Russian virologist Galina Kompants said that the transmission of bubonic plague between humans is possible only through personal friction. As for the spread of the disease by terrestrial squirrels, out of reach, it is possible only in rare cases.
"The infection of this very serious disease is transmitted between humans, through direct contact with the patient," added Cumbantes, who is chief researcher at the experimental laboratory for virology of the Institute for Scientific Research in Epidemiology and Microbiology. She pointed out that the cause of the disease is transmitted to humans, through blood, by a wound or scratch in the body and from there it moves to the lymph node - which is considered the first barrier to the disease. In the lymph node, bacteria begin to multiply, the node becomes inflamed, and swells - to form abscesses that become so large that they can be seen from under the skin. If the victim's body is strong, the infection stops at this level. But if you get to the blood, it will pass to the lungs, and then the infection will be transmitted by respiratory droplets. According to "Russia Today".
The expert noted: “In practice there are natural foci of this plague all over the world. In the Eurasia region, one of the foci is - in northern China, Inner Mongolia, Mongolia, and the lands bordering it. This plague carries terrestrial squirrels and between them the bacteria that cause the plague is transmitted by Direct contact with biting. Humans may become infected through contact with a sick animal or flea bite. There is no difference whether the animal is dead or alive.
