keep your system strong with vita C, lysine, and Colloidal Silver if you're so inclined. personally if you're that freaked out, work on curing yourself and then test yourself with the western blot test. your immune system will improve and hopefully the chances of you spreading it will at least diminish. and an anti-bacterial gel wouldn't likely work because it's viral. I would go with either a) spraying the region with Colloidal Silver , b) rubbing the skin with coconut oil (anti-bacterial, anti-viral, anti-fungal) or b) rubbing mixture of coconut oil and bht on skin (bht errods lipid envelope of virus.
I highly recommend reading all of Johnny Apple Bomb and Caliman's posts in this forum.
