  • Supportive care, such as oxygen therapy and fluids
  • Hospitalization

In severe cases, the patient requires mechanical ventilation or other life-support measures.

To prevent invasive meningococcal disease, it is important to get vaccinated against the bacterium.

  • Stay home from work or school if you are sick.
