Causes of herpes zoster

The cause of herpes zoster may be related to recent fatigue, fatigue, and decreased immunity. The pathogen of herpes zoster is varicella zoster virus, which can cause chickenpox or latent infection after initial infection. The virus lurks in nerve cells in the body. After the body's immunity is lowered, the virus will be activated to cause localized erythema, and then miliary pimples, blisters, and pustules will appear on the basis of erythema. It is usually transmitted through the respiratory tract and can be protected by wearing a mask. This is the cause of herpes zoster.
