What is a common symptom of herpes simplex?

A common symptom of herpes simplex is the eruption of vesicles or blisters. This viral infection typically presents with clusters of small, fluid-filled blisters that can appear on various parts of the body, most commonly around the mouth or genital area. These vesicles are often painful and may break open, leading to ulceration and crusting as they heal.

The characteristic formation of these blisters is due to the nature of the herpes virus, which causes inflammation in the skin and mucous membranes, leading to the typical symptoms associated with outbreaks. The presence of vesicles is a key diagnostic feature of herpes simplex infections, making it a defining symptom of the condition.

Other symptoms associated with the virus may include itching or tingling sensations before the blisters appear, but the vesicle eruption is a hallmark of the infection.
