Respiratory infection?

I'm worried Templeton might have a respiratory infection, he has been making a sound like someone with a stuffy nose. He isn't breathing heavy and is eating fine, this just started and besides the noise he seems fine. I've been sick with a nasty flu but wash my hands before feeding the boys and haven't been handling them.

Should I take him to the vet? I'm concerned about a car ride with me being sick (as well as concerned I wouldn't make the distance very well either, but obviously will if I need to). Is there something I can do otherwise or in the meantime?
