What are plague symptoms and signs? What are the different types of plague?
The signs and symptoms of plague may take three forms:
1. Bubonic plague
In this form of the infection, bacteria infiltrate the lymph nodes, causing enlarged, painful, tender lymph nodes called buboes. Accompanying symptoms are fever, chills, headaches, and weakness. If not treated, the infection can spread to other areas of the body
2. Septicemic plague
This form of plague is a result of plague bacteria entering the bloodstream. It can occur on its own or may develop from bubonic plague. Symptoms include fever, chills, weakness, abdominal pain, and shock. There can be bleeding and tissue death, especially of the fingers and toes. These dying tissues may appear black, hence the name Black Death.
3. Pneumonic plague
In this form of the illness, symptoms of other types of plague can be present, but the characteristic clinical picture of pneumonia is present. The plague bacteria spread to the lungs or infect the lungs directly when infected droplets in the air are inhaled. This is the only form of plague that can be transmitted from person to person. Shortness of breath, chest pain, and cough with watery or bloody mucus production are symptoms of pneumonic plague.
