      Syphilis is a very harmful sexually transmitted disease disease , understanding its transmission routes is crucial to preventing and controlling the spread of syphilis. The following is a detailed introduction to the common transmission routes of syphilis.

    Sexual contact transmission

      unprotected sex: Unprotected sex is one of the main ways of spreading syphilis. During sexual contact, Treponema pallidum can pass skin Or microscopic damage to the mucous membrane enters the human body, causing infection. High-risk sexual behaviors such as multiple sexual partners and irregular sexual partners will greatly increase the risk of syphilis infection.

    mother-to-child vertical transmission

      placental infection: Pregnant women with syphilis can be infected through the placenta by Treponema pallidum in their bodies fetus , the placental infection rate is higher. This may lead to congenital syphilis in the fetus, causing premature birth , miscarriage, stillbirth or various congenital malformations after birth and other serious consequences.

      birth canal contact infection: During delivery, when the fetus passes through a syphilis-infected birth canal, the skin or mucous membranes come into contact with Treponema pallidum in the birth canal, which can also cause infection.

      Transmission during breastfeeding: Although relatively rare, a nursing mother who has syphilis can also pass Treponema pallidum through her milk to baby

    Bloodborne

      Shared syringes: Sharing syringes is an important cause of blood-borne transmission of syphilis among some drug users. If a syringe has been used by someone infected with syphilis and is then used by someone else, the treponema pallidum can enter the new user's body through the bloodstream.

      transfusion infection: Syphilis can also be contracted by transfusion of blood or blood products contaminated with Treponema pallidum. However, formal medical institutions are currently very strict about blood transfusion screening, and this transmission route has been relatively rare.

    indirect contact transmission

      Contact with patient secretions: If you come into contact with the chancre secretions of a syphilis patient, you may be infected with syphilis if your skin or mucous membranes are damaged. For example, when sharing personal items such as towels, clothing, and tableware with patients, there is a risk of infection if the items are contaminated by the patient's secretions.

    hospital-acquired infection

      Medical device contamination: In medical operations, if medical equipment is not thoroughly disinfected and contaminated by Treponema pallidum, it may lead to hospital-borne infections. For example, syringes, surgical instruments, etc. that have not been strictly sterilized.

      Syphilis is a chronic, systemic sexually transmitted disease caused by Treponema pallidum. Different transmission routes have different characteristics and risks. We need a comprehensive understanding to better prevent syphilis.
