In the clinic, 3/4 of the syphilis patients are recessive syphilis, no symptoms on the body surface.” Yesterday, the director of the Department of Dermatology of the Second Hospital of Zhejiang Province, Laolimin experts sitting in the clinic, just happened to encounter several more cases of recessive syphilis patients. Last year, the dermatology department of ZJII reported 507 cases of syphilis to the CDC (including pre-operative examinations), including 186 cases of occult syphilis, these people usually do not see obvious symptoms, and are mostly found after blood donation, routine examination before surgery, pregnancy tests, artificial insemination, and repeated abortions. “Occult syphilis, also called ‘latent syphilis’, manifests itself in patients without clinical symptoms, but positive for syphilis seropositivity. ”What to do, I can’t get a health certificate, the boss won’t let me do it. I can’t do anything else but boil vegetables, I’m worried to death.” To the labor democracy appointment, 27-year-old Zhang Heng (a pseudonym) kept complaining. Zhang Heng is not yet married, is a chef, usually often online dating. Recently just to work in the hotel, need to do health certificate. When he went to the hospital, the syphilis spirochete virus was actually positive, and strangely enough, he had no symptoms at all. ”He is already a second stage latent syphilis, through the body’s immune response, killing some spirochetes, so the level of physical reaction does not seem high.” Laurie Min said. “Earlier, the most people had gonorrhea, then more condyloma acuminata, and later by genital herpes super on. Now it is syphilis that is the most common, ranking first in the incidence of sexually transmitted diseases. The reason for this may be related to the diversification of sexual intercourse, the spread of sexual knowledge, and changes in the body’s immune response.” Laurimin said that syphilis is divided into three stages, and people who come to the hospital for examination usually have reached the second stage. Laurimin explained that in phase I syphilis, patients develop genital ulcers in about 2-4 weeks of sexual contact, but some people go untreated and it will subside in 3-8 weeks and enter the incubation period. 6-8 weeks later, it turns into phase II, which could have shown symptoms of a generalized rash, which is now also in most patients It is not visible. Patients who have not been treated for more than 2 years may have entered stage III, or advanced syphilis. Once symptoms appear, the disease may be irreversible, even with aggressive treatment. ”The most important way to get infected with syphilis is through sexual intercourse. When bodies rub against each other, tiny wounds are created and syphilis spirochetes run in through the wounds.” Laurimin said the public toilet, which people worry about, is unlikely to transmit syphilis. ”Whether you have syphilis, you can observe whether there are ulcers on the genitals, usually the ulcers caused by syphilis are not painful or itchy.” Laurimin said that special attention should be paid to the palms of the hands and feet, if a brick-red rash appears, be sure to check whether you have been suffering from syphilis. Very often, syphilis can easily be misdiagnosed as pityriasis rosea. Of course, if there are repeated miscarriages and baldness, you should also be alert to whether syphilis is to blame.
