Verified step by step guidance

1. Understand the definition of an acute viral infection: An acute infection is characterized by a rapid onset of disease, a relatively brief period of symptoms, and resolution within days to weeks.
2. Review the characteristics of each virus mentioned in the problem: Human immunodeficiency virus (HIV), Influenza virus (flu), and Varicella-zoster virus (chicken pox).
3. Consider the duration each virus remains in the body: HIV remains from initial infection until death, Influenza virus remains for around 14 days, and Varicella-zoster virus remains for years or until death.
4. Identify which virus aligns with the definition of an acute infection: The virus that remains in the body for a short period (days to weeks) is considered acute.
5. Conclude that the Influenza virus (flu), which remains in the body for around 14 days, fits the criteria for an acute infection.
