Oral Herpes Survival Rate, Transmission, Etc?

1.) How long can the herpes virus live on surfaces? 2.) Can someone transmit oral herpes without an outbreak? What is the likelihood of transmission? What is the likelihood of transmission from sharing chapstick/drink/utensils without an outbreak? 3.) How common is asymptomatic shedding? 4.) How long after you shared something with someone would a blood test detect the infection or antibodies (knowing you have never had exposure to the virus)?
