Email: assignmentsamurai@gmail.com A nurse practitioner is educating a patient about herpes simplex virus (HSV) infections. Which of the following statements accurately describes a unique characteristic of HSV? Group of answer choices

• HSV primarily causes lesions in the frontotemporal region of the brain.
• HSV can become latent and reside within nerve ganglia, leading to potential recurrences.
• HSV infection heals within two to three weeks and never recurs.
• HSV infection in pregnant women always results in vertical transmission to the newborn.

  The correct answer is: HSV can become latent and reside within nerve ganglia, leading to potential recurrences.   Explanation: A key unique feature of herpes simplex virus (HSV) is its ability to establish latency in sensory nerve ganglia after primary infection, which allows for reactivation and recurrent outbreaks.

• HSV-1: Typically establishes latency in the trigeminal ganglion (oral herpes).
• HSV-2: Typically establishes latency in the sacral ganglia (genital herpes).

Why Not the Others?

• "HSV primarily causes lesions in the frontotemporal region of the brain":
  • While HSV can cause herpes encephalitis (most common in the temporal lobe), this is rare and not a defining feature of typical HSV infections.
• "HSV infection heals within two to three weeks and never recurs":
  • False—HSV lesions heal, but the virus remains dormant and can reactivate.
• "HSV infection in pregnant women always results in vertical transmission":
  • False—Transmission risk is highest during primary HSV infection near delivery, but not guaranteed.

Clinical Implications:

• Antivirals (e.g., acyclovir) can suppress recurrences but do not eliminate latency.
• Neonatal HSV is a severe complication but preventable with C-section if active lesions are present at delivery.

Thus, latency in nerve ganglia is the most accurate and unique characteristic of HSV.
