The Delta variant now accounts for more than half of the new coronavirus cases in the United States —52%. Almost all of the new cases — 99.7% —are among people who have not been vaccinated... The effort comes as cases are rising in 26 states. Hospitalization rates are up in 17 states — 27% in Florida, almost exclusively among the unvaccinated. The far corners of Utah are hit hard, too. "We're seeing people that are extremely sick with it," said Dr. Greg Gardner, chief of emergency medicine at Mountain West Hospital in Tooele, Utah. "A lot sicker than what they were the majority of the time in the winter time."
