Question: What Activates A Virus?

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?

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.
