The hands are one of the most common places for a scabies outbreak, especially in nursing homes. Since you may be handling contaminated linens, your hands are the most common place for the mite to gain a footing. They can then transfer to other parts of your body through scratching.
Plus, if you have scabies elsewhere and scratch it, you may get some of the mites and eggs under your fingernails. These can then spread on your hands.
Here are some pictures of scabies on hands:
