DALLAS (CBSDFW.COM/AP) — Texas health officials reported more than 3,900 new cases of COVID-19 Saturday, as the virus continued to put pressure on hospital systems around the state.

State health authorities reported more than 8,500 Texans hospitalized with COVID-19 Saturday, roughly in line with the Friday count. Texas added 3,954 confirmed cases of the virus and 102 fatalities Saturday, according to the Texas Department of State Health Services.

Texas has had more than 1 million confirmed COVID-19 cases and 21,309 fatalities. The actual number of cases is believed to be far higher because many people haven’t been tested and some who get the disease don’t show symptoms.

Over the last seven days, more than one in 10 coronavirus tests in Texas have come back positive, according to data from Johns Hopkins University.

In the El Paso and San Antonio areas local leaders have issued partial curfews through Monday morning in an effort to limit the spread of the virus during the Thanksgiving holiday weekend.

Dallas County on Saturday reported 982 new cases and four deaths, which were from late Wednesday afternoon. The county is expected to release numbers from Thursday, Friday and Saturday on Sunday, Nov. 29.

“We will be able to tell to what extent we saw a spike from the Thanksgiving weekend beginning one to two weeks after it is over. This is due to the latency period for the virus and the onset of symptoms,” Dallas County Judge Clay Jenkins said Saturday.

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 symptoms and be fatal. The vast majority of people recover.
