If herpes is not oral (such as herpes gladiatorum on forehead from wrestling) can it be spread through saliva? additional, can it be spread any other way except contact with infected area?

Herpes simplex virus (HSV) is spread only by direct contact. Saliva is not a likely source of infection, except maybe if there is oral herpes with an active outbreak (cold sore, fever blister) -- even then, transmission is primarily by kissing or oral sex. Skin infection from athletic contact is called herpes gladiatorum. It's not transmissible by oral contact unless your mouth itself is infected.
