JEFFERSON CITY, Mo. — A three-day backlog of tests was reported Thursday by Missouri officials, resulting in the highest single-day increase of COVID-19 cases and tests in the state.
The Missouri Department of Health and Senior Services reported a total of 19,421 cases, an increase of 553 cases.
Despite the increase in total cases, the state's positivity rate decreased from 5.77% on Wednesday to 5.68% Thursday due to a record increase in new tests. The state reported 341,648 PCR tests Thursday, a single-day increase of 14,624.
Of the 553 new cases reported Thursday, 160 were from a three-day backlog from Quest Diagnostics. The backlog delayed the reporting of both negative and positive tests from the lab, a total of more than 13,000.
Dr. Randal Williams, the director of the Department of Health and Senior Services said the rolling seven-day average positivity rate in the state is about 4%.
Of the new cases reported Thursday, 95 came from southwest Missouri, where an outbreak at a food processing plant led to an increase in testing and cases over the weekend. Kansas City accounted for 105 of the new cases and St. Louis County reported 88 new cases.
Another 96 of the cases came from Sullivan County, which had previously reported 12 COVID-19 cases.
Dr. Williams said the CDC lead investigator arrived in Joplin on Thursday to look into the outbreak in southwest Missouri, and the Missouri National Guard would be in the area this weekend to help with community testing. Dr. Williams said it is the first time a CDC investigator has been called into the state to do an epidemiological COVID-19 study.
Hospitalization numbers in the state increased Thursday to a total of 600 COVID-19 patients across the state. The data is delayed 72 hours, and Thursday's update represents the hospital census from June 22.
In the St. Louis area, all the numbers tracked by the St. Louis Metropolitan Pandemic Task Force saw a single-day and seven-day average decrease Thursday.
The task force reported a total of 216 COVID-19 patients in area hospitals, the lowest number the task force has reported since it began tracking data and a single-day decrease of 31.
