Describe the last stage before escape of a viral infection?

Latency is the last phase of a viral infection before escape.

During latency, the virus exists within the body without inducing any symptoms but still maintains the potential for reactivation. The latency period can vary in length, ranging from a few weeks to several years, depending on the type of virus. During this stage, the viral genome is present but remains quiescent within the host cells, primarily residing in specific tissues or organs. The immune system may be unaware or unable to completely eradicate the latent virus, allowing for its persistence in the body. Factors that trigger viral reactivation can include weakened immune responses due to stress, aging, or immunosuppressive conditions, leading to the reemergence of active infection.
