A plague or pestilence is a disease caused by the Yersinia pestis bacterial infection. A person may get this disease if it is bitten by a flea (insect) exposed to the Y. Pestis bacteria, after which the insects bite infected animals. The flea that transmits the bubonic plague disease by sucking the rodent blood.
Bubonic plague can evolve rapidly and result in death if it is not immediately treated. Bubonic plague is a zoonotic disease (derived from animals).
Based on the organ infected with the Plague infection, the disease can be divided into three types, namely Plague in the lymphatic system (bubonic plague), a Plague of the bloodstream (septicemic plague), as well as the Plague of the lungs (pneumonic plague).
Transmission of Yersinia Pestis to Humans
Although the Yersinia pestis is found in animals, the disease of Bubonic Plague can be transmitted to humans. One way of its transmission is through bites of rat flea or direct contact with the tissues or body fluids affected by Bubonic Plague.
Mice, dogs, squirrels, guinea pigs, cats, deer, rabbits, camels, and sheep are animals that act as intermediaries. Meanwhile, the most frequent outbreaks are fleas that are usually present in rats.
The bacteria cause the Bubonic Plague to grow and develop in the esophagus. When the flea bites the skin of the animal or human and suck the blood from the host’s body, then the bacteria come out of the esophagus and goes into the skin. Furthermore, bacteria will attack the lymph nodes until this part is subjected to inflammation.
From this, the disease of Bubonic Plague can spread to other organs. In fact, it can get to the brain membranes, although this is rare.
