‘Today’s numbers are the highest number of new positive cases reported on record, breaking the record set yesterday,” said Dallas County Judge Clay Jenkins. “Remember, we are doing more testing and so that must be factored in. Of more concern is the increase we’ve seen over the last three days in hospital census for COVID-19 and sustained high ER visits for COVID-19 like symptoms.”

Currently, the North Texas 19-county area has the highest number of hospitalized COVID-l9 patients on record at 724 and likewise, Dallas County has its highest number on record at 373, Judge Jenkins explained.

“As we said several weeks ago, these are the numbers we’re looking at to most accurately predict a second surge and doctors are looking at these numbers closely.”

He said It’s more important than ever that people avoid large crowds, maintain six food distancing, wear a cloth face covering when on public transportation, around people in businesses or at other gatherings, and use good hygiene.

“It’s up to all of us to #FlattenTheCurve and the best way to do that is to #StayHomeSaveLives,” he said.
