Russ, if the eyes do NOT seem to be getting better within three to four days of antibiotic eye drops, which only works for bacterial conjunctivitis, then it may be the viral strain, which is much more difficult to treat. Therefore, it's imperative to contact the eye doctor if the problem worsens or remains the same after three to four days of treatment.
If it is the viral strain, then steroidal eye drops are the only treatment available. And, this particular strain takes several weeks to successfully treat.
More often than not, conjunctivitis is usually contracted from another person, and often it's someone that you've come in contact with that may seem to have just a bad cold. If you shake their hand, then inadvertently rub your eyes, wallah - you WILL get it.
Over the years I've managed to avoid many of these disease transmittal problems by merely carrying antibacterial wipes with my at all times, both in the van and a small pack in my accessory bag. After glad handing a lot of audience members, the first thing I do before packing up my gear is wipe my hands with the wipes. Even this is not an iron-clad guarantee that you are safe, but as my loving spouse of a half-century says "It's better than nothing."
Good luck,
Gary
