The Kansas Department of Health and Environment has issued a warning to people who attended a conference at the Miracle Temple Church of God in Christ in Kansas City, Kansas, that they may have been exposed to the coronavirus.

According to reports, multiple people, including one death that may be connected to the event, attended the Kansas East Jurisdiction’s 2020 Ministers and Workers Conference from March 16-22 have become ill and tested positive for COVID-19, the department said in a news release Tuesday.

The church is located at 2106 Quindaro Boulevard.

“This event has been identified as a place of exposure for multiple people in Kansas who have since become ill and tested positive for COVID-19,” the release said.

Symptoms for COVID-19 appear up to 14 days after exposure and include fever, cough, and shortness of breath. Other rarer symptoms that may develop include malaise, sore throat and diarrhea.

The department warned people who attended the event that if they develop any of these symptoms, but are not sick enough to seek medical care, they must stay home for at least seven days after symptoms started or for 72 hours after the fever is gone, which ever is longer.

“If you attended this event and develop symptoms consistent with COVID-19 between 2 and 14 days later, please call your local health department as they will conduct a confidential investigation to prevent further transmission of COVID-19,” the release said.
