YANKTON, S.D. (WNAX) – Mayors of South Dakota’s 16 largest communities have signed a joint letter asking people to take actions to help slow the spread of COVID-19.

Yankton Mayor Nathan Johnson says they felt a unified message was necessary.

The Mayors are asking people to wear masks when appropriate, stay socially distanced and stay home if you feel sick.

Johnson says it has been the same message since the start of the pandemic.

Johnson says most cities don’t want to initiate any sort of public health mandate.

Johnson says the recent surge in positive cases shows that more active prevention measures are needed.
