DALLAS (CBSDFW.COM/AP) — Texas hit a new record high for COVID-19 hospitalizations Sunday, as a surge of the virus continued to strain state medical resources following holiday travel and gatherings.

State health officials reported 12,563 COVID-19 patients in Texas hospitals, an increase of more than 240 from Saturday. It was the sixth time in seven days that the state reported record breaking hospitalizations.

Intensive care units in several parts of the state were full or nearly full Sunday, according to the Texas Department of State Health Services.

The department reported 14,535 new confirmed cases of COVID-19 Sunday, 1,510 more probable cases and 50 fatalities. The actual number of cases is believed to be far higher because many people haven’t been tested and some who get sick don’t show symptoms.

In Dallas County, health officials reported a two-day total of 3,851 new cases and 10 deaths, for a total of 178,174 cases and 1,661 deaths. In Tarrant County, 4,367 cases and 13 deaths were added from Friday and Saturday, totaling to 157,732 cases and 1,525 deaths.

Over the last seven days, nearly one in five coronavirus tests in Texas has come back positive, according to data from Johns Hopkins University.

For most people, the coronavirus causes mild or moderate symptoms that clear up within weeks. But for others, especially older adults and people with existing health problems, the virus can cause severe illness and be fatal.
