Acute Conjunctivitis, Bacterial: Sensitivity and Specificity

Introduction: Acute conjunctivitis can be either viral or bacterial. One study in children had a 54% prevalence of bacterial etiology (42% H flu, 12% S pneumo) and 20% prevalence of adenoviral, with ~30% culture negative [J Pediatr. 1981 Apr;98(4):531-6. PMID: 6970802]. Another study in adults showed that 32% of patients had a bacterial etiology, with 47% S pneumo, 23% S aureus, 16% H flu [BMJ. 2004 Jul 24;329(7459):206-10. PMID: 1520119].
