Can a kiss with a girl that has herpes on the neck with no visible or oral legions cause herpes on the neck? And if so how long will it take symptoms

Herpes. 90% of those who get herpes do not get lesions, sores or symptoms. Blood testing for an acute exposure takes two routes. There is igm and igg antibody testing. The igm, if positive, is a sign of a new or acute infection. Igg antibodies represents a previous or 'older' infection. One cannot rely upon symptoms to tell them they have been exposed to a new herpes infection.
