How to prevent herpes zoster infection

Herpes zoster is mainly caused by varicella zoster virus infection. This virus first infects the human body as chickenpox, then lurks in nerve roots. When the body's immunity decreases, it will wait for an opportunity to attack, and the next infection will appear as herpes zoster. Herpes zoster is not so infectious. The virus is contained in the blister fluid, so contact with these blisters may be contagious. In life, pay attention to the patient's clothing to be washed separately, if there are relatively small infants at home to pay attention to isolation, in the care of the patient's skin also pay attention to good protection.
