Through unprotected sex: 95-98% of people with syphilis are infected by sexual partners. The skin and mucous membranes on the genitals of the patient are often damaged, the sores secrete a lot of fluid containing syphilis spirochetes. In addition, other contacts such as oral sex can also cause infection. Indirect syphilis infection: Although this route of infection is uncommon, it is entirely possible. When there is contact with the personal items of an infected person such as sharing underwear, personal items, toilets and towels... These items can contain syphilis bacteria and spread to the patient. Good people share furniture. Besides, if a person with syphilis lives with a healthy person, just a small scratch in contact with the object of a healthy person will be very easy to infect syphilis bacteria. Transmission through blood transfusion: If a person has blood that carries syphilis spirochetes, the recipient will also carry the disease. An infected person will not have early stage symptoms of syphilis but directly have stage 2 symptoms of the disease. Syphilis is transmitted from mother to child through the placenta and birth canal: If a pregnant woman has syphilis without timely detection and treatment or incomplete treatment, syphilis bacteria can enter the placenta through the placenta. fetus infects the fetus. When a fetus is born vaginally and the mother has previously been infected with syphilis bacteria, the syphilis bacteria can be transmitted to the fetus leading to the baby being infected with syphilis bacteria.

After an incubation period of 2-4 weeks, syphilis will progress in three stages.

Syphilis can cause the appearance of papules, blisters, sores on the skin and mucous membranes. Stage 3: Stage 3 syphilis can occur about 3-15 years after the symptoms of the stage. Syphilis bacteria grow in internal organs such as the brain, liver, cardiovascular muscles ..., causing different symptoms depending on the part of the body infected with syphilis.

Patients always feel the need to urinate but cannot urinate, leading to urinary retention and incontinence.
