SIOUX FALLS, S.D. (AP) — An employee at the Minnehaha Juvenile Detention Center has tested positive for COVID-19, the facility's director said Saturday.

Detention center director Jamie Gravett told The Associated Press that the Sioux Falls facility was informed of the positive test Friday “and immediately began informing guardians, our partners, and contractors while caring for our youth and keeping them safe." Staff and juveniles are being monitored for symptoms and have their temperatures taken twice each day, she said.

The center in March put restrictions on visitors and began using “enhanced sanitation procedures,” Gravett said. The facility currently has 29 juveniles and 50 staff members.

Of the 132 new cases reported in the state Saturday, 119 were in Minnehaha County, the location of the large outbreak at a Sioux Falls pork processing plant. The Smithfield Foods facility is one of the largest known clusters of COVID-19 cases in the U.S., with 634 workers and 143 of their close contacts testing positive as of Friday.

South Dakota's total number of COVID-19 cases jumped from 1,411 to 1,542.

With cases on the rise, the National Guard said it has selected locations for two 100-bed temporary hospitals to treat COVID-19 patients, one in Sioux Falls and one in Rapid City.
