South Dakota set new highs in the daily number of people infected with COVID-19 on Wednesday, as well as reported new infections.
The South Dakota Department of Health reported 1,270 new infections, as well as 412 hospitalizations, an increase of 17 in the previous 24 hours. Nine additional people died, bringing the statewide total to 384.
The number of active infections increased by 754, totaling 11,933.
State epidemiologist Josh Clayton said Wednesday that there are 28 people in South Dakota who have possibly been reinfected with the disease 90 days after their first infection, raising questions about how long antibodies can fight future infections.
Minnehaha County residents accounted for 284 new infections. A number of those appear to have been in prisoners and staff at the South Dakota Penitentiary. As of Tuesday, the Department of Corrections had reported 597 positive results in prisoners and staff there. Clayton said that number had grown to 710.
Lincoln County had 98. Brown County accounted for 31 new cases while Codington County had 36 new infections.
Six of the nine people who died were over the age of 80, while one was aged 70-79, one aged 60-69 and one aged 50-59, the Department of Health said. The deaths were reported in Brookings, Campbell, Lake, Oglala Lakota, and Minnehaha counties, as well as two residents each in Codington and Walworth counties.
