This article provides an overview of the causes, symptoms, prevalence, and impact of syphilis today. It also emphasizes the importance of getting tested for syphilis and other sexually transmitted infections (STIs) and of taking preventative measures, such as practicing safe sex, limiting sexual partners, and getting vaccinated.


Syphilis is a sexually transmitted bacterial infection that has affected millions of people worldwide. Although syphilis is treatable with antibiotics, it continues to remain a public health concern due to its high prevalence in certain populations, particularly among men who have sex with men and communities with low access to healthcare services. In this article, we will provide a thorough overview of syphilis, including its causes, risk factors, symptoms, prevalence, and prevention.

The Causes and Risk Factors of Syphilis

Syphilis is a bacterial infection caused by Treponema pallidum. The bacteria can enter the body through open sores or cuts in the skin or mucous membranes, typically during sexual activity. It can also be transmitted from an infected mother to her child during childbirth. Syphilis transmission can occur through vaginal, anal, and oral sex.

Anyone who is sexually active can get syphilis. However, certain populations may be more at risk for contracting the infection. Men who have sex with men, individuals who engage in unprotected sex, and those with multiple partners are more prone to syphilis. Additionally, individuals with weakened immune systems, such as people living with HIV, are also at a higher risk for contracting syphilis.

The Symptoms and Stages of Syphilis

Syphilis has four stages, each with distinct symptoms. These stages include:

Primary syphilis: This stage typically begins with a painless sore or ulcer known as a chancre. The chancre appears at the site of infection, such as the genitals, anus, or mouth, and can last for three to six weeks.

Secondary syphilis: After primary syphilis goes untreated, it progresses to secondary syphilis, characterized by a rash that can appear on the whole body, including palms and soles. Other symptoms of secondary syphilis include fever, fatigue, sore throat, and swollen lymph nodes.

Latent syphilis: This stage has no visible symptoms, but the bacteria can still be present in the body and cause damage to various organs, including the brain, heart, and nervous system. Latent syphilis can last for years, and individuals may not realize they have the disease.

Tertiary syphilis: This stage occurs when syphilis goes untreated for many years, causing severe complications that can damage the heart, brain, and other organs. Symptoms of tertiary syphilis include memory loss, difficulty speaking, and even blindness and paralysis.

If you suspect you may have contracted syphilis, it is essential to get tested immediately. A healthcare provider can diagnose syphilis by performing a blood test or examining the suspected sore or ulcer. Early diagnosis is crucial, as syphilis is easier to treat in its early stages.

The Prevalence and Impact of Syphilis Today

Syphilis remains a prevalent sexually transmitted infection worldwide. In the United States, syphilis rates have been steadily increasing over the past decade, particularly among men who have sex with men. In 2019, there were over 130,000 reported cases of syphilis in the United States, with over 60% of these cases occurring among gay and bisexual men.

Syphilis can have a significant impact on public health, as it can lead to numerous complications if left untreated. These complications include blindness, deafness, neurological problems, and even death.

The Importance of Getting Tested for Syphilis

Getting tested for syphilis is crucial, especially if you are sexually active or suspect you may have been exposed to the bacteria. The Centers for Disease Control and Prevention (CDC) recommends that sexually active individuals get screened at least once a year for syphilis and other STIs, even if no symptoms are present.

Testing for syphilis typically involves a blood test, which can detect the presence of antibodies to the bacteria. If the test is positive, antibiotics are typically prescribed to treat the infection. It is essential to complete the full course of antibiotics, even if symptoms have already disappeared.

Preventing Syphilis and Other Sexually Transmitted Infections

Preventing syphilis and other sexually transmitted infections (STIs) involves taking precautions to reduce the risk of transmission. These include:

Practice safe sex. Use condoms or dental dams during sexual activity to protect against contact with bodily fluids.

Limit sexual partners. Reducing the number of sexual partners can also reduce the risk of contracting STIs, including syphilis.

Get vaccinated against other diseases that increase the risk of STIs. Getting vaccinated against hepatitis B or human papillomavirus (HPV) can also reduce the risk of contracting syphilis or other STIs.


Syphilis is a highly prevalent sexually transmitted infection that can cause severe complications if left untreated. Anyone who is sexually active can contract syphilis, and certain populations may be more at risk. Early diagnosis and treatment are crucial in preventing the spread of the disease and reducing the risk of complications. Taking preventative measures, such as practicing safe sex, limiting sexual partners, and getting vaccinated, can also help reduce the risk of syphilis and other STIs. Remember to get tested regularly and seek medical attention if you believe you may have contracted syphilis or any other STIs.
