The term "hemorrhagic fever" includes a whole group of diseases of a viral origin. The greatest role in this is given to vascular damage, the development of thrombi, as well as bleeding.
Types of hemorrhagic fevers
It should be said that for today, the following varieties can be classified as such:
- yellow fever;
- fever Ebola;
- Congo-Crimean fever;
- Crimean fever;
- fever with kidney syndrome , etc.
Common symptoms of hemorrhagic fever
All fevers are almost identical and have several stages of development:
- incubation stage (depending on the virus lasts from a day to three weeks);
- the period of the prodrome (duration from day to week);
- the period of the height of the illness (from one to two weeks);
- the stage of convalescence or recovery (in some cases, a lethal outcome).
In humans, hemorrhagic fever has the following symptoms at the initial stage:
- general intoxication;
- pressure reduction;
- heat;
- violation of the rhythm of the heart (decrease or increase in heart rate);
- upset of consciousness down to delirium;
- hemorrhages in the neck, face, sclera, mouth (punctate).
At the same time, a blood test can show the presence of an inflammatory process with a small decrease in platelets.
Distinguishing signs of diseases
Symptoms of Ebola haemorrhagic fever:
- signs of sore throat;
- tonsillitis;
- vomiting;
- stomach ache;
- diarrhea;
- cutaneous hemorrhage;
- encephalopathy in the form of excitation and aggressiveness of the patient.
Symptoms of Congo-Crimean hemorrhagic fever:
- excitation is replaced by fatigue and drowsiness;
- pain in the right hypochondrium;
- enlargement of the liver;
- hyperemia of the face, neck, mucous membrane of the mouth;
- lowering blood pressure;
- bradycardia;
- pallor;
- acrocyanosis;
- tachycardia and hypotension;
- depression of mood right up to depression;
- lymphadenopathy ;
- enlargement of the liver;
- convulsions, delirium and coma;
- meningeal symptoms.
Also, the symptoms of the Crimean hemorrhagic fever can be manifested as:
- headache;
- aches in the body;
- pain in the calf muscles;
- hemorrhagic rash;
- conjunctivitis.
During the height of the disease, the temperature can rise significantly, and the kidneys, liver, lungs, and heart can be damaged. There are thromboses, as well as minor hemorrhages at the injection site. As the toxicosis rises, the patient's consciousness may also be violated. With a favorable course of the disease and timely treatment, all symptoms gradually go away. In some, especially severe cases, a lethal outcome is possible.
