What makes viral infections different to defeat?

Viral infections are challenging to defeat because viruses hijack host cells to replicate, making it difficult for the immune system to target them without harming healthy cells. Unlike bacteria, which can often be treated with antibiotics, viruses rely on the host's cellular machinery, necessitating different therapeutic approaches, such as antiviral medications or vaccines. Additionally, viruses can mutate rapidly, allowing them to evade immune responses and complicating treatment and prevention efforts. This adaptability and reliance on host cells make viral infections particularly resilient.
