What are the main transmission routes of sexually transmitted diseases? Classification and transmission routes of sexually transmitted disease symptoms

The World Health Organization (WHO) categorizes sexually transmitted diseases into four levels:

First grade sexually transmitted diseases: AIDS.

Secondary sexually transmitted diseases: syphilis, gonorrhea, soft ptosis, sexually transmitted lymphogranuloma, inguinal granuloma, non gonococcal urethritis, sexually transmitted chlamydia disease, urogenital mycoplasma disease, trichomonas vaginitis, bacterial vaginitis, sexually transmitted vaginitis, and sexually transmitted pelvic inflammatory disease.

Fourth grade sexually transmitted diseases: pear shaped flagellate disease, campylobacter disease, amoebiasis, salmonellosis, shigellosis, hepatitis A.

Route of transmission

Usually, there are five main modes of transmission of sexually transmitted diseases:

(1) Direct contact with infection.

(2) Indirect contact infection.

(3) Placental birth canal infection.

(4) Iatrogenic transmission.

(5) Contact transmission in daily life.

According to statistics, over 90% of sexually transmitted diseases are directly transmitted through sexual intercourse, so the transmission of sexually transmitted diseases is mainly through sexual contact.
