After the first episode, the virus is not killed, but stays in the dormant state in the spinal nerve roots only to appear again when the circumstances in the body become favorable.

During the first episode there is appearance of rash followed by fluid filled blisters within two to three days. They form scabs within a week. During this period patient may complain of malaise, headache, burning pain around the affected area.
