The Minnesota Department of Health (MDH) has launched a new online survey for COVID-19 case investigation in an effort to more efficiently track coronavirus cases. With the new approach, when someone tests positive for COVID-19, MDH will send them a text message inviting them to participate in a survey.

“By responding to the text with an email address, people who test positive for COVID-19 can complete the online survey without having to wait for a call from a public health worker.”

MDH’s Kris Ehresmann says case investigation is the first step when someone tests positive to determine close contacts of someone who tested positive for COVID-19.
