Both virus types are highly contagious and most commonly passed from person to person by touching the blisters or sores of the symptomatic person. The risk of catching or transmitting these viruses is likely if you or your partner has blisters or sores, but Herpes can still be transmitted if you or your partner does not have symptoms. Herpes can be transferred in non-sexual ways such as touching or kissing.
Once you have been infected with Herpes, it can be reactivated every so often causing new episodes or outbreaks. Recurrent symptoms are almost always on visible skin.
