Sexually transmitted infections (STIs) are a significant public health concern, affecting millions of individuals worldwide.

What is a Sexually Transmitted Infection (STI)?

A sexually transmitted infection (STI) is an infection that is primarily spread through sexual contact, including vaginal, anal, and oral intercourse. More than 1 million curable sexually transmitted infections (STIs) are acquired every day worldwide in people 15–49 years old, the majority of which are asymptomatic.


STIs are caused by bacteria, viruses, or parasites and can affect various parts of the body, not just the reproductive organs. Common STIs include chlamydia, gonorrhoea, syphilis, herpes, HIV, and human papillomavirus (HPV). Symptoms can range from mild to severe, and some STIs may not present any symptoms at all, making regular testing crucial. If left untreated, STIs can lead to serious health complications, including infertility, chronic pain, and increased risk of other infections.

What are STI Symptoms?

Sexually transmitted infections (STIs) can present a wide range of symptoms, or sometimes none at all, making it essential to be aware of the potential signs and get tested regularly. Here are some common symptoms associated with STIs:

  • Unusual Discharge: Both men and women may notice a change in the colour, consistency, or smell of their genital discharge. For example, chlamydia and gonorrhoea often cause a yellow or green discharge.

  • Itching or Irritation: Persistent itching, irritation, or redness in the genital region can be a sign of an STI such as trichomoniasis or pubic lice.

  • Sores or Blisters: Painful or painless sores, blisters, or ulcers around the genital or oral areas are common symptoms of herpes and syphilis.

  • Pain During Urination or Sexual Intercourse: Experiencing pain or a burning sensation while urinating or during sexual intercourse can indicate infections like gonorrhoea, chlamydia, or urinary tract infections linked to STIs.

  • Swollen Lymph Nodes, Fever, and Aches: These systemic symptoms can accompany infections such as HIV or syphilis, indicating that the infection might be spreading beyond the initial site.


Recognising these symptoms early and seeking medical advice promptly can help prevent complications and the spread of the infection to others. Regular testing, even in the absence of symptoms, is vital to maintaining sexual health and well-being.

What Are the First Signs of an STI?

Recognising the early signs of a sexually transmitted infection (STI) is crucial for timely diagnosis and treatment. Early symptoms can vary depending on the specific infection, as seen above.


Incubation Periods and Asymptomatic Infections


  • Incubation Periods: The time it takes for symptoms to appear can vary. For example, symptoms of gonorrhoea can appear within 1-14 days, while syphilis symptoms might take 10-90 days to manifest and chlamydia can take 7-21 days. The time it takes for symptoms to appear is known as the ‘incubation period’.

  • Asymptomatic InfectionsMany STIs can be asymptomatic, meaning they do not show symptoms initially. Regular testing is crucial as individuals can still transmit the infection even if they do not exhibit symptoms.

Can STIs Go Away on Their Own?

Whether STIs resolve without treatment depends on the specific infection. Bacterial STIs such as chlamydia, gonorrhoea, and syphilis do not go away on their own. While symptoms might temporarily subside, the infection remains in the body and can cause serious complications if not treated.


Viral STIs such as genital herpes, viral hepatitis B and HPV are generally not curable, but their symptoms can be managed with medication.


Parasitic infections such as trichomoniasis can be cured with antibiotics. However, reinfection is possible, making regular treatment of all sexual partners essential to prevent recurrence.


What Happens if an STI is Left Untreated?


Even if symptoms of an STI disappear, the infection can still cause significant long-term health problems. Untreated STIs can lead to:

  • Infertility
  • Chronic pelvic pain
  • Increased risk of other STIs
  • Organ damage and serious systemic issues

For these reasons, regular testing and prompt treatment are crucial. STIs require appropriate medical interventions to prevent severe health complications and to stop the spread of infections to others.
