Can a virus hang out for long time in body without showing up?

Yes, a virus can hang out for a long time in the body without showing up. This is called a latent infection. During a latent infection, the virus is not actively replicating and causing symptoms, but it is still present in the body. The virus can reactivate later on, causing a recurrent infection.

Some examples of viruses that can cause latent infections include:

* Herpes simplex virus (HSV-1 and HSV-2)

* Varicella-zoster virus (VZV)

* Cytomegalovirus (CMV)

* Epstein-Barr virus (EBV)

* Hepatitis B virus (HBV)

* Human immunodeficiency virus (HIV)

Latent infections can be a problem for people with weakened immune systems. This is because a weakened immune system cannot effectively control the virus, which can lead to reactivation of the infection and more severe symptoms.

There is no cure for latent infections, but they can be managed with antiviral medications. These medications can help to prevent reactivation of the infection and reduce symptoms.
