What are the characteristics of secondary syphilis infection? How long does syphilis lurk and attack

Phase II syphilis is a chronic systemic infection caused by Treponema pallidum infection, mainly sexual. The manifestations of this disease are extremely complex, and can almost invade various organs throughout the body, causing damage to multiple organs. The second stage syphilis causes skin mucosal damage and Lymphadenopathy. Syphilis is transmitted to the next generation through the placenta, causing congenital syphilis in newborns, which is extremely harmful.

Analysis of the causes of secondary syphilis

Sexual activity is messy and personal hygiene is not valued. Sexual contact is the main Pathogen transmission of syphilis, accounting for more than 95%. The early infectivity of syphilis is the strongest. As the disease progresses, the infectivity decreases, and it is generally believed that the infectivity of sexual contact after more than 4 years of infection is very weak.

Pregnant women with syphilis can transmit it to their fetuses through the placenta, leading to intrauterine infections, which can lead to miscarriage, premature birth, stillbirth, or childbirth. It is generally believed that the earlier the period of syphilis in pregnant women, the greater the chance of fetal infection. Pregnant women with Asymptomatic recessive syphilis are also infectious.

The second stage of syphilis is the transmission of Treponema pallidum through the bloodstream throughout the body, with many small lesions appearing in various organs, affecting the skin, mucous membranes, bones, internal organs, sensory organs, and nervous system. The initial symptoms of the second stage of syphilis are the appearance of hard lower scabies one week after their appearance, and a few months after the lower scabies heal. The second stage of syphilis is the generalized stage of syphilis, where the damaged parts of the skin and mucous membranes contain a large amount of Treponema pallidum, which is highly infectious, Mild damage to organs and tissues, but without treatment, may lead to the development of syphilis in organs, nerves, bones, joints, and other areas in the future

What are the typical symptoms of secondary syphilis

1、 Prodromal symptoms

Patients with secondary syphilis have prodromal symptoms such as slight fever, headache, bone pain, Trigeminal nerve nerve, intercostal Neuralgia, and weakness before the skin rash. Generally lasting for 3-5 days, the prodromal symptoms are mild and often overlooked by patients.

2、 Secondary syphilitic skin lesions

1. Rashes are characterized by mild, widely distributed, dense, and symmetrical symptoms. The main type is ① spotted syphilid, mainly distributed on the inner side of the trunk and proximal limbs, with different sizes. The diameter is about 0.5-2 centimeters, which is circular, and the number is rarely elliptical. Occasionally, the circular color resembles rose red, and is called rose spotted. ② The common type of syphilis rash is papular type. Generally, small papules with a diameter of 2-5 millimeters turn brown after initially appearing copper colored. Generally speaking, the matrix is hard and the surface contains a small amount of scales and other rash types, which have strong infectivity The diagnosis of pustular syphilis is relatively rare. Initially, it appears as a macula, but later it is named after a small pustule on the top of the protrusion, which is widely distributed. This type of patient generally has poor nutrition Pustular syphilid is very rare..
