Can you spread Grover's disease by touch?

As of 2015, the medical community is unsure of how Grover’s disease spreads, but believes it relates to skin trauma cause by sun damage. In one case, Grover’s disease was associated with follicle mites, which are parasites, according to the National Organization for Rare Disorders.

Grover’s disease appears in the form of a rash that appears on the chest and back. It is more common in men over age 40. NORD describes the disease as dissolving the cement that holds skin cells together. This causes the formation of small blisters. The disease usually heals on its own, but can last a few weeks to several months.
