What is the nature of sexually transmitted diseases? Are all sexually transmitted diseases transmitted through blood?

A sexually transmitted disease is defined as a disease that is transmitted through sexual contact, known as a sexually transmitted disease. Common classical sexually transmitted diseases include: AIDS, syphilis, gonorrhea, chlamydia infection, HPV infection, condyloma acuminatum.

The essence of sexually transmitted diseases is infection in close contact with reproductive organs. Sexual contact, genital organs close contact friction, body fluid exchange, genital organs skin mucous membrane small wound. These wounds increase the chance of pathogen infection.

Treponema pallidum, which causes AIDS and HIV, is present in all bodily fluids of the patient’s body, including blood and semen. During sexual intercourse, viruses and spirals enter the body through tiny wounds and infect each other. Chlamydia and gonococcus mainly infect the columnar epithelium of the reproductive organs, such as the male urethra, the female urethra, or the cervical tubular epithelium. During sexual intercourse, infection of fluid exchange causes local suppuration. Male manifestations of balanopathy, pyuria, frequent urination, pain in urine, hematuria. Women may present with purulent leucorrhea, menstrual disorders, uterine tenderness, abdominal pain, tubal abscess, pyuria, frequent urination, dysuria, and hematuria.

If one vulvar or cervical epithelium is infected, the virus is an epitheliophilic virus and is present only in the epithelial tissue. HPV, sexual intercourse can infect each other, especially if there is mild trauma to the epithelial tissue. HPV infection, high-risk HPV infection can cause cervical, vulvar, anal and penile cancer HPV infection can cause cervical cancer.

Not all sexually transmitted diseases can be simultaneously transmitted through blood

AIDS and syphilis are sexually transmitted diseases and are also blood-borne diseases. If the blood in the transfusion is not clean, infection. At the same time, both diseases can also be transmitted vertically from mother to child. The fetus is infected through the placenta during pregnancy, and the fetus is infected by contact with the mother’s blood during delivery. Gonococci, chlamydia, and HPV are not blood-borne diseases. Gonococci and chlamydia mainly cause local infection and abscess, and rarely cause sepsis. Even if bacteria enter the blood, blood is not donated during severe illness due to severe symptoms. HPV does not enter the bloodstream at all.

The principle of sexual transmission is transmission by close contact, so if you use condoms as a physical barrier, you can prevent the transmission of sexually transmitted diseases.

Blood-borne diseases may not be sexually transmitted. Hepatitis B and C are also blood-borne diseases, but are mainly transmitted through blood transfusions, sharing syringes, dialysis, etc., and can also be transmitted from mother to child, but rarely through sexual transmission.
