Yellow fever

A quarantine disease that is spread by mosquitoes, with the development of severe hemorrhagic syndrome, with damage to the liver and other digestive organs, is called yellow fever - endemic (rural, forest) and epidemic (urban).

The development of the disease is provoked by an arbovirus, about 35 mm in size, spherical in shape, which remains frozen for a very long time, and is sensitive to conventional disinfectants. Such a virus is isolated from the blood and plasma of a sick person during the first three days.

The source of the endemic yellow fever virus are monkeys, rodents, and hedgehogs. Men who work in the forest area are more likely to get sick. The fever virus that has penetrated into the settlement leads to the formation of an epidemic outbreak. The source of infection in this outbreak is a human, and the vector is a mosquito.

Yellow fever is classified as an obligate, transmissible disease. The infected virus enters the regional lymph node, where it begins to multiply. After a couple of days, the skin of a fever patient turns yellow, the liver is affected, necrosis appears on the kidney cells, the kidneys increase in size. There is hemorrhage in the stomach, intestines, lungs, pericardium, pleura and other organs, perivascular infiltration.

The clinical symptoms are divided into:
• the initial stage;
• the stage of remission;
• the reaction stage.
The initial (febrile) stage is manifested by active hyperemia, with a duration of 3 to 4 days. Patients have severe headaches, dizziness, nausea, sometimes vomiting with mucus, severe thirst, insomnia, pain in the lumbar region and lower extremities.
