Meningitis meningococcal

Meningococcal meningitis is cased by the bacterium Neisseria meningitidis. It can be transmitted through direct contact including airborne droplets from nose and throat of infected persons. 


Incubation period
3 to 4 days, but can vary from 2 to 10 days.

Signs and Symptoms
  • Fever
  • Intense headache
  • Nausea
  • Vomiting
  • Neck stiffness
  • Petechial or purpuric rash on the trunk and limbs
  • Can lead to sepsis, pneumonia and death.

Clinical features & blood and CSF culture

Prompt treatment with parenteral penicillin (prescribed by medical doctor) in adequate doses should begin when a presumptive clinical diagnosis is made prior to laboratory confirmation.

Control and Prevention
Rifampicin or Ciprofloxacin (prescribed by medical doctor) should be given as prophylaxis to:

  • Eliminate carriage of meningococci in household members and other close contacts, thereby in turn reduce transmission to susceptible individuals who are not carriers.
  • Prevent susceptible contacts from acquiring infection by directly inhibiting colonisation but it could only be effective for 2 days prophylaxis.
  • Treat the newly acquired nasopharyngeal or blood borne infection in contacts who are non-immune and may be incubating the disease.
