Why are there no medicines to destroy a virus?

Viruses are not living organisms; they require host cells to replicate, making it challenging to create medications that target them without harming the host's cells. Antiviral drugs often focus on inhibiting viral replication or boosting the immune response rather than directly destroying the virus. Additionally, the high mutation rates of viruses can lead to resistance against antiviral therapies, complicating treatment efforts. As a result, developing effective antiviral medications is a complex and ongoing challenge in medicine.
