An immunocompromised child presents with fever and a rash of macules, papules, and pustules. What is the appropriate management?

• A. Hospitalize the child for intravenous acyclovir.
• B. Administer varicella immune globulin (VariZIG).
• C. Order intravenous immunoglobulin as an outpatient.
• D. Prescribe oral acyclovir for the duration of the illness.

Answer: (A)

In an immunocompromised child with fever and a rash that includes macules, papules, and pustules, this is most consistent with varicella that can progress rapidly in people with weakened immune systems. The best management is to hospitalize and start intravenous acyclovir promptly. IV antiviral therapy is stronger and reaches higher blood levels quickly, which is crucial to control viral replication and prevent serious complications such as pneumonia, hepatitis, or encephalitis that can occur in this group. Dosing is typically IV and more aggressive than oral therapy, with continuation based on clinical response and until the patient stabilizes. VariZIG is used for post-exposure prophylaxis in high-risk, susceptible individuals within a short window after exposure, not to treat an established infection. Intravenous immunoglobulin isn’t a standard treatment for varicella, and oral acyclovir, while useful for some nonimmunocompromised patients with milder disease, is not adequate for an immunocompromised child who has active infection. Isolation and supportive care are also important to prevent spread and manage symptoms.
