How are the organs in body affected by syphilis?

Syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum, can affect multiple organs and systems in the body if left untreated. The progression of syphilis occurs in stages, and the effects on different organs vary depending on the stage of the infection. Here's an overview:

Primary Syphilis:

- Skin and mucous membranes: The initial symptom of syphilis is usually a painless sore or chancre that develops at the site of infection, often the genitals, rectum, or mouth.

Secondary Syphilis:

- Skin: A rash typically appears on the trunk, limbs, and palms of the hands, accompanied by flu-like symptoms such as fever, headache, sore throat, and swollen lymph nodes.

- Mucous membranes: Sores or lesions can develop in the mouth, throat, and genitals.

- Eyes: Inflammation of the eye (iritis or uveitis) can occur, leading to blurred vision or eye pain.

- Neurological involvement: Headaches, dizziness, and meningitis are possible symptoms.

Latent Syphilis:

- During the latent stage, which can last for years, there may be no noticeable symptoms.

Tertiary Syphilis:

- Cardiovascular system: Aortic aneurysm, a bulging of the aorta, is a severe complication that can occur.

- Neurological system: Neurosyphilis can develop, affecting the brain, spinal cord, and nerves, leading to various neurological issues such as stroke-like symptoms, dementia, and psychiatric disturbances.

- Eyes: Severe inflammation and scarring may cause vision impairment or even blindness.

- Musculoskeletal system: Painful joints and bone damage can occur.

It's important to note that early diagnosis and treatment of syphilis are crucial to prevent severe complications and long-term damage to organs.適切な性教育、定期的な検査、感染が疑われる場合の専門医への相談が、梅毒の感染リスクと重症化のリスクを下げるため、非常に重要になります。
