Fusion is the step in which the virus merges with the host membrane to release its genome—critical for entry and thus a prime target for antivirals like enfuvirtide.

**Fusion Is the Step in Which the Virus Merges with the Host Membrane to Release Its Genome—Critical for Entry and the Target of Key Antiviral Therapies** In the intricate dance of viral infection, one moment stands as a make-or-break threshold: when a virus fuses with the host cell membrane, releasing its genetic payload to begin the next phase of replication. This fusion step is not only a marvel of molecular biology but also a vital point of intervention for antiviral treatments. Understanding how this fusion unfolds offers crucial insight into both viral behavior and cutting-edge therapeutic strategies. Recent interest in this process is growing, particularly within the US biomedical and public health communities, driven by ongoing research into viral entry mechanisms and the development of targeted antivirals. The fusion step marks the moment a virus gains unauthorized access to a host cell, making it a strategic target for disrupting infection before it takes hold—especially relevant as new therapies evolve. ---
