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.

New Zealand's first instance of COVID-19 transmission in six months has been identified as the highly contagious delta variant.

"We are dealing with a delta variant," New Zealand Prime Minister Jacinda Ardern announced during a press conference in Wellington on Wednesday. "Our case has originated in Australia."

The case, which was detected in the community on Tuesday, prompted New Zealand to immediately impose a nationwide lockdown. More community cases have emerged since then, with the cluster growing to 10 by Wednesday afternoon, according to data from New Zealand's Ministry of Health.

Ardern said genomic sequencing has linked the initial case to an outbreak of the delta variant in neighboring Australia's New South Wales state.

"Now, the job we have is to work through how and when it got here," she said.

It's the first time that the island nation of 5 million people has confirmed the presence of the delta variant, which was initially identified in India last October. At least 148 countries around the globe have reported cases of the delta variant, according to the World Health Organization.

It's also the first time in more than a year that New Zealand has had a snap level four lockdown, the highest level of restrictions.

In total, the country has reported 2,936 confirmed cases of COVID-19 since the start of the pandemic, including 26 deaths, according to health ministry data.
