Meningococcal Infection: Pathogenesis, Impact, and Interventions - E-book - ePub

Meningococcal infection, caused by the bacterium Neisseria meningitidis, stands as a formidable global health concern due to its swift onset, severity, and potential for devastating outbreaks. This infection manifests in various forms, ranging from asymptomatic carriage to life-threatening invasive disease, primarily affecting the central nervous system. The pathogenesis of meningococcal infection hinges on the bacterium's ability to evade the body's defenses and invade the bloodstream, subsequently crossing the blood-brain barrier, leading to meningitis or causing septicemia.
Neisseria meningitidis possesses a polysaccharide capsule that aids in immune evasion, while its outer membrane components trigger robust inflammatory responses, contributing to tissue damage and systemic complications. The impact of this infection reverberates through diverse channels, affecting individuals, communities, and healthcare systems worldwide. Its sudden onset and rapid progression often result in significant morbidity and mortality, particularly in young children and adolescents.
Survivors might grapple with debilitating neurological sequelae, including cognitive impairment, motor disabilities, and mental health challenges, imposing long-term burdens on affected individuals and their families.
