True about Herpes virus -a) HSV encephalopathy is treated with acyclovirb) Oropharyngeal involvement is common in HSV -1c) Recurrent genital involvement is seen in HSV – 2d) Reccurence is rare in HSV – 1
First, I need to recall the basics of HSV. HSV-1 and HSV-2 are both herpes simplex viruses but differ in their usual sites of infection and recurrence patterns. HSV-1 typically causes oral infections (like cold sores), while HSV-2 is more associated with genital infections. However, there's some overlap now due to oral-genital contact.
Looking at option a: HSV encephalitis is indeed treated with acyclovir. Acyclovir is the standard treatment for HSV encephalitis, so this is correct. But wait, the question is about the true statements, so if option a is correct, then that's part of the answer.
Option b: Oropharyngeal involvement is common in HSV-1. Yes, HSV-1 usually causes oral infections, including oropharyngeal lesions. So this is true. So b is correct.
Option c: Recurrent genital involvement in HSV-2. HSV-2 is known for more frequent recurrences compared to HSV-1. So if the genital involvement is recurrent, that's HSV-2. So c is correct.
Option d: Recurrence is rare in HSV-1. Wait, HSV-1 can cause genital infections now too, and when it does, it tends to have fewer recurrences than HSV-2. So if d says recurrence is rare in HSV-1, that's true. But wait, the question is about which statements are true. So if d is true, then it's correct. But wait, the options are a, b, c, d. The correct answer is not given here. The user hasn't provided the correct answer yet. Wait, in the problem statement, the user says the correct answer is to be determined. Wait, the original question is presented with options A-D, but the user hasn't specified which is correct. Wait, the user provided the question and then says the correct answer is to be determined. But the user's task is to generate the explanation given the question and correct answer. Wait, looking back, the user provided the question and then the correct answer as "C. " but the letters are not filled in. Wait, the original input from the user shows the correct answer as ". " with nothing filled in. Wait, maybe there was a formatting issue. Let me check again.
The user's input shows:
