EVANSVILLE — One day after adding just seven new COVID-19 cases, Vanderburgh County reported a daily record of 63 cases on Thursday, according to the Indiana State Department of Health's statewide dashboard.

The stunning one-day turnaround likely reflected the ebb and flow and speed of test processing involving multiple laboratories. Wednesday's seven new cases came against 205 newly administered tests, while Thursday's 63 cases flowed from 592 new tests.

The new data makes a total of 2,876 COVID-19 cases in Vanderburgh County since the first case emerged on March 19, according to the ISDH. The state agency's dashboard indicated the county's day-to-day increase was 62 cases, but the total it offered was 63 cases higher than Wednesday's total.

The ISDH dashboard now offers four separate figures for positivity rates — the percentage of people tested who come up positive for COVID-19. In Vanderburgh County, the "unique individuals" positivity rate was 7.6% cumulative and 6.8% over the seven days covering Aug. 28 to Sept. 3.

Both of those figures are up slightly over Wednesday's numbers.

An "all tests" positivity rate was 4.4% cumulatively and 2.5% over the same seven-day period.

School-age cases are on the rise

There is solid evidence in Thursday's numbers that local students are acquiring COVID-19 — although Evansville Vanderburgh School Corporation, the area's largest school system, will not publicly acknowledge cases.

The school-age demographic of children age 0-19 continued its recent steady climb upward to 13.6% of positive cases in Vanderburgh County. On May 21 —when Vanderburgh County had just 228 COVID-19 cases in all — just 3% involved individuals 19 or younger.

The statewide figure increased slightly Thursday to 12.4%.

A total of 38,046 individuals in Vanderburgh County have tested for COVID-19 since March 9, with 49,517 total tests administered.

The number of COVID-19 cases that remain active in Vanderburgh County is no longer available. The Vanderburgh County Health Department's dashboard had been providing that number — but the local agency stopped reporting COVID-19 data in July, ceding control of all local data to ISDH. The state agency has taken over local contact tracing and case investigation but doesn't issue a number of local active cases. 

The ISDH updates its online dashboard of COVID-19 data daily, including deaths, as it tracks the effects of the coronavirus pandemic.
