Introduction to the 5 Transmission Paths of Syphilis: Diagnosis of Syphilis includes these 5 items

Syphilis is a chronic, systemic transmission disease caused by pallidum (syphilis) spirochetes. Mainly transmitted through sexual means, clinically it can manifest as primary syphilis, secondary syphilis, tertiary syphilis, latent syphilis, and congenital syphilis (fetal syphilis). It is a disease classified as Class B for prevention and control management in the "Law of the People's Republic of China on the Prevention and Control of Infectious Diseases".

Syphilis is a chronic contagious disease. The pathogen of syphilis is the pale spirochete, which has serious pathogenicity to humans and invades any organ, producing various symptoms. Treponema pallidum only infects humans, so syphilis is the only source of infection. The transmission route of acquired syphilis is mainly through sexual intercourse, with a few being transmitted through kissing or through the placenta to the fetus, causing the disease. Syphilis patients who do not receive treatment have the greatest infectivity within one year after infection, with the longer the disease period, the less contagious it becomes. After four years of infection, it is generally no longer contagious through sexual contact, but it can still be transmitted from fetus.

Introduction to 5 Transmission Paths of Syphilis

The transmission routes of syphilis are divided into

1. Bloodborne transmission

The course of syphilis is long, and Treponema pallidum can lurk in the patient's blood for a period of time. Especially for patients with latent syphilis, who are infected with pathogens but have no clinical manifestations, healthy individuals and other disease patients can be infected with syphilis by inputting blood and blood products provided.

2、 Indirect contact transmission

Contact with objects used by syphilis patients, such as clothing, blankets, items, supplies, tools, toilets, bath towels, etc., may be contaminated by the patient's secretions and infect the pale spirochete of syphilis. Healthy individuals who live closely with syphilis patients are prone to contracting syphilis when they come into contact with pathogenic bacteria in minor wounds.

3、 Placental transmission

If a pregnant woman is infected with syphilis, it can be transmitted to the fetus through the placenta during pregnancy. Director Shao of Changchun Ping An Urology Department introduced that pregnant women who suffer from syphilis are not detected and treated in a timely manner, or are not treated thoroughly. Syphilis pallidum can be transmitted to the fetus through placental blood circulation, causing the fetus to be infected with syphilis. Placental infections mainly occur during early syphilis in pregnant women.

4、 Sexual contact transmission

More than 90% of syphilis in clinical practice is transmitted through sexual contact with syphilitic patients. The methods of sexual contact include sexual activity, hot kissing, and skin contact. The skin and mucosa of the genital area of the human body are thin, with abundant blood vessels. During sexual intercourse, it is in an extremely congested state. Friction during sexual intercourse can cause minor damage, creating conditions for the invasion of syphilis pallidum.
