A39.4: Meningococcaemia, unspecified

You have been infected with meningococci.

You have been infected by certain bacteria called meningococci. These bacteria are typically transmitted person-to-person, for example by sneezing or shaking hands. The bacteria have given you blood poisoning.

The body’s immune system reacts to bacteria and toxic substances. With blood poisoning, they can spread throughout the body via the blood. The immune system is usually closely controlled. With blood poisoning, these controls do not work properly. As a result, the functioning of organs in the body is disrupted.

Meningococci can also remain in the blood for a considerable time and repeatedly cause fever and headaches. The joints may also ache. A skin rash is also possible.

  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
