Why would it be easier for a doctor to tell that someone has a viral infection when the virus is in the lytic cycle?

During the lytic cycle, a virus replicates rapidly within host cells, leading to cell lysis and the release of new viral particles. This aggressive replication often results in a more pronounced and acute symptomatology, such as fever, fatigue, and localized inflammation, making it easier for doctors to identify the infection. Additionally, the presence of viral particles and associated immune responses can be detected through laboratory tests, further aiding diagnosis. In contrast, infections in the lysogenic cycle may present with milder or no symptoms, complicating diagnosis.
