Preventive measures against shingles include vaccination, avoiding contact with people with chickenpox and shingles, and adjusting lifestyle habits. 1. Vaccination: If conditions permit, shingles vaccine can be inoculated, which can reduce the probability of chickenpox-herpes zoster virus infection, and is a more effective way to prevent shingles. 2. Avoid contact with chickenpox patients and shingles patients: patients should avoid contact with chickenpox patients to prevent the occurrence of chickenpox, thus avoiding the incubation of varicella-zoster virus in the body, leading to the onset of shingles. If there are patients with herpes zoster around, frequent contact with them should be avoided, because the fluid in herpes may be infectious and may induce chickenpox after contact. 3. Adjustment of living habits: In daily life, we should eat regularly, adjust living habits, avoid smoking and drinking, avoid staying up all night, develop good habits of work and rest, regular physical exercise, reduce psychological pressure, improve physical fitness and immunity. It is recommended that patients with herpes zoster go to a regular hospital in a timely manner, comprehensive examination and standardized treatment.
