People get infected by the bite of infected animals (dog, fox, cat, bat and rarely other animals). There is no cure, only the relief of the suffering is possible.

The disease is spread in several African, Asian and Latin American countries. In some cases the virus was also carried into Europe. After the bacteria have invaded the body, the incubation time is quite short, 1-2 days.

Chronic disease can get formed. 15-20% of patients suffering from chronic hepatitis dies due to the complications, and liver cancer may develop.
