What is it?
Bubonic Plague is commonly known as The Black Death. In the 1330s, a large number of natural
disasters and plagues led to
widespread famine, starting in
1331, with a deadly plague
arriving soon after. It was an endemic that took many lives in
Europe between the years of 1346 and 1353
How did it
The causative agent for Black Death is Yersinia pestis. Bubonic Plague is spread among rodents and has
fleas as vector. Therefore it is a zoonosis. It is very rare for bubonic plague
to spread from one human to the next
The most apparent reason for the outbreak of this plague was due
to the tendency of rodents to build nests around human colonies which allowed
easy transmission of the disease.
Bubonic plague infects your lymphatic system and causes
inflammation of your lymph nodes. When left untreated, it can spread to the
blood and cause septicemic plague or spread to the lungs to cause pneumonic

diagnosis to confirm bubonic plague.
Symptoms also include swollen lymph nodes, which can be as large
as chicken eggs, in the groin, armpit or neck. They may be tender and warm.
Others include fever, chills, headache, fatigue and muscle aches.
How was a cure found?
The cause of plague had not come across until the most recent
global outbreak, which started in China (1855-1959). Researchers were able to isolated the
rod-shaped bacillus responsible—Yersinia
pestis for the first time in 1894. A few years later, in China, doctors
started realising that rats showed very similar plague symptoms to people, and
that human victims often had fleabites.
