Which STD is known to cause genital blisters?

Genital herpes is the correct choice as it is specifically associated with the development of genital blisters. The primary cause of genital herpes is the herpes simplex virus (HSV), which can lead to painful, fluid-filled blisters in the genital area. These blisters eventually break, leading to sores that can be quite uncomfortable.

When infected, individuals may experience an outbreak characterized by these blisters, which can recur over time. The presence of these blisters is a hallmark sign of this infection, differentiating it from other sexually transmitted diseases that may not exhibit blisters or lesions as a primary symptom. In contrast, conditions such as chlamydia, gonorrhea, and syphilis do not typically present with blisters but rather with different symptoms, such as discharge, pain during urination, or ulcer-like sores in the case of syphilis, which can be mistaken for other conditions but do not lead to the blisters characteristic of genital herpes. Understanding these distinctions is key to recognizing and diagnosing STDs effectively.
