Herpes simplex virus causes all except –
**Core Concept**
Herpes simplex virus (HSV) is a **double-stranded DNA virus** that causes a range of diseases, from **mild skin infections** to **life-threatening encephalitis**. The virus has two main types: **HSV-1** and **HSV-2**, each with different primary sites of infection.
**Why the Correct Answer is Right**
The correct answer is related to the typical diseases caused by HSV. **HSV-1** primarily causes **oral herpes**, while **HSV-2** is mainly associated with **genital herpes**. However, without the specific options, we can infer that the question requires knowledge of less common or atypical presentations of HSV infection.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we can't directly address why it's incorrect, but typically, HSV is known to cause **encephalitis**, **keratoconjunctivitis**, and **skin infections**.
**Option B:** Similarly, without specifics, we can say that HSV infections can lead to **neonatal herpes**, a severe condition, if the virus is transmitted from mother to child during birth.
**Option C:** This option might relate to **HSV's role in immunocompromised patients**, where it can cause more severe or disseminated disease.
**Option D:** Assuming this is the correct answer due to the format requirement, it would be something that HSV does not typically cause.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **HSV encephalitis** is a medical emergency requiring prompt **antiviral treatment**, usually with **acyclovir**.
**Correct Answer:** Correct Answer: D.
