10 Common Sexually Transmitted Infections

By STD Concern

They are classified as STD (Sexually Transmitted Diseases) because they can be spread through sexual activity, also referred to as STI (Sexually Transmitted Infections), these infections may be dangerous if left untreated. They don't only affect your current physical health but can also hinder your future fertility and sexual virility.

List in infection type order.

Bacterial Infections

1Chlamydia 

It is a highly contagious STD (Sexually Transmitted Disease). It is a bacterial infection called "chlamydia trachomatis" and can be treated and cured with antibiotics. It's a very common STI, especially amongst 14-24 year old's.

2Gonorrhea 

Formally nicknamed "the Clap", gonorrhea is another bacterial infection that's spread through semen and vaginal fluids. It's caused by a bacterium called "Neisseria gonorrhoeae". This STI can also be successfully treated with antibiotics.

3Syphilis 

The bacteria "Treponema Pallidum" causes this disease, which occurs in several phases. The stages of syphilis include primary, secondary, latent, and tertiary. It is a treatable but highly contagious sexually transmitted disease or STD. 

Parasitic Infections

4Trichomoniasis 

It is a sexually transmitted disease or STD. It is sometimes referred to as Trich or Trichomonas, and it is caused by a parasite known as "Trichomonas Vaginalis." This parasite is commonly found in sexual fluids, including vaginal, pre cum, and semen.

Other. Pubic Lice 

Also known as Genital Crabs or STD Crabs, are a relatively common - and easily treated - sexually transmitted disease. What sets pubic lice apart from the rest of the sexually transmitted diseases is the fact that they aren't always transmitted sexually.

Viral Infections

5Hepatitis A 

Is a very contagious infection that attacks the liver, leading to tissue inflammation and decreased organ's function. People often contract hepatitis A from sexual contact, particularly oral sex, or from ingesting contaminated water or food.

6Hepatitis B 

It is a kind of viral infection that attacks the liver and can lead to life-long disability, cancer, or even death. It is transmitted through contact with blood or other body fluids that contain the virus. A vaccine against Hepatitis B has been available since 1982 and is 95% effective.

7Hepatitis C 

It is another liver disease, which is often symptomless or its effects are very mild. An infected person's body is frequently able to fight off the virus, leading to a complete recovery. However, like hepatitis B, there is also the possibility of this illness becoming chronic.

8. Herpes 

The 2 Types (strains) of herpes caused by the "Herpes Simplex Virus" (HSV) are Oral (HSV-1) and Genital (HSV-2). Symptoms will start showing up 4 days after exposure & last up to 4 weeks. Once you’re infected the following outbreaks tend to be milder.

9. HIV 

The Human Immunodeficiency Virus is the virus responsible for AIDS. HIV does not directly cause death, but damages the immune system to such an extent that other infections, even common infections, can become fatal.

10. HPV 

The Human Papillomavirus is the name for a group of viruses that includes more than a 100 strains or types, of which around 40 can be sexually transmitted. Many people who contract HPV are unaware of it, as the virus often produces no symptoms. Others may develop genital warts or in rare cases, in their throat. 


To avoid being infected practice safe sex which includes using condoms and not engaging in sex with an infected person. If you have any of these symptoms you should be tested ASAP (as soon as possible), and sexual partner(s) be contacted.


In order to receive proper treatment, "testing is required".
