Sand fly fever

Introduction to Baijiu Sandflyfever is an acute viral disease caused by the white sputum virus that is transmitted by the ferrets. Clinically, it is characterized by fever, headache, myalgia, conjunctival hyperemia and leukopenia, and the prognosis is good. basic knowledge The proportion of illness: 0.04%-0.05% Susceptible people: no specific population Mode of transmission: insect vector transmission complication:

Chalk fever

(1) Causes of the disease

The white sputum fever virus is an arbovirus virus, and there are at least 20 serotypes. The virus can be isolated from suckling mice and hamsters, and can also be cultured with Vero cells to produce cytopathic effects.

(two) pathogenesis

The virus enters the human body through a white bite, and reaches the reticuloendothelial system through lymphatic vessels and capillaries to reproduce. After reaching a certain amount, it enters the blood circulation, causing viremia, causing systemic diseases, and invading the central nervous system.
