Patient education regarding the contagious nature of bacterial conjunctivitis and prevention measures:

  • Inform the patient that bacterial conjunctivitis is contagious and can spread to the other eye and to other people.
  • Advise frequent hand washing with soap and water to reduce transmission.
  • Recommend using separate towels and flannels to avoid sharing infectious material.
  • Advise avoiding close contact with others, especially healthcare professionals or childcare providers, as the infection may be contagious for up to 14 days from symptom onset.
  • Explain that most cases are self-limiting and resolve within 5–7 days without treatment, but topical antibiotics may be used if symptoms are severe or do not improve after 3 days.
  • Advise patients to avoid touching or rubbing their eyes to prevent spread.
  • For contact lens wearers, instruct immediate cessation of lens use until all symptoms resolve and emphasize eyelid hygiene with sterile saline or boiled and cooled water.
  • Inform that there is no recommended exclusion period from school or nursery for isolated cases, but local policies may vary.
  • Provide written information and explain red flags that require urgent medical review, such as worsening symptoms or persistence beyond 7 days.
