EBOLA AND THE BLACK DEATH MAY
BE TERRIFYINGLY SIMILAR, SCIENCE SAYS
History does not paint the
Middle Ages as a fun time. Between 1347 and 1352, a vicious plague known as the
Black Death ravaged Europe, killing an estimated 20 million to 25 million
people — almost a third of the population at the time. History classes have
long taught that the Black Death was synonymous with the bubonic plague, a
bacterial disease spread by fleas on rodents, but in the wake of the current
Ebola outbreak in West Africa, researchers are discovering that the Black
Death could have been an Ebolalike virus. I
didn’t think the Ebola situation could get any scarier, but it just did.
Researchers Christopher Duncan and Susan Scott make
the argument that the Black Death was most likely caused by a hemorrhagic virus
like Ebola, rather than the bacteria related to the bubonic plague. The duo
looked at everything from symptoms to the way the two diseases spread. In order
to draw detailed comparisons between the medieval disease and modern Ebola,
let’s revisit history class.
So how does it compare to the
Ebola virus that is currently devastating West Africa?
Brace yourself: The Black Death earned its ominous name from the
black liquid that seeped out of swollen lymph nodes on the afflicted. The
swollen areas, which are also known as buboes, were a defining characteristic
of the disease and they usually occurred in the armpit and groin areas.
If infection reaches the
blood stream, it severely damages the organs and causes blood vessels to
hemorrhage, which then results in bleeding from the nose and ears and vomiting
blood. These extreme symptoms are also accompanied by flulike symptoms, including fever,
headaches, chills, and weakness.
Despite the similarities, it seems that modern
Ebola may be even scarier and more deadly than a disease called Black Death.
According to Dr. David Dennis, coordinator of the plague program for the
Centers for Disease Control and Prevention, victims of the Black Death, if
untreated, had a mortality rate of 50
to 60 percent. Ebola, on the
other hand, has a mortality rate of up to 90 percent.
Similarly, Ebola, which was
formerly known as Ebola hemorrhagic fever, also starts out with flulike
symptoms, including fever, headaches, and muscle aches. And like the Black
Death, Ebola victims often go through a bleeding phase that can result in
vomiting or coughing up blood and bleeding from the eyes, nose, and mouth.
