Viral and host replication-related processes

Viral and host replication-related processes refer to the collective set of biochemical and cellular events required for a virus to infect a host cell, replicate its genome, and produce new progeny (NIH, 2023). This encompasses both viral-encoded proteins, such as RNA-dependent RNA polymerases and proteases, and host-cell factors like ribosomes, chaperones, and lipid membranes that the virus hijacks for its own life cycle (Nature Reviews Microbiology, 2020). Because it describes a broad category of biological phenomena rather than a single molecular entity, it is generally classified as a process-level grouping rather than a discrete therapeutic target (PubMed, 2021). Drugs acting on these processes typically aim to disrupt viral assembly or genome duplication while minimizing damage to the host's own replication machinery. Therapeutic challenges associated with this category include the potential for host cell toxicity and the rapid evolution of viral resistance (StatPearls, 2023).
