What is the primary infection of a non-immune person?
Varicella represents the primary infection in the nonimmune or incompletely immune person. During the primary infection, the virus gains entry into the sensory dorsal root ganglia. How the virus enters the sensory dorsal root ganglia and whether it resides in neurons or supporting cells are not completely understood.
