Impact on Quality of Life and Burden of Disease in Adults With Herpes Zoster

Impact on quality of life and disease burden in adults with herpes zoster Contents

HYPOTHESIS AND OBJECTIVES OF THE STUDY 3.1 Hypothesis: Herpes zoster significantly affects the quality of life of those who suffer from it with a high disease burden.

3.2 Primary outcomes: To measure the quality of life of patients with a history of herpes zoster who attend the immunization unit of the Fundación Jiménez Díaz University Hospital.

3.3 Secondary outcomes

1. Evaluating the quality of life according to the location of the zoster (postherpetic neuralgia, ophthalmic zoster, etc.)

2. Evaluating the effectiveness of the vaccine against herpes zoster in terms of number of episodes, severity and quality of life.

3. Evaluating the economic impact and disease burden in terms of morbidity and mortality in adult with herpes zoster
