The causes for zoster remain largely unknown. Psychological stress is one commonly considered risk factor. We used self-controlled case series methods to look for increases in zoster following death or catastrophic health event occurring in a previously healthy spouse. We found no increase, although this stressor led to increased mental health visits.
