Which of the following typically describes a symptom of Herpes?

Fever blisters are indeed a common symptom of herpes, particularly in cases of oral herpes, which is primarily caused by the herpes simplex virus type 1 (HSV-1). These blisters appear on or around the lips and are often characterized by painful, swollen sores that can be unsightly and uncomfortable. The appearance of fever blisters is usually triggered by various factors, including stress, illness, or sun exposure, and they may recur multiple times throughout a person's life.

In contrast, while joint pain, weight loss, and night sweats can be associated with various medical conditions, they are not classic symptoms of herpes. Joint pain may indicate conditions like arthritis or autoimmune disorders, weight loss might reflect issues such as metabolic disorders or chronic diseases, and night sweats are often linked to infections or hormonal changes. Thus, fever blisters stand out as the most directly related symptom to herpes.
