Herpes zoster (shingles) on the back

This photograph shows clusters of blisters (vesicles) and redness (erythema) caused by herpes zoster (shingles). The pattern follows a "dermatome" (see the dermatome picture). The area may burn or sting before the appearance of these vesicles. Early treatment with acyclovir (within 24 hours of the appearance of the vesicles) may prevent progression or reduce the time the infection is active (duration).
