These are the four stages of syphilis and their symptoms:
The Primary Stage
Appearance of a Syphilis Sore
The primary stage is the first stage. It is when the syphilis sore first appears. This sore will eventually ulcerate with an indurated border.
The sore appears where the bacteria entered your body. This usually occurs in the genitals but may also form at other ports of entry. The syphilis sore contains highly infectious bacteria called spirochete Treponema pallidum. The syphilis sore is usually firm, round, and painless.
The sore itself can last up to 3-6 weeks and will disappear whether or not treatment is administered. However, the bacteria will remain long after the sore disappears, so one must still receive treatment to prevent the disease from progressing.
The Secondary Stage
4-10 Weeks After Syphilis Sore
Approximately 25% of people with primary infection will develop the second stage. The secondary stage involves a wide variety of generalized symptoms, and may also include skin rashes, hair loss, gastrointestinal, muscular, renal, and neurological abnormalities.
While the secondary stage can manifest in many ways, the most common symptoms for it are reddish, non-itchy rashes and blemishes that start on your trunk and may completely envelop your body.
These rashes may also become pustular. They are usually accompanied by fluid-filled, wart-like sores in the genitals and buttock areas. These wart-like lesions and rashes are highly contagious and have a high chance of spreading the disease upon contact.
Rashes may also appear in the palms and soles. Whitish erosions may appear on the tongue and other mucosal surfaces as well.
Secondary symptoms may occur such as:
