Meningococcal disease starts with the organism🧫🔵🔬⚠️
Neisseria meningitidis is a Gram-negative, encapsulated diplococcus that can be carried asymptomatically in the nasopharynx by up to 24% of young adults, peaking between ages 18-20. A small proportion of N meningitidis strains can rapidly transition from commensal to invasive pathogen, leading to meningitis and septicemia with high morbidity and mortality.
🚨 A notifiable disease in the UK, understanding the organism is central to prevention strategies, including targeted vaccination and outbreak control.
