Bacterium Yersinia pestis
Bubonic plague / Black Death
bacterium Yersinia pestis > bubonic plague
Bubonic plague is one of three types of plague caused by bacterium Yersinia pestis.
One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting.
Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin.
Occasionally, the swollen lymph nodes may break open.
The three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. Bubonic plague is mainly spread by infected fleas from small animals.
It may also result from exposure to the body fluids from a dead plague-infected animal. In the bubonic form of plague, the bacteria enter through the skin through a flea bite and travel via the lymphatic vessels to a lymph node, causing it to swell.
Diagnosis is made by finding the bacteria in the blood, sputum, or fluid from lymph nodes.
Prevention is through public health measures such as not handling dead animals in areas where plague is common.
Vaccines have not been found to be very useful for plague prevention.
Several antibiotics are effective for treatment, including streptomycin, gentamicin, and doxycycline.
Without treatment, plague results in the death of 30% to 90% of those infected.
Death, if it occurs, is typically within ten days. With treatment the risk of death is around 10%. Globally between 2010 and 2015 there were 3248 documented cases, which resulted in 584 deaths.
The countries with the greatest number of cases are the Democratic Republic of the Congo, Madagascar, and Peru. https://en.wikipedia.org/wiki/Bubonic_plague - 12 April 2020

Black Death, a kind of bubonic plague, is one of several strains of plague.
It got its frightening name because those infected developed gangrenous, blackened lesions all over their body.
The disease is characterized by fever and swelling of the lymph nodes and caused by the bacterium Yersinia pestis, which spreads via rodents carrying infected fleas.
