Detailed explanation-1: -Some enveloped viruses enter the cell when the viral envelope fuses directly with the cell membrane. Once inside the cell, the viral capsid degrades, and then the viral nucleic acid is released and becomes available for replication and transcription.
Detailed explanation-2: -Active Viruses: After entering a cell, an active virus immediately goes into action. The virus’s genetic material takes over cell functions, and the cell quickly begins to reproduce. When it is full of new viruses, the host cell bursts open, releasing hundreds of new viruses as it dies.
Detailed explanation-3: -It has been known for decades that once a virus gets inside a cell, it hijacks the cellular processes to produce virally encoded protein that will replicate the virus’s genetic material.
Detailed explanation-4: -Latent Viruses & Reactivation This can occur when there is a specific trigger such as a different infection that distracts the immune system, and or when an external stimulus reaches the latent reservoir cells, ‘awakening’ the viral genome to start producing active viral particles rather than staying quiet.
