Antiviral drug

Antiviral drugs are a class of medication used specifically for treating viral infections.

Like antibiotics, specific antivirals are used for specific viruses.

Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotics, anti-fungal and anti-parasitic drugs.

They are relatively harmless to the host, and therefore can be used to treat infections.
