What is STD?

STD is an abbreviation for “sexually transmitted disease”.

  • Sexually – or sex is having any part of the penis inserted into the vagina, anus, or mouth of another person. Or cunnilingus.
  • Transmitted – pass on from one person to another
  • Disease – is an infection which is symptomatic.

Therefore a STD is “a symptomatic infection which is passed on from one person to another by having any part of the penis inserted into the vagina, anus, or mouth of another person, or cunnilingus.”

What are the common STDs?

They are caused by viruses, bacteria, and parasites:

  1. HPV infection
  2. Genital herpes
  3. Chlamydia
  4. Gonorrhea
  5. Syphilis
  6. HIV infection

HPV infection is caused by a virus, called human papillomavirus or HPV. After infection, 3 to 6 months later, at the points of sexual skin contact, like the penis, pubic area, vagina, anus and mouth, there may appear growths called genital warts. Of the many types of HPV, some may cause cancer of the areas affected. The cancer risk is highest for the female cervix, when compared to other areas.

Genital herpes is caused by a virus, called herpes simplex virus or HSV. After infection, 1 day to 2 weeks later, at the points of sexual skin contact, like the penis, pubic area, vagina, anus, and mouth, there may appear blisters and ulcers.

Chlamydia is caused by a bacterium called Chlamydia trachomatis. After infection, 1 to 3 weeks later, while urinating, there may be an irritation. Also, there may be a grey to green discharge.

Gonorrhea is caused by a bacterium called Neisseria gonorrhoeae. After infection, 1 day to 2 weeks later, while urinating, it is usually painful. Also, there is usually a thick yellow discharge.

Syphilis is caused by a bacterium called Treponema pallidum. After infection, 9 to 90 days later, at the point of sexual skin contact, like the penis, vagina, anus and mouth, there may appear a chancre, which is a painless ulcer.

HIV infection is caused by a virus, called human immunodeficiency virus or HIV. After infection, 2 to 4 weeks later, there may be symptoms of acute HIV infection. Which are usually fever, malaise (general discomfort), muscle pain (myalgia), rash, headache, night sweats, sore throat, swollen lymph nodes, joint pain, and blocked nose.
