Introduction
Transmission through sexual contact: This is the primary mode of transmission; over 90% of sexually transmitted infections (STIs) are spread via unprotected or unsafe sexual intercourse. During intercourse, blood vessels become markedly dilated and engorged with blood, increasing susceptibility to friction and minor trauma—creating ideal conditions for pathogens to enter the body. Bloodborne transmission: Asymptomatic individuals in the incubation period may donate blood unknowingly, potentially transmitting STIs through blood transfusions.

In today’s society, a significant portion of the population develops sexually transmitted infections (STIs) due to unhealthy lifestyle habits. So, what are the transmission routes of STIs?

What Are the Transmission Routes of STIs?

Sexual contact transmission: This is the primary route of transmission—over 90% of STIs are spread through unprotected or unsafe sexual activity. During intercourse, blood vessels become markedly dilated and engorged with blood, making the mucosal surfaces more susceptible to friction and microtrauma; pathogens can thus easily enter the body. Bloodborne transmission: If an asymptomatic individual in the incubation period donates blood, recipients of that blood may contract an STI.

Indirect transmission via contaminated objects: Contact with items used by infected individuals—such as toilet seats, bidets, towels, clothing, or bedding—may lead to STI transmission via residual secretions. Therefore, all personal items used by patients should be promptly disinfected to prevent indirect transmission.

Transplacental and perinatal transmission: If a pregnant woman has an STI, the infection may be transmitted to the fetus across the placenta during pregnancy. Additionally, newborns may acquire the infection while passing through an infected birth canal during delivery. Thus, it is strongly recommended that individuals undergo complete treatment for STIs prior to conception to avoid giving birth to an unhealthy baby. In daily life, proper hygiene of the genital area is essential—keep the area clean and dry. Sexual activity should be avoided for a short period to prevent worsening of the condition. We hope this information is helpful to you!

What Are the Symptoms of Sexually Transmitted Infections (STIs) in Men?
Genital ulcers: - Round, cartilage-like hard, painless, solitary ulcers are most likely chancroid (hard chancre). - Soft ulcers with jagged, irregular margins, relatively shallow depth, associated with pain and multiple lesions covered by purulent exudate are most likely soft chancre. - Ulcers evolving from clustered vesicles, soft in consistency and painful, are most likely genital herpes.

Genital warts: - Grayish-white, flat, elevated papules or nodules on the vulva or perianal area, often accompanied by a foul odor—most likely flat condyloma. - Cauliflower-shaped or cockscomb-shaped, pedunculated warts that are light red or grayish-brown—most likely anogenital warts (condyloma acuminatum). - Dome-shaped papules where a cheesy, curd-like material can be expressed upon puncturing the apex—suggestive of molluscum contagiosum.

What are sexually transmitted infections (STIs)?
Sexually transmitted infections (STIs) include condyloma acuminatum, gonorrhea, syphilis, acquired immunodeficiency syndrome (AIDS), and trichomoniasis. 1. Condyloma acuminatum: primarily caused by human papillomavirus (HPV) infection; 2. Gonorrhea: primarily caused by *Neisseria gonorrhoeae* infection; 3. Syphilis: caused by *Treponema pallidum* infection; 4. AIDS: primarily caused by human immunodeficiency virus (HIV) infection; 5. Trichomoniasis: primarily caused by *Trichomonas vaginalis* infection.

How is genital herpes caused?
Genital herpes is caused by infection with the herpes simplex virus (HSV) and is primarily transmitted through sexual contact. The most common manifestation is genital herpes: in males, lesions typically occur on the prepuce, glans penis, and shaft of the penis, whereas in females, they commonly affect the labia and clitoris. In homosexual individuals, lesions frequently involve the anus and rectum. Affected areas are usually accompanied by pruritus and pain. Antiviral therapy—typically oral acyclovir—is generally required.

Which sexually transmitted infections cause bumps on the body?
Common sexually transmitted infections (STIs) that present with skin nodules or bumps include HIV/AIDS, non-gonococcal urethritis, genital herpes, condyloma acuminatum (genital warts), and chancroid. Urticaria, a dermatological condition, manifests as an allergic skin reaction resulting from immune system dysregulation. Management of this condition primarily focuses on antiallergic therapy and alleviation of pruritus and wind-related symptoms. Recommended oral medications include azathioprine hydrochloride tablets and compound glycyrrhizin capsules.

What Is the Risk of Contracting a Sexually Transmitted Infection (STI), and How Can It Be Prevented?
Regarding sexually transmitted infections (STIs), transmission routes are diverse. Patients diagnosed with an STI should abstain from sexual activity to prevent viral transmission to partners—or mutual reinfection—through genital contact, as such behavior significantly hinders effective treatment. Additionally, preventive measures against STIs are strongly recommended. Patients are advised to maintain personal hygiene and moral integrity in daily life, adhere to social norms, avoid illicit drugs, and refrain from seeking care at unlicensed or informal medical facilities solely to save money.

Which sexually transmitted infections cause bumps on the body?
Patients with sexually transmitted infections (STIs) may indeed develop nodules—such as genital warts—but patients with urticaria (hives) may also present with raised skin lesions. Common STIs include HIV/AIDS, non-gonococcal urethritis, genital herpes, anogenital warts (caused by human papillomavirus), and chancroid. Urticaria is an allergic skin disorder resulting from dysregulation of the body’s immune system. Treatment for this condition primarily focuses on antiallergic therapy and alleviating wind-induced itching.
