The virus can reactivate and begin producing large amounts of viral progeny (the lytic part of the viral life cycle) without the host becoming reinfected by new outside virus, and stays within the host indefinitely. [2] Virus latency is not to be confused with clinical latency during the incubation period when a virus is not dormant.
Germ theory denialism is the pseudoscientific belief that germs do not cause infectious disease, and that the germ theory of disease is wrong. [1] It usually involves arguing that Louis Pasteur's model of infectious disease was wrong, and that Antoine Béchamp's was right.
The herpes virus can then exit this dormant stage and re-enter the lytic cycle, causing disease symptoms. Thus, while herpes viruses can enter both the lytic and lysogenic cycles, latency allows the virus to survive and evade detection by the immune system due to low viral gene expression. The model organism for studying lysogeny is the lambda ...
Flu viruses generally subside in warm weather, for reasons that aren't totally clear. Coronavirus may follow that pattern — or not. Will coronavirus go away in the spring?
RSV is respiratory syncytial (sin-SISH-uhl) virus, usually causes mild, cold-like symptoms, according to the federal Centers for Disease Control, and most people recover within a week or two.

Some viruses can "hide" within a cell, which may mean that they evade the host cell defenses or immune system and may increase the long-term "success" of the virus. This hiding is deemed latency. During this time, the virus does not produce any progeny, it remains inactive until external stimuli—such as light or stress—prompts it to activate.
Most mutations either make the virus “infect worse or have no effect,” Dr. Kasson says, but some make the virus infect people more efficiently or help it evade existing immunity—a.k.a. make ...
