Hi Marianne,

Reports of sick and dying birds have come in from central Ohio. There is little known about the disease currently, so the recommendations to take down and clean bird feeders include all of Ohio. Here is a fact sheet with more info -

The National Wildlife Health Center recommends taking down feeders for 7-10 days, and cleaning them before putting them back up. If you are seeing sick or dead birds in your area, you may decide to keep them down for longer. I'm sorry I don't have more specific recommendations than that, but we are working with a severe lack of knowledge. Hopefully we will get more information soon!
