In brief: Varicella/Zoster

The virus is spread through direct contact with fluid from the rash blisters caused by shingles.
A person with active shingles can spread the virus when the rash is in the blister-phase. A person is not infectious before the blisters appear. Once the rash has developed crusts, the person is no longer contagious.
