Patients in one region of Texas are experiencing extraordinarily long waits for hospital beds as COVID-19 continues to spread through the state.

Patients in southeast Texas, which includes Houston and the surrounding areas, are waiting in ambulances, hallways and more holding spaces for hospital beds to free up, Houston officials announced at a press briefing Tuesday.

Of the 678 patients holding in area emergency rooms with general admission orders, 265 of them have been infected with the virus, according the Southeast Texas Regional Advisory Council.

The ratio of patients who tested positive with COVID-19 is even worse for ICU admissions. Of the 112 patients in holding area emergency rooms who need an ICU bed, 75 have the virus, according to SETRAC.

Texas Gov. Greg Abbott has tested positive for COVID-19, his office announced.

The governor is fully vaccinated and has no symptoms, his office said, adding that he's been tested daily.

Abbott is receiving Regeneron's monoclonal antibody treatment, his office said.

"Everyone that the Governor has been in close contact with today has been notified," his office said.

Abbott has banned mask and vaccination mandates in Texas.

According to The Houston Chronicle, the governor gave a speech Monday night to a crowd of about 600 people where there was little social distancing or mask-wearing.

The U.S. could see as many as 32,800 hospitalizations per day by Sept. 13, according to the COVID-19 Forecast Hub at U Mass Amherst, which is used by the Centers for Disease Control and Prevention. The low end of the forecast is 9,000 per day.

Currently, more than 11,249 patients are hospitalized with COVID-19 each day in the U.S., up from a daily average of 8,300 last week.

These forecasts suggest Florida, Louisiana and Texas hospitalizations may improve in coming weeks while other states, like California and New York, may see more hospitalizations.

An Alabama doctor is seeing young, healthy patients die from COVID-19 amid the surge of the delta variant.

Dr. Jenna Carpenter, a pulmonary care physician at Marshall Medical South in Guntersville, Alabama, has lost three patients under the age of 40 in the past week from complications related to COVID-19, she told ABC Huntsville, Alabama, affiliate WAAY.

"The young man I lost this week was perfectly healthy," she said. "He wasn't overweight. He did not have any known medical issues and that was a tragedy."

The worst phone call the physicians have to make is to inform family members that their loved one has taken a turn for the worst, Carpenter added.

"In our heart we know this is going to be the last time these folks talk to their families," she said.

The state currently has more ICU patients than beds, and frontline workers are also getting sick from the highly contagious variant, WAAY reported.

"Last week we were down to 35 or 40 ICU beds. Now we are down at the single digits," Dr. Don Williamson, a former state health officer who is now the president and CEO of the Alabama Hospital Association, told the station. "It doesn’t matter if it is six or two, we could even be negative ICU beds."
