In recent decades, with the opening of people’s sexuality, the incidence of STDs in China has been on the rise year by year. The common STDs include gonorrhea, non-gonococcal urethritis, condyloma acuminata, genital herpes, syphilis, soft chancre, and lymphogranuloma venereum, among which gonorrhea, syphilis, genital herpes, and condyloma acuminata are in the top positions. Non-use of contraceptives, extramarital sex, unsafe sex and diversification of sexual behavior are all risk factors for infection, but lack of knowledge about sex and neglect of sexual health are the main reasons for the increase of infection. The susceptible groups of STD are mainly sex workers, homosexuals, clandestine prostitutes and clients, reeducation through labor and drug addicts, maternity, entertainment venues, etc. In addition, some high-end entertainment venues, barber stores in urban villages, massage rooms, etc. are also high-risk places for STD infection. 1, the mode of transmission of STDs 1, sexual transmission: mainly including kissing, touching, hugging, sexual intercourse, etc., sexual intercourse is the main means of transmission. 2, contact transmission: through contaminated towels, bath tubs, clothes, toilets, underwear, commode and other supplies spread. 3, blood-borne transmission: infection by receiving blood and organs or tissues contaminated with pathogens. 4.Mother-to-child transmission: Infection of the fetus or newborn during pregnancy or delivery, such as congenital syphilis, neonatal gonorrhea or chlamydial conjunctivitis, AIDS, herpes virus infection or cytomegalovirus infection, etc. 5, medical transmission: the use of unsterilized or poorly sterilized medical equipment and be infected. Although there are many ways of STD infection, but most of them are infected through unclean sexual behavior, so establish a healthy sexual concept, consciously eliminate all unsafe sex is the most important factor to prevent STD infection and injury. At the same time, when having a normal, healthy sex life, be sure to use a reliable quality condom, which can effectively reduce the risk of transmission of AIDS and other STDs. So what can you do to stay away from STDs? The following points should be done: 1. Make sure that your sexual partner does not have STDs. 2. Condoms, vaginal diaphragms, etc. should be used during every cunnilingus, anal sex and oral sex, which will help protect you from STDs. But condoms are not 100% insurance, there is about 10% or more failure rate. 3, keep your genital organs clean and hygienic, do not sleep in the same bed with STD patients, do not share towels, clothing, dishes, not to mention razors and other utensils. When you go out, pay attention to the choice of good sanitary conditions of hotels, restaurants, bathrooms, etc. 4, do not take drugs, do not share syringes or needles with others, urgent blood transfusion, to confirm the safety of blood products. 5.Know the symptoms of sexually transmitted diseases, if you find similar symptoms, you should immediately seek medical attention. 6.Prevent infection of medical origin. But the ordinary contact in daily life is not infected with STDs, such as shaking hands, eating together, sharing the same sanitary equipment, etc. will not be infected with STDs. The clinical symptoms of STDs are characterized by the presence of herpes, ulcers, warts, skin, palms, feet rashes and other symptoms on the genital area of men and women, but there are some people who do not have symptoms, so people who have a history of unclean intercourse without symptoms do not necessarily not have STDs, especially women. Therefore, people who have a history of unclean sexual intercourse should do the relevant tests. STDs mainly cause damage to the genitourinary organs of patients, such as: gonococcal urethritis, epididymitis, prostatitis, etc.; syphilis can also cause bone, cardiovascular, nerve damage, and even life-threatening; STDs in women can cause stillbirth or infertility; through mother-to-child transmission, directly endangering the health of future generations; some STDs can cause inflammation of the genitals, ulcers, increasing the risk of HIV infection in patients. Generally speaking, the symptoms of STDs are different between men and women: 1, more men with acute onset, more women with chronic infection and more carriers. 2, male clinical performance is more typical, easy to diagnose, female performance is more atypical, symptoms are not obvious, easy to misdiagnosis, missed diagnosis. Men are easy to find the change of genital organs by themselves, women are more difficult. 3, and STD patients with unprotected sexual contact, women are more likely to be infected than men. 4, women can transmit STD to the next generation through the placenta, birth canal, breast milk. It is worth noting that women are more likely to contract STDs than men, and young women have a greater chance of infection. This is because the secretions from the vaginal wall during sexual intercourse provide the conditions for the growth of viruses and bacteria. So just because there aren’t any signs of STDs doesn’t mean you should forget about safe sex! Remember, you or your partner may have contracted an STD without your knowledge, and your failure to take any safety measures during sex will cause the STD to continue to be transmitted over and over again. Third, the clinical symptoms of common STDs 1, gonorrhea: gonorrhea is Neisseria gonorrhoeae (referred to as gonococcus) caused by the genitourinary system septic infection as the main manifestation of sexually transmitted diseases. Gonococcus is a gram-negative diplococcus, which is not easy to survive away from the human body and is easily killed by general disinfectants. Gonorrhea mostly occurs in young men and women who are sexually active. The main mode of transmission is impure sexual intercourse, and indirect transmission can also be caused by objects contaminated with gonococcal secretions. The incubation period of acute gonorrhea in men is usually 2-10 days, with an average