Final answer:
The bubonic plague, caused by Yersinia pestis, featured symptoms such as pus-filled abscesses in lymph nodes, elevated heart rate with low blood pressure, and necrotic blackened skin; increased appetite and absence of fever are not symptoms. The Black Death had a high mortality rate, but modern treatment has significantly reduced this. The correct answer is option B&C .
Step-by-step explanation:
The bubonic plague caused by Yersinia pestis has been one of the most devastating pandemics in history. The Black Death of the 14th century is the most infamous outbreak, causing a significant decline in Europe's population. Symptoms of this affliction are well-documented and include pus-filled abscesses in the lymph nodes, also known as buboes, which when burst, emit a foul odor; an elevated heart rate with low blood pressure due to septicemic shock; the absence of fever is not a symptom and neither is increased appetite, contrary to normal human response to infection.
Abscesses in the lymph glands of the groin or armpits are one of the tell-tale signs of bubonic plague, along with severe fever and the potential for skin to turn black and necrotic. The Black Death was notorious for its high mortality rate, which was much higher than more recent pandemics.
In modern times, bubonic plague is rare, with approximately 1,000 to 3,000 cases yearly. However, unlike during medieval times, due to advanced healthcare and the availability of antibiotics, mortality rates from the plague are now significantly lower.
