Doxycycline as a possible PEP for bacterial sexually transmitted infections
Syphilis is a bacterial infection caused by Treponema pallidum, which results in substantial morbidity and mortality. It is a sexually transmitted infection (STI) that is generally transmitted by contact with infectious sores on the genitals, anus, rectum, lips, or mouth; through blood transfusions, or through mother-to-child transmission during pregnancy.
The correct and consistent use of condoms significantly reduces the risk of infection.
Mother-to-child transmission of syphilis (congenital syphilis) is preventable and can be achieved through early detection and treatment.
Women of childbearing age and pregnant women should be tested for syphilis and other STIs (HIV, Hepatitis B), as well as their sexual partners, to reduce the incidence of these sexually transmitted infections and achieve the birth of healthy children.
