A concerning variant is about to become dominant in the US, experts say, and how Americans act could help fuel or curb a surge
CNN
Experts are worried some Americans are letting up too early -- at a critical time when looming dangers are threatening to wipe out the progress the US has made in its battle against Covid-19.
At least a dozen state leaders have eased Covid-19 restrictions this month, often citing improving Covid-19 trends and growing vaccination numbers. At the same time, air travel is hitting pandemic-era records and the first spring break crowds have begun descending on Florida and other sunny regions while cases of a dangerous variant are on the rise. The Transportation Security Administration said it screened more than 1.3 million people at airports Sunday -- meaning about 5.2 million travelers flew since Thursday. That's the highest number of people that have traveled by air during any other four-day period of the pandemic.More Related News
