Shingles are the virus responsible for chicken pox. During primary infection, the virus infects a nerve and therefore remain in this inactive.
Herpes may remain inactive even for years without causing rashes characteristics. Can suddenly be reactivated, leading to the appearance of rashes along the underlying infected nerve. Rashes are likely to cause severe pain and itching.
The clinical picture of rashes is enough to give a safe diagnosis of the infection by the virus.
