Eight regions of South Federal District report about 220 morbid events of Congo-Crimean hemorrhagic fever, carries by mites.
      
      Virus of said hemorrhagic fever was discovered by Russian scientist Mikhail Chumakov in 1944, and later the same virus was found in the Congo river basin. The virus lives in small animals – squirrels and hedgehogs – and is carried from one animal to another by mites.
      
      First symptoms of this fever remind of ordinary respiratory infection – headaches, temperature rise and fever. Then small hemorrhages appear inside and sometimes outside the patient, followed by the second wave of fever.
      
      Population of the Russian South has natural immunity against Congo-Crimean hemorrhagic fever, thus visitors should take care and visit a doctor after being bitten by a mite.
