Herpes zoster or shingles is caused by the reactivation of the virus, with vesicles located along one dermatome.

带状疱疹是由病毒重新激活导致的，皮损沿皮节呈带状排列。

And that reactivation of those neurons will make you remember the evening when you were cooking dinner in the kitchen.

而这些神经元的重新激活会让你想起在厨房做饭的那个晚上。

These can happen from a primary infection, but more commonly happen during reactivation when some of the virus can escape into the bloodstream and reach the brain.

这些可能由于原发性感染造成，但更多的见于复发，（当复发时）一些病毒经血液传播到大脑造成。

HSV can cause unique symptoms in immunocompromised individuals who tend to have more frequent reactivation, more severe symptoms, and a wider range of symptoms, like lesions in the esophagus or lungs.

在免疫功能受损的个体中，HSV会引起特异的症状，往往有更高的复发频率，更严重的症状，更多样的表现，比如造成食道或肺部的病变。
