Corge

Kor fever is an acute infectious disease caused by R. burnetii (R. burnetii, also known as R. burnetii, Kor ricketts). Founded in Australia for the first time in 1935, it is called Kou fever because it is considered to be an unexplained disease (query is a question). Livestock such as cattle, sheep, dogs, horses, mules and pigs are the main sources of infection. The clinical features are fever, headache, and general muscle pain; however, there is no rash, sometimes with interstitial pneumonia, and a few patients have chronic hepatitis or fatal endocarditis.
