If a student asks whether standard antivirals work against HIV, the answer is:

• A. Yes
• B. No
• C. Only in high doses
• D. Only for some strains

Answer: (B)

Antivirals are typically tailored to the replication mechanisms of specific viruses. HIV relies on a unique set of enzymes and steps—like reverse transcription, integration into the host genome, and proteolytic processing—that aren’t targeted by many drugs used for other viruses. Drugs that work for herpes or influenza, for example, don’t effectively block HIV replication at usual doses because HIV’s replication machinery isn’t the same as those viruses. To inhibit HIV, you need antiretroviral therapy designed to block its specific enzymes and processes, often used in combination to prevent resistance.
