Meningococcus is a serious infection which include meningitis (inflammation of the brain and spinal cord's protective membranes) and septicaemia (blood poisoning) can be caused on due to the Meningococcus bacteria (Neisseria meningitidis). Respiratory droplets from sneezing, coughing, or close contact are how it spreads. Meningococcal infections become highly contagious and can spread quickly, resulting in serious side effects such organ failure, brain damage, or even death if left untreated. High fever, headache, stiff neck, nausea, light sensitivity, and confusion are common symptoms. The best prevention against meningococcal disease is vaccination, especially for young people, tourists, and those with weaker immune systems. For the illness to be controlled, detection early and rapid antibiotic treatment are essential.
