How the Body Eliminates Viruses: Immune Response and Antiviral Strategies

Viruses can be cleared from the host through several mechanisms:

The immune system recognizes viruses as foreign, producing antibodies that neutralize the virus and prevent infection of healthy cells.

Medications designed to inhibit viral replication reduce symptom severity and help clear infections.

This host-produced protein inhibits viral replication and protects uninfected cells.

High temperatures destroy viruses, making cooking and boiling effective for food safety.

UV light damages viral genetic material, commonly used for disinfection in healthcare settings.

Lysosomes fuse with viruses and break them down using hydrolytic enzymes.

Viruses can be expelled via the respiratory, digestive, or urinary tracts.
