 hospitalizations in the United States has reached a record high. The tally on Monday showed that there are now 132,646 cases, which is more than the 132,051 set in January last year.
