How long has stage II syphilis been infected? What are the symptoms of secondary syphilis

Syphilis is a chronic systemic infection caused by Treponema pallidum infection, mainly through sexual infection. What are the symptoms of the second stage of syphilis? With that in mind, let's look at the following introduction.

Symptoms of secondary syphilis

What are the symptoms of secondary syphilis? Phase II syphilitic rash This is an inflammatory reaction caused by the spread of Treponema pallidum through the blood circulation to the whole body. A few days before the eruption, there may be low fever, headache, sore throat, swollen tonsils, sore joints, anorexia and other precursor symptoms. The size of the rash is 41 times that of rose-pigmented papule or pustular rash, which is widely distributed and symmetrical. The skin of the whole body can erupt, mainly in the palm, part, scrotum, penis, etc. Gray and white flat warts occur at the wrinkled part of the skin or the connecting part of the skin and mucous membrane, such as around the anus, vulva, corner of mouth, armpit, and under the breast. The palms and fingers show flesh red peeling spots. The rash has no conscious symptoms, neither pain nor itching, and can disappear naturally from one month to several months. There is no scar after regression, but the serum reaction is usually positive.

The period from the disappearance of the hard subprickly heat to the appearance of the secondary syphilitic rash is called the second incubation period. The second stage of syphilitic rash generally occurs 3 to 4 weeks after the subdural scabies recede, equivalent to 9 to 12 weeks after infection. Phase II syphilis is the extensive systemic damage caused by Treponema pallidum entering the blood through lymph nodes. In addition to causing skin damage, it can also invade the viscera and nervous system.

After the disappearance of the secondary syphilitic rash, similar lesions occur within 1 to 2 years, which is called the recurrence of the secondary syphilitic rash. Most of them are localized hyperplastic patches, such as verruca plana and psoriasis, which mostly occur on the extended side of the limbs. Regenerative hypodermia can also occur again at the original hypodermic prickly heat of the reproductive organs. The secondary syphilitic rash is moist, and its exudate contains a large amount of Treponema pallidum, which is highly infectious.

Syphilic alopecia is prone to occur in the head, pillow and temporal region, with sparse alopecia and unclear boundary, especially in the form of insect erosion: bone and joint syphilis can cause periostitis and arthritis, and the pain is heavier at night and at rest. Eye syphilis with less pain during the day and during activities can cause iritis, iridocyclitis, choroiditis, optic neuritis, retinitis, etc

Before the eruption of secondary syphilis, some patients (about 50% of women and about 25% of men) had fever, headache, bone and joint pain of varying degrees, swelling of liver, spleen and superficial lymph nodes of the whole body, loss of appetite, and general discomfort. Generally, it will improve in 3-5 days, and patients often do not pay attention or mistakenly think it is other diseases.
