Vaccine , there is no vaccine effective for prevention. Several vaccines based on treponemal proteins reduce lesion development in an animal model but research continues. Sex Condom use reduces the likelihood of transmission during sex, but does not eliminate the risk. The Centers for Disease Control and Prevention (CDC) states, "Correct and consistent use of latex condoms can reduce the risk of<unk>  only when the infected area or site of potential exposure is protected. However, a<unk>  sore outside of the area covered by a latex condom can still allow transmission, so caution should be exercised even when using a condom." Abstinence from intimate physical contact with an infected person is effective at reducing the transmission of<unk> . The CDC states, "The surest way to avoid transmission of sexually transmitted diseases, including<unk> , is to abstain from sexual contact or to be in a long-term mutually monogamous relationship with a partner who has been tested and is known to be uninfected." Congenital disease Portrait of Mr. J. Kay, affected with what is now believed to have been congenital<unk>  c. 1820 Congenital<unk>  in the newborn can be prevented by screening mothers during early pregnancy and treating those who are infected. The United States Preventive Services Task Force (USPSTF) strongly recommends universal screening of all pregnant women, while the World Health Organization (WHO) recommends all women be tested at their first antenatal visit and again in the third trimester. If they are positive, it is recommended their partners also be treated. Congenital<unk>  is still common in the developing world, as many women do not receive antenatal care at all, and the antenatal care others receive does not include screening. It still occasionally occurs in the developed world, as those most likely to acquire<unk>  are least likely to receive care during pregnancy. Several measures to increase access to testing appear effective at reducing rates of congenital<unk>  in low- to middle-income countries. Point-of-care testing to detect<unk>  appeared to be reliable although more research is needed to assess its effectiveness and into improving outcomes in mothers and babies. Screening The CDC recommends that sexually active men who have sex with men be tested at least yearly. The USPSTF also recommends screening among those at high risk.<unk>  is a notifiable disease in many countries, including Canada, the European Union, and the United States. This means health care providers are required to notify public health authorities, which will then ideally provide partner notification to the person's partners. Physicians may also encourage patients to send their partners to seek care. Several strategies have been found to improve follow-up for STI testing, including email and text messaging of reminders for appointments.
