Snakebite is shingles, which is now found to be primarily due to nerve damage caused by infection with the varicella zoster virus. Chickenpox occurs if the varicella zoster virus is contracted at a young age. An insidious infection may exist after the chickenpox has healed. The herpes zoster virus is latent in the nerve roots, but in case of stress, fatigue or immune system decline the varicella zoster virus can replicate, thus causing the corresponding neurohemorrhage and even upstream to the skin, bringing about manifestations of skin damage such as blisters along the nerve travel. Therefore, it is recommended to avoid exertion, pay attention to rest, improve the body’s immunity, and take oral antiviral medication. At the same time, in order to avoid infection, it is important to change clothes regularly.
