VERMILLION, S.D.(WNAX)- Two weeks ago the Vermillion School District required face masks for most of their students as Covid-19 infection numbers rose.

Now, Superintendent Damon Alvey says they are extending and expanding the mandate.

Alvey says their infection numbers had been pretty stable.

Alvey says both staff and students have been infected.

The state Department of Health website reports Clay County now with over six hundred seventy active infections.
