Viral DNA is incorporated into a host cell, replicated there, and then new viruses are released. This process is known as viral infection.
The majority of viral infections usually resolve on their own. However, factors such as the individual's age, immunity, and other pre-existing disorders will largely determine the virulence and eventual recovery.
Viruses are unicellular organisms having protein-coated protein genetic material, such as DNA or RNA.
The viral illness's symptoms are brought on by host immunity-related tissue damage.
The development of virulence, or the extent to which a pathogen injures, kills or otherwise lessens the fitness of its host.
