I'm familiar with Lupus, I just didn't realize that echinacea causes complications, argh.

And, yeah, both staff and the public go to the library and share germs while they're still contagious - it's very frustrating. Yesterday The Kid really wanted to go to school and to her friend's club meeting, but even if her cold was mild, on Day One I didn't want her coughing and spewing on others, no way. It was bad enough she coughed on me all day! I'm taking echinacea now as a precaution.
