Glandular plague is a severe type of bacterial infection that is commonly spread by fleas. Small rodents, which are most frequently found in rural and semi-rural parts of Asia, Africa, and the United States, are habitat to the plague-causing organism Yersinia pestis. When people handle infected animals or are attacked by fleas that have eaten infected rats, the virus is spread to humans.
Currently, less than 5,000 individuals worldwide contract the plague each year, which was once known as the “Black Death” during the Middle Ages. If antibiotics are not administered right away, it could be fatal. The most typical type of plague causes sore and swollen lymph nodes, known as buboes, in the armpit, neck, and groin. The most deadly and uncommon variety of plague affects the lungs and is contagious.
