Egypt has the herpes virus, too. Usually the very first flare up is the very worse and after that, they usually only exhibit milder flare ups (cold like symptoms) when stressed. At this stage, I wouldn't worry about it. My vet never tested Egypt, but was able to diagnose her based on an eye infection followed by a really bad URI she had when I first adopted her. It took a good month to get rid of it. She's had 1 or 2 mild flare ups since (no eye infection, just goopy eyes and lots of sneezing). It will be a year in June since I adopted her.
L-lysine works great when they are having flare ups or you can give it on a regular basis just to be safe, but unless the eye becomes red, inflammed or you can see the third eye lid out. Other than that, I would just wipe her eye as you have been doing and just wait it out...most likely it won't get any worse.
