Why is tuberculosis spreading?

Tuberculosis: symptoms, forms and mechanisms of disease

An early form of post-primary tuberculosis is that Miliary tuberculosisthat arises directly from primary tuberculosis. The pathogens spread en masse to the lungs and other organs via the blood and lymphatic systems. That is why one speaks of a primary generalization. If the meninges are also affected, this leads to meningitis (meningitis). This TB meningitis - and miliary tuberculosis in general - is a serious clinical picture that must be treated immediately. Symptoms of miliary tuberculosis are:

  • fever
  • a headache
  • neurological failures
  • Cough and shortness of breath
  • Night sweats

Miliary tuberculosis can occur in people whose immune system is weakened at the time of infection. But they can also be observed in infants and young children and very old people. Fortunately, this form of tuberculosis has become very rare in Germany.

In reactivated tuberculosis, there is a symptom-free interval between the initial infection and the flare-up of the disease, which in certain circumstances can last for decades. The lungs are particularly affected. But the pathogen can also affect other organs. Classic places for such organ tuberculosis are:

  • the pleura
  • the kidneys and the lower urinary tract
  • the bones
  • the lymph nodes

The symptoms of tuberculosis depend on which organ or organs are affected.
