(KNZA)--Jackson County Jail inmates are being tested for COVID-19, following a prison-bound inmate testing positive earlier this month.

According to a release from Jackson County Sheriff Tim Morse, the Kansas Department of Health and Environment has completed the initial round of testing, with six additional inmates testing positive for the virus. However, Morse said all tested inmates were asymptomatic.

A second round of testing, conducted December 17, resulted in no new positive cases.

Morse said a third round of testing was planned for Wednesday.

According to Morse, his office’s medical staff continues “to be diligent in monitoring the health of the inmates.”
