Sunday, Dallas County Judge Clay Jenkins said the record number on Saturday reflected a technical glitch that caused a surge of positive tests which should have been reported days earlier.
"That was 400 additional tests that should have been reported over the four or five days before then," Jenkins said.
Jenkins said the county discovered the problem after noticing a discrepancy between the number of tests performed at community-based testing sites and the numbers reported.
"We inquired on that. We found out these tests were not being accurately sent to us from the state system due to a glitch and that’s what we got yesterday," Jenkins said. "Unfortunately, what we don’t know is if there are any other labs that are stuck in that glitch and how that glitch is occurring at this state."
The numbers reported on Sunday were more consistent with the numbers Dallas County saw for four days prior to Saturday.
"Yesterday is probably an anomaly," Jenkins said. "Today is probably a more accurate number that we’re below 1,000 now."
The cases reported Sunday lowered the seven-day average in Dallas County to 792 new cases per day, down from 1,085 one week ago, but up from 413 on June 25.
Dallas County has 46,813 cases of the coronavirus and 605 confirmed deaths.
