Which sexually transmitted infection is caused by a herpesvirus and typically presents with blister-like lesions on the genitals?

• A. Chlamydia
• B. Genital herpes
• C. Gonorrhea
• D. Syphilis

Answer: (B)

Genital herpes is a herpesvirus infection that classically presents with blister-like lesions on the genitals. The lesions are usually grouped vesicles on an inflamed base, are painful, and often rupture to form ulcers; many patients also notice a prodrome of tingling or burning before the lesions appear. This vesicular, painful pattern is distinctive among the common STIs: chlamydia and gonorrhea more often cause discharge or dysuria without vesicular lesions, while syphilis typically begins with a painless chancre rather than painful blistering. Management involves antiviral therapy (such as acyclovir, valacyclovir, or famciclovir) to shorten outbreaks and reduce transmission, with possible suppressive therapy for recurrent disease. Transmission can occur even when lesions are not present due to viral shedding.
