How does a virus infect the body
WebA virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus. WebAfter the initial infection, the virus gets into the nerve roots and spreads to the sensory nerve ganglia, the junctions where nerves from different parts of the body come together. For the genital area, the ganglia are adjacent to the spinal cord in the lower back. For orofacial herpes (cold sores), the ganglia are located behind the cheek bone.
