Syphilis infections can be one of three stages, primary, secondary, or tertiary depending on how long a person has been infected with syphilis.
Primary syphilis is generally associated with one or more sores (ulcers) around the place of infection (i.e. genitals, cervix, mouth, anus).
Symptoms of secondary syphilis include: skin rash, swollen lymph nodes, and a fever. Often primary and secondary symptoms are mild and may go unnoticed.
Tertiary (latent) syphilis often occurs many years after the initial untreated infection. Symptoms can be severe, these include damage to the heart, eyes, nerves, brain, liver, spinal cord, bones, birth related problems, and can result in fatality.
Resistance and treatment
Syphilis can be treated with an injection of benzathine penicillin. The length of antibiotic treatment depends on the extent of the infection (i.e. primary, secondary or tertiary).
Treatment of syphilis can cure the infection; however, damage associated with the infection many not be cured (e.g. skin rash, damage to organs etc.).
