Final answer:
Early treatment of herpes zoster with antivirals like acyclovir can lessen symptom severity and duration, reduce the risk of postherpetic neuralgia, and prevent complications in immunocompromised patients.
Step-by-step explanation:
The early treatment of herpes zoster, commonly known as shingles, is highly beneficial. By administering antivirals such as acyclovir, one can significantly reduce the severity and duration of symptoms. Early intervention also diminishes the risk of developing postherpetic neuralgia, a painful condition that can persist even after the skin lesions have healed. Moreover, in immunocompromised individuals, early treatment can prevent the spread of the virus to other organs, potentially averting more serious complications.
