Introduction
Patients in the early stage of sexually transmitted infections (STIs) often develop chancres—single, painless ulcers on the external genitalia with smooth surfaces. In cases of gonorrhea, patients typically exhibit abnormal vaginal or urethral discharge, commonly yellowish-green purulent secretions, accompanied by local stinging pain. Other STIs include genital herpes. During the initial phase of infection, clusters or scattered small vesicles appear, often associated with local burning or stabbing pain.
Today, some male and female patients neglect safe sexual practices and engage in unprotected sex with multiple partners, thereby increasing their risk of contracting sexually transmitted infections (STIs). Many patients are unaware of the symptoms associated with STIs—what signs typically appear during the early stages?
What Are the Early Symptoms of Sexually Transmitted Infections?
In the early stage of syphilis, patients commonly develop a hard chancre—a single, painless ulcer on the external genitalia with a smooth surface. In cases of gonorrhea, abnormal vaginal or urethral discharge is typical, often appearing as yellowish-green purulent fluid, accompanied by local burning or stinging sensations. Genital herpes is another STI; its initial presentation includes clusters or scattered small vesicles, often associated with burning or sharp pain at the affected site. Condyloma acuminatum (genital warts) is also an STI; in its early phase, patients typically present with tiny, grain-sized papules, usually asymptomatic.
Sexually transmitted infections are primarily spread through sexual contact. Common STIs—including syphilis, HIV/AIDS, gonorrhea, non-gonococcal urethritis, and genital herpes—are predominantly transmitted via sexual intercourse. Although other transmission routes exist, they are not primary modes of infection. For instance, gonorrhea and condyloma acuminatum may be indirectly transmitted through close personal contact—for example, via contaminated personal items such as undergarments, towels, washbasins, or toilet seats. Syphilis and HIV can also be transmitted from mother to child (vertical transmission).
There are numerous types of STIs, each requiring distinct treatment approaches. Patients should visit a hospital’s STI clinic for comprehensive serological testing—including tests for syphilis, HIV, gonorrhea, and chlamydia—to accurately diagnose the specific infection and select appropriate therapy. Self-treatment or blind medication use is strongly discouraged. Additionally, clinicians should carefully assess presenting clinical symptoms and tailor treatment accordingly. To prevent transmission, avoid close physical contact with others. We hope this information proves helpful!