of 3-5 days. The symptoms include burning and itching at the urethra, painful urination, frequent urination, large amounts of purulent discharge, gonorrhea or blood in the urethra, and pus crusting at the urethra in the morning. It is accompanied by mild to severe systemic symptoms. Men with chronic gonorrhea generally have no obvious symptoms, but when the body resistance is low, such as excessive fatigue, alcohol consumption, sexual intercourse, that is, the symptoms of urethritis, but lighter than the acute inflammation, urethral discharge less and thin, only in the morning in the urethral orifice with pus crust adhesion. The actual UTI is a very good way to get the most out of the UTI. 2, non-gonococcal urethritis: non-gonococcal urethritis is a sexually transmitted disease caused by Chlamydia trachomatis and mycoplasma, 30% to 50% of non-gonococcal urethritis is related to Chlamydia trachomatis, 20% to 30% is Mycoplasma solani infection, 10% is caused by microorganisms such as Trichomonas vaginalis, Candida albicans, herpes simplex virus, Mycoplasma genitalium, adenovirus and bacillus, Chlamydia and Mycoplasma Chlamydia and mycoplasma are weakly resistant to the external environment and can be killed by heating at 56°C for 5 to 10 minutes. Commonly used disinfectants such as formalin, Lysol and carbolic acid also kill them very easily. Clinically, there are manifestations of urethritis, but no gonococcus can be detected in the secretions and no gonococcus growth in bacterial culture. Men show urinary prickling, painful urination, redness and swelling of the urethral orifice, and thin discharge; female patients show increased leucorrhea and painful urination, and symptoms such as lumbar and abdominal pain if pelvic inflammatory disease is caused. 3, condyloma acuminata: condyloma acuminata is caused by human papillomavirus (HPV) infection to the anal genital area proliferative damage as the main performance of sexually transmitted diseases. Most of them occur in young people aged 18 to 50. The disease develops after an incubation period of about half a month to 8 months, with an average of 3 months. In males, it is mostly found in the foreskin, ligament, coronal sulcus, glans, urethral orifice, penile body, perineum, rectum and scrotum, and in females, it is mostly found in the labia majora and minora, posterior union, vestibule, clitoris, cervix and perineum. Occasionally, it is seen in areas other than the pubic and perianal areas, such as the axilla, umbilicus, oral cavity, breasts, and between the toes. Vaginitis in women and male circumcision are contributing factors to the development of acromegaly. The damage is initially small, light red papules, then gradually increasing, single or clustered distribution, moist and soft, the surface is uneven, papilla-like, coronary or cauliflower-like protrusion, red or dirty gray, the root often has a tip, and prone to vesicles oozing, easy to touch bleeding. The lesions often have purulent secretions accumulated between the cracks, resulting in a foul odor, and can cause secondary infection due to scratching. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. The actual fact is that you can find a lot of people who are not able to get a good deal of money from the internet. 4, genital herpes: genital herpes is a sexually transmitted disease caused by herpes simplex virus (HSV), mainly HSV-2 type, a few for HSV-1 type. It is one of the common STDs. Genital herpes can recur and has a significant impact on the health and psychological well-being of the patient. It can also infect newborns through the placenta and birth canal, leading to congenital infection in newborns. It usually develops 2 to 10 days after infection, and can develop in individual patients after several months or a year. It often occurs in the foreskin, glans and coronal sulcus of the penis in men and in the labia, clitoris or cervix of women. The clinical manifestations of the disease are mostly in women. The clinical manifestations of the disease include conscious burning in the pubic area, the appearance of multiple small papules or blisters in the genital area, which can then become pustules or ulcers, accompanied by poor urination, fever, headache, arthralgia, and swollen lymph nodes. 5, syphilis: syphilis is a chronic, systemic sexually transmitted disease caused by the pale (syphilis) spirochete. Mainly through the sexual route of transmission, divided into one, two, three syphilis. Phase I syphilis can be manifested in the genitalia as sclerosis, the preferred site for the penis, glans, coronal sulcus, foreskin, urethral orifice; large and small labia, clitoris, cervix; anus, anal canal, etc., also seen in the lips, tongue, breast, etc. If there are many painless rose-colored red spots on the palms of the body should be highly suspicious of second-stage syphilis, second-stage syphilis lesions are diverse, some like psoriasis, some like pityriasis rosea, etc. When there is the above painless skin damage, you should seek medical attention as soon as possible. 1/3 of the untreated dominant syphilis infection occurs in the third stage of syphilis, manifested as nodular syphilis rash, gum-like swelling, subcutaneous fibrous nodules and other manifestations. Fourth, if infected with STDs, the following matters should be noted during treatment: 1, if unsafe sex, STD symptoms should be promptly to the regular medical institutions for examination and treatment, early detection, early diagnosis, early treatment, to prevent the occurrence of complications and sequelae. 2, the whole standard full treatment is very important, should follow the doctor’s instructions to take drugs, their own stop, increase or decrease the drug or find a travel doctor treatment will have adverse consequences. 3, during treatment problems should be timely consultation with the doctor, regular review until cure. 4, during the treatment period should not have sex, the patient’s spouse or sexual partner should also go to the hospital for examination or treatment.
