Tularemiasis is an acute infectious zoonotic disease, which is characterized by fever, symptoms of damage to the respiratory, nervous system, lymph nodes and spleen and other various manifestations, depending on the type of pathogen, its virulence, ways and means of penetration into the body, the severity of the lesion, and the form of the disease. Tularemization is a slow genetic infection that is caused by a change in the genotype of immunologically sensitive cells. The viability of tularimium bacteria persists for 20 years in various habitats (soil, water, plants, rodents, etc.).
The disease is widespread throughout the world. Mortality ranges from 5% to 40%. The incubation period can range from two days to three weeks.
