Bubonic plague
Kevin Gamboa - 901

Bubonic plague is caused by the Yersinia pestis bacteria. It is spread by contact with infected flies.

Symptoms include swollen lymph nodes, which can be the size of a chicken egg, in the groin, armpits, or neck. They can present sensitivity and heat.

Symptoms include swollen glands, which can be the size of a chicken egg, in the armpits or neck. They can present sensitivity and heat. Other symptoms include fever, chills, headache, fatigue, and muscle aches.

Bubonic plague requires urgent hospital treatment with a strong dose of antibiotics. The first symptoms are similar to those of the flu and appear one to seven days after exposure to the bacteria. These symptoms include fever, headache, and vomiting. The swollen and painful lymph nodes occur in the most affected areas to the area where the bacteria entered the body. Due to inflammation of the lymph nodes, they may open and expel purulent material to the outside. Bubonic plague is an infection in the lymphatic system caused by the bite of an infected flea, Xenopsylla cheopis (the rat flea). The flea is a parasite in house and field rats, looking for another prey when the rodent it lives in dies. The bacteria are located in the digestive tract of infected fleas in such a way that when the flea bites, it regurgitates the intestinal contents, which infects the point of the bite. In this way the bacteria cross the skin and reach the lymph nodes, where they can resist phagocytosis and even reproduce within the phagocytes and kill them.
