Herpes simplex viruses (HSVs) are highly host-adapted viruses that can cause a variety of diseases in human hosts. (a) herpes simplex virus type 1 (HSV-1) and (b) herpes simplex virus type 2 (HSV-2) are the two forms of HSVs (HSV-2). Both types share DNA homology, antigenic determinants, tissue tropism, and illness symptoms, but their epidemiology is distinct. HSV-1 is transferred predominantly by contact with infected saliva, whereas HSV-2 is transmitted through sexual contact or vaginal tract infection from an infected mother to her newborn child.
