Western Sizzlin in Ooltewah closing Sunday night.

An employee confirmed the closure to Channel 3.

A sign on the door explains that since the diagnosis was announced, "patronage has since declined to unstainable business operations at this location."

The restaurant also thanked their "loyal customers" and apologized to the Ooltewah community.

Here is what the sign says in full:

To those loyal customers we have proudly served over the past 7 plus years we thank you for your patronage and regret not being able to continue to serve you. To the Ooltewah community we apologize that you may have been exposed to the hepatitis A virus while dining here from March 10-20, 2019 and for any panic, concerns and disruptions. We have always maintained a clean and food safe affordable local family owned and operated family restaurant for the community which can be backed up by our always maintaining Health Department Inspection Scores in the 90's. The Hepatitis A virus outbreak in our region is partial to no one and can be caught by anyone anywhere. We encourage everyone that ventures out in public places to obtain the free vaccine from the local Health Department. We also encourage everyone to do their homework on the virus. The (CDC) Centers for Disease Control website offers great information. Fortunately if you get it or have ever had it knowingly or unknowingly you will not get it again. Unfortunately, as we had had an employee that was diagnosed with the virus, our customer patronage has since declined to unstainable business operations at this location.
