A virus that remains inactive for a time is said to be lysogenic.
When a virus enters a body but remains inactive, it is referred to as a "latent" infection. In this state, the virus may remain dormant within host cells without causing symptoms or replicating. Latent infections can reactivate later, leading to active disease. Examples include the herpes simplex virus and varicella-zoster virus.
The frequency of a wave remains unchanged when it enters a different medium. This means that the number of oscillations or cycles that the wave undergoes per unit time remains the same.
The streak of light created by a meteoroid entering the Earth's atmosphere is called a meteor. A meteorite is the remains of a meteoroid that did not vaporize after entering the Earth's atmosphere.
A dormant virus is a type of virus that enters the cell and remains inactive for a period of time before starting to replicate and cause symptoms. During this dormant phase, the virus may integrate its genetic material into the host cell's genome or remain in a latent state until conditions are favorable for replication.
When sound enters another medium such as a wall, the frequency or pitch of the sound remains constant. The velocity or speed of sound may change depending on the properties of the medium, but the frequency remains the same.
A virus outside a host cell is generally referred to as a virion. This is the inactive form of the virus that is unable to replicate until it enters a suitable host cell.

A person who enters by force without permission is commonly called a trespasser or an intruder.

A temperate phage is a type of phage that can enter an inactive prophage stage by integrating its DNA into the host cell's genome. In this stage, the prophage replicates along with the host cell's DNA and can be passed on to daughter cells during cell division.
Vaccine This is any solution that is prepared to cause immunity against a specific disease, usually employing a non-harmful form of the disease agent (the virus or bacteria), as killed or weakened (inactive) to stimulate antibody production.
