Douglas County reported 2,877 cases of COVID-19 as of Tuesday, an increase of 38 cases since Monday.

George Diepenbrock, spokesperson for Lawrence-Douglas County Public Health, said some of the new cases reported Tuesday were due to an update in the state’s disease surveillance system that delayed some results from this weekend.

In Douglas County, 2,594 out of the 2,877 cases are inactive or beyond the infectious period, according to Lawrence-Douglas County Public Health, meaning 283 cases are active.

The county has averaged about 15 new cases per day over the last 14 days, according to a 14-day moving average graph updated weekdays by the health department. The current average of 15.14 new cases per day is down from a high of 46 cases per day in early September and up from a recent low of nine cases per day in early August.

Eight patients at Lawrence’s hospital had COVID-19 on Tuesday, one fewer than Monday. The virus has killed 18 county residents.
