A 65-year-old man complains of lower back pain. For the past 3 days, he has had a sharp, burning pain in his lower back, which would radiate to his flank and, sometimes, all the way around to his abdomen. The pain comes and goes, feels like and "electric shock," is unrelated to activity and can be severe. He has had no injury to his back and has no history of back problems in the past. He has not experienced fever, urinary symptoms, or gastrointestinal symptoms. His examination, including careful back and abdominal examination, is normal. He is prescribed a nonsteriodal anti-inflammatory (NSAID) for the pain. The next day, he returns to the doctor stating that he thinks he has had an allergic reaction to the medication because he's developed a rash. The rash is in the area where he had the pain for which he was seen the day before. On examination now, he has an eruption consisting of patches of erythema with clusters of vesicles extending in a strip from his left lower back to the midline of his abdomen. 1. What is the name of the disease that is the cause of this rash? 2. What is the etiological agent of this disease? 3. What type of microbe causes this disease (bacteria, virus, protozoan..)? 4. Is this patient contagious while the vesicles are weeping? 4

**Case Study: Shingles Presentation and Diagnosis** A 65-year-old man complains of lower back pain. For the past 3 days, he has had a sharp, burning pain in his lower back, which would radiate to his flank and, sometimes, all the way around to his abdomen. The pain comes and goes, feels like and “electric shock,” is unrelated to activity and can be severe. He has had no injury to his back and has no history of back problems in the past. He has not experienced fever, urinary symptoms, or gastrointestinal symptoms. His examination, including careful back and abdominal examination, is normal. He is prescribed a nonsteroidal anti-inflammatory (NSAID) for the pain. The next day, he returns to the doctor stating that he thinks he has had an allergic reaction to the medication because he’s developed a rash. The rash is in the area where he had the pain for which he was seen the day before. On examination now, he has an eruption consisting of patches of erythema with clusters of vesicles extending in a strip from his left lower back to the midline of his abdomen. **Images:** *Image 1:* This image shows a portion of the patient's back where the rash has developed. There are clusters of red, inflamed patches likely intermixed with vesicles. ![Image showing rash on the patient's back](insertimageurl) *Image 2:* A close-up image of the rash detailing the distinct clusters of erythema with vesicular formations. ![Close-up of the rash](insertimageurl) **Questions:** 1. What is the name of the disease that is the cause of this rash? 2. What is the etiological agent of this disease? 3. What type of microbe causes this disease (bacteria, virus, protozoan…)? 4. Is this patient contagious while the vesicles are weeping? 5. Can this disease be prevented? **Discussion:** This case study describes the presentation, diagnosis, and management of a patient with shingles (herpes zoster), a viral infection caused by the reactivation of the varicella-zoster virus. The dermatomal rash and painful vesicular eruptions are characteristic of this condition. **Answers to Questions:** 1. The disease is called Shingles or Herpes Zoster. 2. The etiological agent is the Varicella-Zoster Virus (VZV). 3. VZ
