It is more accurate to say that syphilis is contagious, and an infected person may develop syphilitic meningitis as the disease progresses. Syphilitic meningitis is an inflammation of the brain caused by the invasion of the syphilis spirochete, and it is important to treat the disease when it is recognized. Syphilis is mainly sexually transmitted, the pathogen is syphilis spirochete, when the patient’s semen or vaginal secretions contain a large number of syphilis spirochete, through the broken skin and mucous membranes will cause infection, so syphilis is infectious. After the syphilis spirochete enters the body, it will invade the central nervous system through the blood circulation, thus causing the appearance of syphilitic meningitis, which will be accompanied by fever, headache, loss of appetite and other symptoms. If you suffer from syphilitic meningitis, you should actively carry out the treatment, and usually use drugs to relieve the condition, such as ceftriaxone sodium for injection, penicillin sodium for injection and so on. In the treatment must follow the doctor’s instructions, do not use drugs arbitrarily, and do not modify the treatment method arbitrarily. In the treatment, you should pay attention to the regular review in the hospital, so as to understand the recovery situation. Those who are in close contact with syphilis patients need to pay attention to self-protection, and may be infected by touching the intimate clothing of syphilis patients, kissing and sexual behavior.
