Method of transmission

Most cases of syphilis are transmitted by sexual contact, but it is also possible to transmit through direct contact with active lesions in primary or secondary syphilis or through the passage at the placenta level. The transmission from the mother to the fetus can take place at any time of pregnancy and at any stage of the pregnant woman’s infection, being more frequent at the primary and secondary stage.

The higher risk of transmission is from people in the initial stages. In the initial stages of the disease, it can also be transmitted through the blood.

Risk groups

The risk of sickness is increased in people over the age of 24, in those with a low education level, those who have more sexual partners, those who do not constantly use condoms, in people with homosexual behavior and those with HIV infection.
