A 6-year-old child presents with acute onset of red eyes, purulent discharge, and chemosis. The discharge is thick and mucopurulent. Which is the most common bacterial cause of acute purulent conjunctivitis in children in India?

Explanation

## Most Common Bacterial Cause of Acute Purulent Conjunctivitis in Children **Key Point:** Streptococcus pneumoniae is the most common bacterial cause of acute purulent conjunctivitis in children globally and in India, accounting for approximately 30–40% of bacterial conjunctivitis cases. ### Clinical Features of Pneumococcal Conjunctivitis - Acute onset of mucopurulent discharge - Chemosis and lid edema - Typically unilateral but may become bilateral - Self-limited course (resolves in 1–2 weeks without treatment) - Risk of secondary keratitis if untreated ### Epidemiology in Indian Pediatric Population | Organism | Frequency | Age Group | Discharge Type | |----------|-----------|-----------|----------------| | *Streptococcus pneumoniae* | 30–40% | All ages, esp. children | Mucopurulent | | *Haemophilus influenzae* | 20–30% | Children < 5 years | Mucopurulent | | *Staphylococcus aureus* | 15–25% | All ages | Purulent | | *Neisseria gonorrhoeae* | Rare in children | Neonates (ophthalmia neonatorum) | Purulent | **High-Yield:** In the Indian pediatric population, *S. pneumoniae* remains the leading cause despite the introduction of pneumococcal conjugate vaccines (PCV7/PCV13), because vaccine coverage is not universal and serotype replacement occurs. ### Management Principles - Topical antibiotics (fluoroquinolones or aminoglycosides) - Systemic antibiotics if keratitis or systemic signs are present - Supportive care and hygiene measures **Clinical Pearl:** Pneumococcal conjunctivitis often has a benign course and may resolve spontaneously, but treatment is recommended to prevent complications and reduce transmission.
