Can condoms completely isolate the transmission of syphilis? What are the correct measures to prevent syphilis

In recent years, there has been a surge in syphilis infections in Japan, especially among women, which doubled in 2015 from the previous year.

According to Japanese media reports, syphilis is a contagious disease caused by bacteria, mainly transmitted through sexual activity. After infection, heat rash and skin ulcers appear in genital and lip areas, which can cause redness throughout the body. After the condition worsens, it may even cause symptoms such as paralysis. According to data, the number of syphilis infected individuals in Japan reached nearly 220000 in 1948, and the number of people affected by treatment drug development decreased sharply thereafter. Since the 1990s, the number of infected individuals has reached below 1000, and since then it has remained almost flat. However, since 2010, there has been a trend towards an increase in syphilis infections, with over 2600 people last year.

The report states that the increase in female infections is particularly significant. As of October 2015, the number of infected women had doubled from the same period the previous year, reaching 574, with 76% of the population aged 15 to 35.

Due to the increase in infections among young women, the transmission of syphilis through the placenta to the fetus after pregnancy is a concern. In addition to causing risks such as miscarriage and stillbirth, infections can also cause congenital syphilis in newborns.

Using condoms and 30% of the middle hands

Treponema pallidum is abundant on the surface of skin and mucosal damage, as well as in saliva, milk, semen, and urine. After entering the human body from the damaged skin and mucosa, it invades nearby lymph nodes within a few hours. Within 2-3 days, blood circulation spreads throughout the body, with a latent period of about 3 weeks. The initial sore at the invaded site is syphilis. Afterwards, the body produces antibodies, most of the spirochetes are killed, and the prickly heat naturally disappears, entering an asymptomatic incubation period, which is a stage of latent syphilis. Those who relapse within 6 months to 2 years are referred to as secondary recurrent syphilis.

Due to the fact that syphilis is not painful or itchy, and can self heal even if a rash occurs, it is not easy to attract the patient's attention. A graduate student from a certain university was found to have syphilis while donating blood. She described herself as suffering from rape and did not go to the hospital for examination and treatment afterwards. As a result, she was unaware of the infection and had already developed into Phase II by the time it was detected. According to a survey, first-stage syphilis in men is related to women, with a probability of 60% to 70% of women being recruited, and even condom use has a 30% failure rate.

Not washing hands and shaking hands after defecation can also be infected
