COVID-19 cases are once again rising across the United States, and health experts believe a new variant, called XFG or ‘stratus,’ may be to blame. The increase is happening earlier than expected, just before schools reopen, raising fears of more spread in classrooms, Axios reported.

The variant was first detected in January in Southeast Asia. The World Health Organization had classified it as a “variant under monitoring” by June, due to its global spread. XFG was given its cloud-themed nickname "Stratus" by evolutionary biologist T. Ryan Gregory.

Here is the list of states with the highest COVID test positivity.

New Mexico (12%)

Nevada (11.3%)

Arizona (11.3%)

It has been observed that the US faces two distinct waves of COVID, one in the winter and another in the summer, as per USA Today. New variants, peaks in travel and decreasing immunity from prior infection and vaccination can lead to the surge, experts note.
