What condition is HSV-1 primarily associated with?

HSV-1, or herpes simplex virus type 1, is primarily associated with cold sores, also known as fever blisters. This viral infection typically manifests as painful, fluid-filled blisters around the lips and mouth area. The virus is highly contagious and is usually transmitted through direct contact, such as kissing or sharing utensils. Cold sores tend to recur, especially during times of stress or illness, due to the virus becoming dormant and then reactivating.

In contrast to cold sores, other listed conditions have different causes and characteristics. Acne is primarily caused by clogged pores and hormonal changes, cankers are referred to as canker sores and are not caused by the herpes virus—rather, they appear as painful ulcers in the mouth. Eczema is a chronic skin condition characterized by inflammation and irritation of the skin and is not associated with HSV-1. Thus, the association of HSV-1 with cold sores highlights its significance in understanding viral infections that specifically affect oral health.
