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..
How long are viruses contagious for?
Most people will be infectious for around 2 weeks. Symptoms are usually worse during the first 2 to 3 days, and this is when you’re most likely to spread the virus.
What are the symptoms of a viral infection?

How do you tell if it’s viral or bacterial?
Your doctor often can diagnose you through a medical history and physical exam. The doctor may order blood or urine tests or a spinal culture to help pinpoint a viral or bacterial infection.
What triggers a virus?
The immune system produces special antibodies that can bind to viruses, making them non-infectious. The body sends T cells to destroy the virus. Most viral infections trigger a protective response from the immune system, but viruses such as HIV and neurotropic viruses have ways of evading the immune system’s defenses.
How do viruses hide in the body?
Until recently scientists believed that viruses acted independently. Now we know that up to 40 of them can form into vesicles, which are essentially membrane-bound packets or spheres. These membrane sacs act as a Trojan horse to pass through the body’s defenses.

Can a virus keep recurring?
In chronic viral infection, in contrast, viral replication and infectious particle production are continually maintained. For many such infections, recurrent episodes of high viral production and release interrupt relatively long periods of low-level viral replication.
How is a virus activated?
Most viruses, Trojan horses, and worms are activated when you open an attachment or click a link contained in an email message. If your email client allows scripting, then it is possible to get a virus by simply opening a message. It’s best to limit what HTML is available in your email messages.
