Coronavirus Updates: US could see 4,000 deaths per day by October

NEW YORK (WABC) -- Some experts say the U.S. is on track to see 4,000 deaths per day by October, fears that are prompting new vaccine mandates across the country.

It comes as cases climb in 49 states and the highly contagious Delta variant threatens to overwhelm hospitals.

According to the CDC, every county in Arkansas and Louisiana has high levels of community transmission. In Florida, it's all but one county.

A hospital near Miami is taking "dire steps" to accommodate the number of new unvaccinated patients, including converting a hospital auditorium for more bed space and allowing only vaccinated visitors.
