Health officials reported more than 900 new coronavirus cases in Tarrant and Dallas counties on Sunday.
In Dallas County, a record 570 COVID-19 cases were reported. Tarrant County reported 393.
Both counties each reported one new death.
A Fort Worth man in his 50s with underlying health conditions is the latest coronavirus casualty in Tarrant County. In Dallas County, health officials reported the death of an Irving man in his 80s. He did not have underlying health conditions, officials said.
Since tracking began in March, Dallas County has tallied 20,165 confirmed cases of the coronavirus. The death toll is 352.
Tarrant County has confirmed 11,476 coronavirus cases since tracking began in March. There have been 225 deaths.
Both counties have also seen a spike in coronavirus hospitalizations, prompting Dallas County Judge Clay Jenkins to push for Gov. Greg Abbott to require Texans to wear masks when they leave home.
Businesses started reopening in May after Abbott lifted the statewide stay-at-home order. But, the governor rolled back some of his reopening measures.
On Friday, he ordered the closure of bars. Restaurants are required to reduce indoor dining to 50% by Monday.
The governor and several other Texas leaders met with Vice President Mike Pence and other White House officials during a briefing on the coronavirus response on Sunday.
During a news conference, the governor encouraged people to wear masks and to stay home unless they absolutely must go out.
Abbott made the decision to roll back the reopening as cases and hospitalizations have continued to surge across the state for several weeks, surpassing new highs almost every day.
Sunday was the first day the state has not seen a new record number of hospitalizations, dropping down below 5,500 after 16 straight days of record highs, reaching 5,523 hospitalized COVID-19 patients Saturday.
The number of COVID-19 patients in North Texas hospitals rose slightly on Sunday, from 1,248 Saturday to 1,261 people. The rise set a new record for the region as well, which has about 444 ICU beds available, state officials report.
The region around Houston, however, has a much smaller number of available ICU beds, about 169, with 1,642 COVID-19 patients currently hospitalized, the highest number of any region in the state.
Over the month of June, Tarrant County's hospitals have seen an influx of COVID-19 patients as the number of beds occupied by those with the disease have more than doubled to about 11% of total hospital patients and about 7% of total beds.
Dallas County officials said the same trend had occurred there, with the number of Dallas County residents with COVID-19 being treated in a hospital having doubled in June.
