Are viral genes that are expressed immediately after the virus infects the host cell lytic or lysogenic?

Viral genes expressed immediately after infection are typically associated with the lytic cycle. In this cycle, the virus hijacks the host cell's machinery to replicate and produce new viral particles, leading to cell lysis and release of the virus. In contrast, the lysogenic cycle involves the integration of viral DNA into the host genome, where it can remain dormant before activating. Thus, immediate expression of viral genes indicates a lytic infection.
