Lesson notes preview

Read the core explanations from Sexually Transmitted Infections - Gonorrhoea before testing yourself from memory.

• Gonorrhoea might sound like a complicated medical term, but it's actually one of the most common sexually transmitted infections worldwide. Understanding this disease is crucial because it affects millions of people and shows us how bacteria can evolve to resist our treatments.
• A sexually transmitted disease (STD) caused by the bacterium Neisseria gonorrhoeae, characterised by thick yellow or green discharge from reproductive organs and pain during urination.
• The key word here is 'bacterium' - gonorrhoea is caused by a living microorganism, not a virus. This matters because bacterial infections can be treated with antibiotics, though as we'll see, this isn't always straightforward anymore.
• The symptoms of gonorrhoea are quite distinctive, which helps with diagnosis. Both men and women experience similar symptoms, though they may be more noticeable in men.
• The main symptoms are:Thick yellow or green discharge from the vagina or penisPain or burning sensation when urinatingIn some cases, pelvic pain or swollen testicles
• Important: Some people, especially women, may have no symptoms at all. This is dangerous because they can still spread the infection without knowing they have it.
• Gonorrhoea spreads through sexual contact. This means any sexual activity that involves contact between the reproductive organs, mouth, or rectum can transmit the bacteria from an infected person to an uninfected person.
• The bacteria live in the warm, moist environments of the reproductive tract, throat, and rectum. During sexual contact, these bacteria can transfer from one person to another through bodily fluids.
• Trap: Many students think gonorrhoea can spread through toilet seats or sharing towels. This is false - the bacteria cannot survive outside the human body for long enough to spread this way.
• Here's where gonorrhoea becomes a real problem for modern medicine. When antibiotics were first discovered, gonorrhoea was easily cured with penicillin. But the bacteria that cause gonorrhoea have evolved.
