Columbia/Boone County health officials report 153 county residents currently in isolation because of contact with a known COVID-19 case.

UPDATE 3 P.M.: Missouri set another record for new COVID-19 cases in a day, eclipsing the old mark set this week by more than 100.
The state Department of Health and Senior Services reported 553 new cases Thursday to reach 19,421. The state reported seven new deaths to reach 982.
The number set a new record, topping the previous mark of 434 set Tuesday. The department said Thursday's figures were pushed higher by a backlog of tests reported by Quest Diagnostics. The medical testing company reported its results for tests Sunday through Wednesday on Thursday.
Quest reported 160 positives from that period on Thursday, the department said.
Cases statewide have been on the rise as businesses reopen, people return to more normal activities and testing increases. Cases statewide have risen 9.5 percent over the past week, according to the state's online COVID-19 dashboard.
The average daily new cases over the last seven days is 359, the highest number of the entire pandemic.
The state reports testing more than 341,000 people for live coronavirus, with 5.5 percent of them testing positive.
The health department's director said this week many of those now testing positive are younger Missourians who are at lower risk of complications from COVID-19. Hospitalizations are at an all-time low, Dr. Randall Williams said Tuesday.
The states with the three largest populations -- California, Florida and Texas -- each set records for daily increases on Wednesday.
The state no longer publishes daily hospital reports from the Missouri Hospital Association in favor of weekly, regional reports. According to the most recent data for the central region of Missouri, hospital capacity was at 22 percent on Saturday and ICU capacity was at 39 percent in the region.
