Coronavirus Updates: Delta variant accounts for 4 out of 5 cases

COVID-19 Live Updates, News and Information
NEW YORK (WABC) -- The Delta variant is spreading furiously among the unvaccinated, and it's now estimated to account for four out of every five cases of COVID-19.

"The Delta variant now represents 83% of sequenced cases," CDC Director Dr. Rochelle Walensky said. "Vaccines are widely available across the country, and this suffering and loss is simply and entirely preventable."

Across the country, the average number of patients admitted to hospitals each day is up to more than 55%.

Chicago Mayor Lori Lightfoot says she is considering reinstituting restrictions.

"If we allow the virus to continue to linger here in Chicago, we will likely have to re-enforce some of the restrictions that have come to infamously define much of 2020 and part of 2021," she said.

Meanwhile in Arizona, schools aren't allowed to require students or teachers to wear masks. The most populous county in the state is Maricopa, which has seen a 75% increase in COVID cases in just the last week.
