1, through sexual transmission: It is mainly transmitted through sexual intercourse or other sexual acts. Male gonorrhea almost always caused by sexual contact, female sexual intercourse gonorrhea may also be a direct infection, may also be infected in other ways. Gonorrhea is a source of infection in patients with sexual contact is the main mode of transmission of gonorrhea, spread fast, and the high rate of infection, the incidence can be 3-5 days after infection. Infection in the crowd to youth.

2. Non-sexual transmission (indirect transmission): this situation is rare, mainly contact with patients with Gonococci secretions or contaminated equipment, such as the stained secretions towels, foot massager cloth, clothing, and even the toilet The toilet ring and so on can be infected, especially women (including young girls), because of their short urethra and reproductive tract, it is susceptible to infection. After suffering from gonorrhea newborns mother's birth canal, the eye may also cause neonatal gonococcal ophthalmia, pregnant women gonorrhea can cause intra-amniotic infection in patients, including fetal infection.

Adults, especially men, gonorrhea 99% -100% are sexually transmitted. At present, with commercial sex workers as the main source of infection. Survey data show that patients in the gonorrhea infection rate of first intercourse for men and women 22% -35%; both men and women are men and easy transmission of infection to women. First intercourse male to female transmission of the infection rate is 50% -90%, female to male transmission of 25% -50% for the rate of infection is proportional with the frequency of sexual intercourse. Infection rate of male and female patients with sexual intercourse an average of 19% -25%, 2 times for 35%, three times for 49%, four times for 57%.

Human beings are the only natural reservoir of Neisseria gonorrhoeae, the main violation of mucous membranes, especially for single-layered columnar epithelium and transitional epithelium of the mucous membrane formed by affinity. Gonococcus infection invaded the former male urethra, female urethra and cervix, etc., due to fimbriae on its surface contains adhesion molecule, and thus adhere to the surface of columnar epithelial cells in reproduction and reproductive Road along the line, through the columnar epithelial cells of the phagocytic role of the inside of the cell reproduction, resulting in cell lysis breakdown of Neisseria gonorrhoeae is ranked accordingly to the cell outside the submucosa. Neisseria gonorrhoeae and gonococcal endotoxin LPS produced by the surface membrane and complement fixation to produce a chemical toxin, can induce aggregation and phagocytosis of neutrophils in acute inflammation caused by localized, there hyperemia, edema, suppuration and pain. When the bacteria enter the urethra gland and the crypt, the pit and the crypt is blocked, the bacteria become a potential primary lesion of chronic gonorrhea.
