What symptom is commonly associated with herpes simplex?

The symptom commonly associated with herpes simplex is the appearance of red, painful blisters or bumps. This condition is primarily known for causing outbreaks of sores, particularly around the mouth (oral herpes caused by HSV-1) and the genital area (genital herpes caused by HSV-2). During an outbreak, individuals may experience clusters of small, fluid-filled blisters that can be itchy and painful, often accompanied by other symptoms such as tingling or burning sensations in the affected area prior to the blisters appearing. This symptomatology is a hallmark of herpes simplex infections, distinguishing it from other skin conditions.

Other options refer to symptoms that do not align with a herpes simplex diagnosis; rashes that do not itch or dry patches on the skin suggest different dermatological issues, while swelling and redness around the eyes are typically indicative of conditions like conjunctivitis or allergic reactions rather than herpes simplex infections.
