| Initial infection with HSV-1 is caused by contact with mucosal surfaces or abraded skin (Whitley & Roizman, 2001) in regions such as the lips, mouth, and skin above the waist (Nahmias, Keyserling & Lee, 1989). An individual can be affected with HSV-1 through close nonsexual contact with an affected individual such as kissing (even on the cheek), sharing utensils and sharing drinks, as the virus can remain viable for a brief period of time on skin, clothing and plastics (Fatahzadeh & Schwartz, 2007). An individual is most contagious when they are exhibiting cold sores or lesions, but is still contagious without showing symptoms. | Initial infection with HSV-1 is caused by contact with mucosal surfaces or abraded skin (Whitley & Roizman, 2001) in regions such as the lips, mouth, and skin above the waist (Nahmias, Keyserling & Lee, 1989).

| Whether or not the virus using endocytosis or fusion at the plasma membrane is dependent upon individual cell types that they encounter. In Vero and Hep2 infected cells, there is no preference. However, in CHO, HeLa, RPE, human epidermal keratinocytes and KCjE cells, there is a preference for endocytosis.
