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.

U.S. Surgeon General Vivek Murthy announced at Wednesday's White House briefing, "Having reviewed the most current data, it is now our clinical judgment that the time to lay out a plan for COVID-19 boosters is now."

Murthy said protection against mild disease has decreased, likely a combination of waning vaccine protection over time and the strength of the delta variant, and that the administration is "concerned" that protection could continue to erode.

"Even though this new data affirms that vaccine protection remains high against the worst outcomes of COVID, we are concerned that this pattern of decline we're seeing will continue in the months ahead, which could lead to reduced protection against severe disease, hospitalization and death," Murthy said.

"That is why, today, we are announcing our plan to stay ahead of this virus by being prepared to offer COVID-19 booster shots to fully vaccinated adults 18 years and older," Murthy said. "They would be eligible for their booster shot eight months after receiving their second dose of the Pfizer or Modern mRNA vaccines."

The boosters are set to begin Sept. 20, but Murthy emphasized that this is pending FDA authorization and also reiterated that does not yet apply to J&J recipients.
