Introduction
After entering the bloodstream through minor skin wounds, syphilis primarily manifests as a localized indurated nodule on the genitalia, known as a chancre. This chancre feels firm—similar to cartilage—yet is painless, non-pruritic, and does not discharge pus. Consequently, patients often overlook it and fail to seek medical attention, allowing the infection to progress to secondary syphilis. If left untreated, secondary syphilis may further advance to tertiary syphilis.

Treponema pallidum is the causative agent of syphilis. What are the early symptoms of syphilis?

What Are the Early Symptoms of Syphilis?

After entering the bloodstream through minor breaks in the skin, Treponema pallidum primarily manifests as a localized indurated lesion on the genitalia—termed a “chancre” (hard chancre). This chancre feels firm, similar to cartilage, and is typically painless, non-pruritic, and non-suppurative. Due to its subtle presentation, patients often overlook it and delay seeking medical care, allowing the infection to progress to secondary syphilis. After several years, secondary syphilis may further advance to tertiary syphilis. Therefore, if you notice asymptomatic (non-itchy, non-painful) red macules on your hands or feet, rose-colored rashes on the trunk, or firm, nodular lesions on the penis, you should be highly vigilant and promptly consult a dermatologist or specialist in sexually transmitted infections (STIs).

Sexual transmission is the primary mode of spread. Clinically, syphilis is categorized into primary (Stage I), secondary (Stage II), tertiary (Stage III), latent, or congenital syphilis. Under the People’s Republic of China’s Law on the Prevention and Treatment of Infectious Diseases, syphilis is classified as a Category B notifiable infectious disease. Globally, over 12 million new cases of syphilis occur annually, with Treponema pallidum being the sole causative pathogen.
