Detailed explanation-1: -Latent infection is characterized by the lack of demonstrable infectious virus between episodes of recurrent disease. Chronic infection is characterized by the continued presence of infectious virus following the primary infection and may include chronic or recurrent disease.

Detailed explanation-2: -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.

Detailed explanation-3: -A chronic infection is a type of persistent infection that is eventually cleared, while latent or slow infections last the life of the host. There is no single mechanism responsible for establishing a persistent infection; a key feature is reduction in host defenses and the ability of the virus to kill cells.

Detailed explanation-4: -When they come out of hiding, or “reactivate, ” latent viruses can cause transient (temporary) symptoms or persistent disease. For example, Herpesviruses are a large family of viruses that cause chicken pox, shingles, and more.
