Which of the following is a classic sign of plague infection?

• A. Bubonic swellings
• B. Skin discoloration
• C. Nausea
• D. Coughing blood

Answer: (A)

Bubonic swellings, also known as buboes, are indeed a classic sign of plague infection, particularly associated with the bubonic form of the disease. The term "bubonic" itself is derived from the word "bubo," which refers to the swollen, painful lymph nodes that occur in the groin, armpits, or neck areas. These swellings result from the lymphatic system's reaction to the infection caused by the bacterium Yersinia pestis, which is transmitted through flea bites or contact with infected animals or humans. The presence of these noticeably enlarged and tender lymph nodes is a key indicator that helps in diagnosing bubonic plague, differentiating it from other forms of plague or other infections. While skin discoloration, nausea, and coughing blood can occur in various infections and diseases, including some that might be caused by Yersinia pestis, they are not defining characteristics of plague. Coughing blood is more indicative of serious respiratory infections, and skin discoloration is a generalized symptom that could result from various conditions but does not specifically point to plague. Nausea can arise from many illnesses and is not specific to plague either. Thus, bubonic swellings remain the hallmark sign of this particular infection
