Meningococcal meningitis is an infection caused by theNeisseria meningitidis, also called meningococcus. Grouped into 12 letter-designated serogroups, serogroup A, B, C, W, and Y strains are responsible for 99% of diagnosed infections. In France, in 2019, plus d’un cas sur deux (53%) is caused by meningococcal B, more Santé published France noted that meningococcal W is more frequent between 2018 and 2019, passing from 14% to 21% cases. A worrying trend as this hypervirulent serogroup has the highest case fatality rate and accounted for 45% of deaths in 2019.
Invasive meningococcal disease, an unpredictable and serious disease
The infection is unpredictable. theit does via prolonged contact with respiratory infections. Neisseria meningitidis can be found in the microbial flora of the throat, without the person developing . Almost 30% of young people between the ages of 15 and 25 are healthy carriers. The passage of the bacteria through the respiratory mucosa allows it to reach the blood and reach the . This spread of the bacteria will trigger different symptoms.
Difficult to diagnose, a meningococcal infection initially causes nonspecific symptoms that do not distinguish it from other diseases:flu, fatigue, pain, etc. When the symptoms clear up, the infection is already installed. In adults, this infection causes photophobia, irritability, headaches, and vomiting; and in children, due to behavioral and communication disorders. .
The acute phase evolves rapidly, the condition of patients can deteriorate in a few hours if nothing is done. All serogroups combined, invasive meningococcal disease is fatal in approximately 10% of cases. Up to 20% of survivors may suffersevere and disabling. Hearing loss, learning disabilities are examples of sequelae related to the initial infection.
Meningococcus and after? the story of flavio
Flavio has been living with the consequences of his invasive meningococcal infection since 2019. At the age of 17, he fell ill while studying at Clermont-Ferrand to become a professional footballer.
