What is a hidden virus during the latency period?

A hidden virus during the latency period refers to a virus that has entered a host's body and established a dormant or inactive state, where it is not actively replicating or causing symptoms. This latency allows the virus to evade the immune system and can persist for long periods, sometimes reactivating later to cause illness. Examples include the herpes simplex virus and varicella-zoster virus, which can remain hidden in nerve cells before re-emerging.
