Can some viruses remain dormant in the body for many year?
Yes, some viruses can remain dormant in the body for many years. For example, the herpes simplex virus can establish latency in nerve cells, becoming inactive and causing no symptoms until it reactivates later. Similarly, the varicella-zoster virus, which causes chickenpox, can lie dormant in the nervous system and later cause shingles. This ability to remain dormant can complicate treatment and contribute to recurrent infections.
When do viruses remain dormant in a cell?
Viruses can remain dormant in a cell until conditions become favorable for replication. Factors such as a weakened immune system or stress can trigger the virus to become active again.
What type of virus enters the cell and doesn't immediately attack?
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.
How long can tropical spastic paraparesis remain dormant?
Tropical spastic paraparesis (TSP), caused by the HTLV-1 virus, can remain dormant for many years, even decades, before symptoms appear. However, not everyone infected with HTLV-1 will develop TSP. Factors such as genetic predisposition and immune response can influence whether the virus becomes active and causes symptoms.
Does the Norwalk virus have a Lytic or Lysogenic cycle?
The Norwalk virus (Norovirus) does not have a lyosgenic cycle. It does not remain dormant as lysogenic viruses can. It is lytic and is considered virulent as many lytic viruses are. Most bacteriophages are lysogenic. See link below:
What is a hallmark of the virus group to which CMV belongs?
A hallmark of the virus group is the ability to infect a host and then become dormant. CMV can remain dormant for years. Even in periods without symptoms, the virus can still be periodically shed from the body in fluids like tears.

What effect will a virus in the lytic cycle have on an oranism?
The Norwalk virus (Norovirus) does not have a lyosgenic cycle. It does not remain dormant as lysogenic viruses can.
What is an example of an latent virus?

What does it mean when a virus can sleep?
When a virus is said to "sleep," it typically refers to its ability to enter a dormant state, often called latency. In this state, the virus is not actively replicating or causing disease, but it can remain in the host's cells without being detected by the immune system. This dormancy allows the virus to evade the host's defenses and can reactivate later, potentially causing infection again. This behavior is commonly seen in certain viruses, such as herpesviruses.
What is the inactive version of a virus?
Dormant.
What is a dormant virus?
Any virus that is not modifying a cells behavior is considered dormant; it may be in a cell but not active, or outside a cell (where it can't be active).
What are examples of latent diseases?
Latent diseases are infections that remain inactive or dormant in the body for long periods before becoming active. Examples include tuberculosis, which can stay asymptomatic in the lungs, and herpes simplex virus, which can lie dormant in nerve cells. Other examples are HIV, which can remain undetected for years, and varicella-zoster virus, responsible for chickenpox and later shingles. These diseases can reactivate under certain conditions, such as stress or immunocompromised states.
What virus can remain inactive for months of years?
The herpes simplex virus (HSV) is one example of a virus that can remain inactive for long periods, often for months or even years. After the initial infection, HSV can establish latency in nerve cells, where it remains dormant until reactivation triggers an outbreak. Other viruses, like varicella-zoster virus (which causes chickenpox and shingles), also exhibit similar latent behavior.
