City locals were voicing their concerns about not knowing as much information about the incident as they’d like.

“I’m very nervous because we’re away from the city and so we thought we were safe,” said Angela Chudy. “Stay home. Definitely stay home.”

Health officials are urging the community to practice prevention techniques and take advice for best practices during this pandemic.

“This outbreak a signal to anyone in the county who is not taking this pandemic seriously and is resisting complying with public health orders and guidelines that the threat of COVID-19 is very real,” Gustafson said. “Staying at home, minimizing non-essential contact with others, maintaining social distancing from even people we know and with whom we have regular contact, and consistently practicing good hygiene is our best hope of making forward the other side of this pandemic.”

In a written statement, officials also said there is a suspected case in Mentone. It’s unclear if it is connected to this incident.
