Herpes infection seen on the palate of a 45 year old woman's mouth. The red spots are caused by an infection with the Herpes simplex (cold sore) virus. The infection is contagious and spread by direct contact with the blisters or their fluid. There are two types of herpes simplex virus; HSV1, which causes infections of the nose, mouth and face, and HSV2, which infects the genitals. There is no cure for the herpes simplex infection, but symptomatic outbreaks can be treated with the antiviral drug acyclovir (trade name Zovirax).
