Types of sexually transmitted Infection (STIs) diseases and symptoms


Gonorrhoea is a sexually transmitted disease that affects both men and women in the age group of 15 to 24 years. It is caused by the bacteria known as Neisseria Gonorrhoeae and may infect the cervix, genitals, rectum, throat and urethra. Symptoms include unusual discharge, burning sensation when urinating, unusual bleeding or spotting as well as pain or inflamation of the genitals. Gonorrhoea can also affect the throat when the infection has been contracted through oral sex. You can catch gonorrhoea when you have anal, oral or vaginal sex with someone else suffering from an infection. It can be treated with antibiotics.


Syphilis is a sexually transmitted disease caused by bacteria called Treponema pallidum. It occurs when you have intercourse with someone who has already been infected. The early sign of the disease is a small and painless sore - known as chancre that appears on the rectum, inside your mouth on your sexual organs. It can be treated with antibiotics.


Chlamydia is a sexually transmitted infection that can be transmitted from one person to another during unprotected sex. It is caused by the bacteria known as bacterium Chlamydia trachomatis passed between people by oral, vaginal or anal sex. If you are experiencing symptoms of this disease, then you may have abdominal pain, fever and abnormal discharge of the vagina or penis. It can be treated with antibiotics.

Genital Herpes 

Genital herpes is a sexually transmitted disease caused by herpes simplex virus (HSV). It may pass from one person to another during anal or vaginal intercourse and oral sex. Pregnant women with genital herpes during pregnancy may pass the infection to their new-born baby thus, causing life-threatening neonatal HSV. Symptoms can be managed with anivirals, however there is no complete cure.


HIV or human immunodeficiency virus attacks your immune system and weakens your chance of fighting against disease. It occurs when you have unprotected intercourse with someone infected with the HIV virus. It can be passed by sharing infected needles or other injecting equipment, HIV-positive mother to her baby during pregnancy, child birth and breastfeeding. AIDS is the syndrome developed during the final stage of HIV when your body cannot fight life-threatening infections. There is no cure for HIV, however treatment is available and getting better every year. 

Human Papillomavirus (HPV)

Human Papillomavirus is the most common sexually transmitted infection or STI.  If you have vaginal, oral or anal sex with someone who already has this virus, then you too are exposed to HPV.  Some areas of the body where HPV may infect are – cervix, penis, head, neck, vagina, mouth and vulva. As with herpes, the viral infection can be managed with medication, but there is no cure.

Bacterial Vaginosis

Bacterial vaginosis or BV is a vaginal condition that occurs with a pungent and unpleasant smell. If you are having BV, your discharge may become grey or white and turn thin or watery. Serious complications may take place at the time of pregnancy and there are also chances of its reoccurrence. It can be treated with antibiotics. 


Trichomoniasis is a common sexually transmitted disease caused by a protozoan parasite known as Trichomonas vaginalis (TV). Men suffering from this disease may have irritation in their penis, discharge from penis and burning after ejaculation or with urination. For women, it may cause a foul-odour vaginal discharge, painful urination and genital itching. It can be treated with antibiotics.

Viral Hepatitis

Viral hepatitis is a liver disease caused by different hepatitis viruses like A, B, C, D and E. You may get this disease by eating food or drinking water infected with stool from one person with the virus and by anal or oral contact. Symptoms include – muscle ache, loss of appetite, nausea, headache, fever, vomiting, diarrhoea, stomach pain and dark-coloured urine. 


Some Common FAQs on Sexual Health


What is a Sexual Health or GUM Clinic?

If you need to be treated or tested for a sexually transmitted infection (an STI) the process will be straightforward and all of your details will always be kept confidential. Another thing you need to know, is that most infections of this type can be cured. Genitourinary medicine clinic known as a GUM clinic or a clinic specialising in sexual health will be able to provide all the necessary tests and the treatment for most STI’s.

What happens during a Sexual Health appointment?

When you reach the sexual health clinic, you will at first have a close discussion with the experts about your concerns. After this you will be asked about your sexual activity and other necessary information related to your health. It is advised to be honest with your doctor so that you may help them carry out the process in the most efficient manner. You will get a chance to talk about any test results with the qualified and experienced sexual health doctors.

Most of the STIs, namely gonorrhoea and chlamydia, can be cured with antibiotics. However, viral infections, like herpes, can be treated and managed to reduce their symptoms and restrict further transmission.

How Long Until I Get My Results?

Some sexually transmitted infections such as HIV, hepatitis and syphilis require a blood sample to be taken from the arm of the individual who needs to conduct the test. The result will normally take about one week. All sex partners should undergo necessary testing even if the result shows no infection, and should abstain from intercourse until results are received.

Can I Get Tested Whilst On My Period?

Normally you will be seen within a week for a swab if an STI is suspected. For females who need to have diagnostic swabs then it is better that they are not having a period when they are being tested.

What does a Test for an STI Entail?

To test for STIs, samples need to be taken from your body. That might mean taking a swab from the mouth as in the rapid HIV test, from vaginal fluids, from the tip of the penis if a urethral swab test is needed, or from blood or urine.

What Questions Will I Be Asked At The Sexual Health Or Gum Clinic Before Std Testing?

The staff in the STD testing clinic will never judge you and will keep everything you say confidential. The questions they ask are to ensure that they get you diagnosed and treated as fast as possible for the relevant STIs.

What is the Best Way to Protect against STIs?

The best way to protect against contracting or passing on an infection is to use a condom each and every time you have sex. You should always remember that having an STI once does not mean that you will be immune in the future; it will be possible to get the same infection again. No one wants to think they have an STI but getting treatment from a renowned STD testing clinic early can give the best chance of a fast cure. Practicing safe sex is always going to be the best way to ensure that you do not contract an STI.
