Caused by a bacterium, syphilis is one of the most widespread sexually-transmitted diseases today. It can strike men, women, kids, teens, and adults. Syphilis is made up of different stages. Each stage features various signs and symptoms that range from mild to very severe.

Primary Stage

- This starts the moment the syphilis bacterium infects a person. It may last for 10 to 30 days since initial exposure to the infection. Its most common symptoms are a small, round, painless sore (known as chancre) and swollen lymph nodes.

Secondary Stage

- This stage kicks in about two to ten weeks since the first appearance of a chancre. Its symptoms include aching and soreness all over the body, fever, fatigue, and rashes on the palms of the hand and soles of the feet.

Latent Stage

- No new symptom appears during this stage.

Tertiary Stage

- This is the final stage of syphilis and features the following symptoms: poor muscle coordination, deafness, numbness, visual problems, paralysis, meningitis, inflammation of the aorta, and aneurysm.
