What is the common feature of HSV-1 infections?

• A. Genital lesions
• B. Oral labial lesions
• C. Systemic infections
• D. Severe joint pain

Answer: (B)

The common feature of HSV-1 infections is the presence of oral labial lesions. Herpes Simplex Virus type 1 is primarily associated with infections that manifest as cold sores or fever blisters around the lips and mouth. These lesions can be painful and are often triggered by stress, illness, or sun exposure. Although HSV-1 can potentially lead to genital infections if transmitted through oral-genital contact, its most recognized and prevalent manifestation remains in the oral region. Other options, such as genital lesions, are more characteristic of HSV-2, which predominantly affects the genital area. Systemic infections are not typical for HSV-1, as this virus generally causes localized symptoms rather than widespread systemic illness. Severe joint pain is unrelated to HSV-1 infections, as this virus does not cause arthralgia or related symptoms. Therefore, the hallmark of HSV-1 remains its ability to produce those distinctive oral labial lesions.
