context_page_description: Meningeal syphilis is a chronic form of syphilis infection that affects the central nervous system. Treponema pallidum, a spirochate bacterium, is the main cause of syphilis, which spreads drastically throughout the body and can infect all its systems if not treated appropriately. Treponema pallidum is the main cause of the onset of meningeal syphilis and other treponemal diseases, and it consists of a cytoplasmic and outer membrane that can cause a diverse array of diseases in the central nervous system and brain.
  Early symptomatic neurosyphilis is the onset of meningeal syphilis. The symptoms arise as a result of inflamed meninges, which eventually lead up to signs of meningitis.
  Treponema pallidum invades the nervous system within three to eighteen months after the primary infection. The initial series of events is asymptomatic meningitis, which can remain in the human body system and produce more damage within the body. Every form of neurosyphilis has meningitis as a component; however, every case differs in severity. The individual is infected with syphilis through a gram negative bacteria that only humans can obtain.
context_section_description: The secondary stages of syphilis persists to be more dangerous to the systems of the human body. The disseminated disease can cause constitutional symptoms and condylomata lata. Many treponemes are present in chancres in the primary stage; however, condylomata lata is usually present in the secondary stage. The pathogen can spread through blood, which can infect the vessels in the body. The infection of the heart, muscles, and vessels in the body can lead to meningovascular syphilis. Generally, rashes may start developing on the hands and soles of the feet, and it can spread to various parts of skin on the body. Other symptoms may include sore throat, headache, joint pain, fever, and patches of hair loss. As in stage one, lesions may start to form on the body, but in this stage in particular, lesions are found in mucous membranes of the mouth, throat, bones, and internal organs. Also common with stage one, the symptoms and signs of secondary syphilis will go away with or without treatment and medication. The diagnosis includes serology nonspecific and specific, both positive. The secondary stage is however highly infectious because the bacteria is spreading drastically throughout the body.
