What are the differences between chickenpox and shingles?

Chickenpox is an acute infectious disease caused by the initial infection of herpes zoster virus through respiratory tract and close contact. The rash is mainly distributed concentrically, surrounded by redness and easy to rupture. When herpes occurs, herpes zoster virus lurks in the sensory deep meridian segment, which is caused after activation. The peripheral nerve distribution of rash inflammation is accompanied by neuralgia.
