A coronavirus variant first spotted in India is poised to become the dominant one in the United States, where infectious disease modelers say it could cause a "resurgence" of Covid-19 later this year.

And it may already account for 1 in every 5 infections nationwide, experts say.

The Delta variant, as it's now called, has swept across the UK, all but replacing the Alpha variant first identified there late last year.
