Amantadine and oseltamivir are used to treat infections caused by which virus family?

Explanation:
Antiviral drugs here are specific for influenza viruses, which belong to the Orthomyxoviridae family. Amantadine blocks the M2 ion channel required for uncoating in influenza A, so it stops early replication (not effective for influenza B). Oseltamivir inhibits neuraminidase, preventing release of new viral particles and thus spread within the respiratory tract; it works against both influenza A and B. This specificity means these drugs target influenza infections rather than herpes, coronavirus, or rhinovirus infections.
