The way that the virus is reproduced is by infecting and killing the host cell and cloning themselves. This would mean that it cannot spread from cell to cell. But there is an exception to all this. when an infection goes through a lysogenic cycle, the virus gets planted into one of the host's chromosome. After this, when the host cell reproduce, the virus is also copied and thus two cells end up with the virus. Sorry it was so long, but I hope it answered your question.
Abstract. This paper is a continuation of recent attempts to understand, via mathematical modeling, the dynamics of marine bacteriophage infections. Previous authors have proposed systems of ordinary differential delay equations with delay dependent coefficients. In this paper we continue these studies in two respects. First, we show that the dynamics is sensitive to the phage mortality function, and in particular to the parameter we use to measure the density dependent phage mortality rate. Second, we incorporate spatial effects by deriving, in one spatial dimension, a delay reactiondiffusion model in which the delay term is rigorously derived by solving a von Foerster equation. Using this model, we formally compute the speed at which the viral infection spreads through the domain and investigate how this speed depends on the system parameters. Numerical simulations suggest that the minimum speed according to linear theory is the asymptotic speed of propagation.

A virus that has suddenly appeared or has recently come to the attention of medical scientists.
physical contact and not washing your hands
Viral and bacterial infections are both spread in basically the same ways. A person with a cold can spread the infection by coughing and/or sneezing. Bacteria or viruses can be passed on by touching or shaking hands with another person.Feb 5, 2014Found on Netdocter.

It depends on what virus it is. Some viruses, like the West Nile virus, aren't contagious. Other viruses are contagious.Yes, viral infections are contagious. If you cough on somebody or kiss someone you could spread it.
The medical terminology combining form meaning causing death is "thanato-."
Mononucleosis is a viral infection causing fever, sore throat, and swollen lymph glands, especially in the neck. Its spread by saliva and close contact.
No it is not, it is only spread by spores.

Both bacterial infections and viral infections can be contagious or not contagious. Some viral infections are not spread from human to human or are only rarely spread that way. TB is a contagious bacterial infection.

Viral marketing is also called viral advertising. It is a means of using mouth-to-mouth communications like social networks to spread a company's or brand's message through the Internet or email.
