Dallas County officials plan to open a temporary mobile hospital and ask for medical help from the Texas National Guard to deal with the anticipated increase in serious coronavirus cases. County Judge Clay Jenkins held a press conference Thursday afternoon in which he said he needs help from the federal government. Jenkins said he's asking for 400 more test kits a day, since the two drive-thru testing sites have run out of test kits and shut down early for the past three days. Each site can perform only 250 tests a day.
