Virus and Host Interaction

Virus and host interaction occurs when a virus invades a living organism to reproduce. The virus attaches to the host cell, injects its genetic material, and hijacks the cell's machinery to make copies of itself. This process can damage or destroy the host cell, causing illness or symptoms. The immune system then works to recognize and fight the virus. This interaction is a complex biological battle: the virus seeks to replicate, while the host defends itself. Understanding this process helps in developing vaccines and treatments to prevent or reduce infection severity.
