Delta Wave Goes Coast-to-Coast in U.S., Showing Variant’s Force

The U.S. Covid-19 wave that started in low-vaccination states in the Ozarks and Deep South has now engulfed the country, with cases and hospitalizations at their highest since February.

Thirty-eight states have transmission levels considered high by the Centers for Disease Control and Prevention, meaning they’re posting at least 100 cases per 100,000 residents or have positivity rates of at least 10%. The other 12 states and the nation’s capital have transmission rates that are considered substantial, the second-worst category.
