Cold sores are contagious and spreads easily?
I've never had a cold sore in my life until today. Can you suddenly get herpes Type I kiss someone? You can also turn type I herpes herpes type II, oral sex?
Yes, cold sores are very contagious and spread very quickly. The kiss is the best way to convey a sores. Herpes simplex type I (commonly known as oral herpes) and herpes simplex virus are different, but are not very demanding. II simple, is not unusual to have oral herpes or genital herpes simplex I. The virus does not change type to another, however.
