Can viruses be inactive?
Viruses can lay dormant, also referred to as “viral latency” which means a virus has the ability to remain inactive for a period of time within its host.
Since the virus has found a home within its cell, it only needs to be triggered to become active.
The five most common dormant diseases include the following..
Can a virus trigger another virus?
How herpes and other dormant viruses ‘reactivate’ explained in new study. Scientists have found that interactions between different viruses can trigger dormant viruses to reactivate and cause disease.
What viruses can reactivate?

Can viruses produce toxins?
For many years it’s been known that the fever, achiness and other symptoms you feel during the flu are triggered by a viral molecule that travels through the body acting like a toxin.
How do you fight a viral infection?
For most viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus. Antibiotics do not work for viral infections. There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.
What activates a dormant virus?
When HSV replicates in skin cells, it eventually heads toward a sensory nerve. When it reaches the neuron’s nucleus, it does not go through the same lytic infection cycle. Instead of replicating, it does something unusual – the virus goes dormant. This is called a latent infection.
Do viruses lay dormant in your body?
Dormant viruses are not new phenomena. Herpes viruses are often never fully eradicated from the body, and are instead subdued by the immune system. The herpes virus that causes chickenpox and shingles (VZV), for example, remains in our spinal cord cells for life.
Can you ever get rid of a virus?
Viruses are deadly. They kill twice as many people as cancer does – around 15 million people every year. Vaccines have saved many lives, but for most viruses there is no cure. Understanding how viruses work and learning how the human immune system deals with them is critical to finding new treatments.
Can you have a viral infection for years?
Some viruses, such as hepatitis B virus and hepatitis C virus, can cause chronic infections. Chronic hepatitis can last for years, even decades.
Can a viral infection keep coming back?
Because infection does not kill cells, a persistent infection ensues. Many infections persist because viral replication interferes with the function of cytotoxic T-lymphocytes (CTLs), immune cells that are extremely important for clearing viral infections.
