Where can I get Yersinia pestis?

summary

Yersinia pestis is a very large number of patients with this disease, and its source of infection is also very many. When plague is found in life, we should cut off the source of infection in time, find out the cause and pathogenesis of the disease, and have a healthy future in life. Now let's understand it together.

Where can I get Yersinia pestis?

First, through fleas as as the media, the transmission route of "rodent → flea → human" is formed. The main vector is rat fleas. After fleas inhale the blood containing bacteria, Yersinia pestis will multiply in their forestomach, forming a bacterial embolus to block the digestive tract. When they bite other mice or people, the blood inhaled will be blocked and the bacteria will invade and form infection. Flea dung also contains bacteria, which can invade the human body through skin wounds due to itching. Other blood sucking vectors, such as ticks, bedbugs and lice, can also carry Yersinia pestis under natural conditions.

Second, direct contact between human and infected animals (including livestock), vector insects, plague patients and their corpses, secretions and excreta with bacteria can cause infection. Hunting or stripping marmot is one of the common direct contact infection routes. It can be infected through skin wound by stripping the skin or meat of rodents or directly contacting the pus or sputum of patients. When the natural foci have been controlled to some extent, especially the first case, it is more important to catch Marmota and other economic animals through skin contact infection.

Third, the patients with secondary or primary pulmonary plague can spread the plague from person to person by breathing, talking, coughing, sneezing, etc. through the respiratory tract with the help of droplets, and quickly cause the epidemic of pulmonary plague; In the process of shelling infected animals, direct infection can be caused through respiratory tract due to splashing of droplets. Generally speaking, bubonic plague does not pose a threat to the surrounding area.

matters needing attention

We have a certain understanding of the pathogenesis of Yersinia pestis. In our life, patients should strengthen their understanding of the disease, grasp its symptoms in time, and find treatment methods in time. Family members must pay attention to infection when nursing patients, and disinfect the articles of patients in time, so as to restore their health in time.
