K fever


Fever Ku is an infectious disease of animals and humans caused by a microorganism belonging to the rickettsia group. It is characterized by many ways of distribution and a very diverse form of manifestation. In Europe, this disease was first recorded in 1941 in the Balkans, which is why it is sometimes called the Balkan flu. There are other names: a seven-day fever and a fever of slaughterhouses.

In 1937, doctors described for the first time a flu-like disease, caused not by viruses, but by bacteria. This disease, characterized by high fever, was first recorded in Australia, in the state of Queensland.

Since infection comes from cows, sheep and goats, the disease is particularly affected by agricultural workers. At the end of the fourth decade of the XX century. In Germany and Switzerland there was an epidemic of this disease. Symptoms of this disease are similar to those of influenza and pneumonia. Fever lasts 7 days (less often - up to 14 days). After the transferred disease, residual changes in the lungs and in other organs are possible.

  • Cough.
  • Sputum with blood.
  • Headache.
  • Diarrhea.
  • Pain in the testicles.
  • Heartache.
  • Impaired breathing.

Clear symptoms of the disease occur suddenly after about three weeks after infection. Bacteria are introduced into various cells of tissues, there multiply, destroying cells, and spreading further. Then the inflammation of the lungs and bronchi begins, later the pleura, the heart muscle, the pancreas, the men's ovaries and their appendages are affected. Possible damage to the brain. If bacteria enter the body by airborne droplets, the disease is primarily manifested by pneumonia, if - with milk, then the onset of the disease will be inflammation of the liver and jaundice. The disease is manifested by severe diarrhea, coughing, headache, fever up to 39-40 ° C. As a rule, after seven days the illness suddenly passes. But after it, fatigue and a headache may last for a long time.
