Crimean-Congo Hemorrhagic Fever

Congo-Crimean hemorrhagic fever is an acute viral disease. Congo-Crimean hemorrhagic fever is characterized by two-wave fever, intoxication of the body and severe thrombohemorrhagic syndrome.

Congo-Crimean fever, or rather. its causative agent was discovered in 1945 by M. Chumakov. This virus contains RNA and is localized in the cytoplasm. Congo-Crimean hemorrhagic fever was found in the Crimea, Astrakhan, Rostov regions, Krasnodar and Stavropol territories, as well as in Central Asia, China, Bulgaria, Yugoslavia, Congo, Kenya, Uganda, Nigeria.

The reservoirs of fever are the wood mouse, the small gopher, the brown hare, the long-eared hedgehog and other small mammals, and the disease is transmitted by ticks. The disease most often manifests itself in the summer. The incubation period lasts up to two weeks; Crimean-Congo hemorrhagic fever has no warning signs and begins suddenly.

Symptoms of fever:

Congo-Crimean hemorrhagic fever begins with chills and increased body temperature (even with a mild form of the disease, about 39-40 ° C). Initially, only signs of general intoxication, characteristic of many infectious diseases, are noticeable.

The initial period lasts from 2-3 days to a week. At this time, patients complain of weakness, weakness, headache, aches throughout the body, pain in muscles and joints. Dizziness, fainting, pain in the calf muscles, and inflammation of the upper respiratory tract may also occur.

With further development, repeated vomiting occurs that is not associated with food intake, lower back pain, and abdominal pain. However, the most characteristic symptom is fever. It lasts 7-8 days. Crimean-Congo hemorrhagic fever is also characterized by a temperature curve. First, the temperature drops, then after 1-2 days it rises again - this is how a “two-humped” temperature curve is obtained.

It is also impossible to have Congo-Crimean hemorrhagic fever without a hemorrhagic rash. As a rule, it appears on the 2-4th day of illness on the skin and mucous membranes, at injection sites, and bleeding is also possible. The patient turns pale, swelling of the face and cyanosis of the lips appear. Along with the rash, bleeding gums and conjunctivitis are possible.

Abdominal pain intensifies, vomiting and diarrhea continue, the liver becomes enlarged, and bleeding of internal organs is possible.

The disease lasts up to 10-12 days. Recovery is often accompanied by a long period of asthenia.
