Spikes in flu and respiratory illnesses are causing some major hospitals in East Tennessee to implement restrictions for visitors.

The University of Tennessee Medical Center and Covenant Health say anyone under the age of 12 and anyone showing signs of illness, such as cough, congestion and an upset stomach, that aren’t seeking medical care are not allowed to visit patients.

Officials are monitoring the situation and will update the visitation policy as soon as it is deemed safe to do so.

According to the Centers for Disease Control and Prevention, Tennessee ranked “very high” for the week ending on December 28th of reports of respiratory illness with fever. It was one of six states with the highest ranking.
