Back to Sexual health. Oral sex is the stimulation of the genitals using the mouth and tongue. You can catch an STI if you have just one sexual partner. However, the more partners you have, the greater the risk of catching an infection.
Syphilis remains widespread worldwide, with increasing rates among men who have sex with men. This paper reviews available evidence regarding syphilis transmission, including data on: sexual transmission transmission probability per sexual partnership , vertical transmission, transmission via blood products and organ donation, and other rare modes of transmission. In addition, host susceptibility to syphilis infection is discussed. Syphilis screening and treatment, condoms and risk-reduction counselling and how they modify syphilis transmission dynamics are considered. The global burden of syphilis infection is high, with an estimated The rate of spread of syphilis in a population is related to the transmission probability per sexual partnership, the average rate of acquisition of sexual partners and the duration of infectiousness. In this paper, we will review the literature on syphilis transmissibility and susceptibility, discuss how prevention efforts can alter syphilis transmission and outline key unanswered questions and areas for future research.
Syphilis is a bacterial infection. Of those, 35, were primary and secondary syphilis , or the earliest stages of the infection. Syphilis is typically spread through person-to-person contact, such as through sexual activity. This includes vaginal, anal, or oral sex. When syphilis is spread during oral sex, bacteria enter a cut or opening in the lining of the lips or mouth.
This means that oral sex using the mouth, lips, or tongue can pose similar risks as other sexual activities. The only way to reduce your risk for transmission is to use a condom or other barrier method for every sexual encounter.
