The Plague

It plagues small pox. Tuberculosis AIDS These diseases are considered epidemic at all stages of world history. But none of them has such influence on black population and culture. Black death is a disease that invaded Britain in the mid-14th century. The report on total deaths varies between 25% and 50% of the European population. However, it is well known that millions of people are excluded from the UK population and black death is a promoter of social change within Europe.

The three types of plague are the result of the infection route. Bubonic plague, septic plague, and pulmonary plague. Pest is spread mainly by fleas infected with small animals. It can also be caused by exposure to bodily fluids from plague-infected animals. In the acinar plague, the bacteria bite into the skin through the flea, enter the lymph nodes through the lymph duct, and inflate them. Diagnosis by finding blood, sputum or liquid bacteria from lymph nodes

Pest is the most common form of plague and is caused by infected fleas. Y. musis enters from a bite and reaches the nearest lymph node through the lymphatic system where it replicates. Lymph nodes then develop inflammation, become nervous, accompanied by pain, and are called "inguinal lymphadenitis". At the late stage of infection, inflamed lymph nodes may become open pus filled with pus. The plague spread among people is rare. Although plague may progress and spread to the lungs, this is a more serious type of plague called pneumonia plague.

The general form of plague is the most common form of plague. It usually occurs after infected flea bites. The main feature of the glandular plague is swollen, painful lymph nodes, usually in the groin, armpits, or neck. Other symptoms include fever, chills, headaches and extreme fatigue. People usually suffer from plague 1 to 6 days after infection. Failure to treat early may spread bacteria to other parts of the body, causing sepsis or pulmonary plague.

Pneumonic plague or lung-based plague is the most virulent and least common form of plague. Typically, the form of pneumonia is caused by the spread of threatened plague to the lungs. However, people with secondary pulmonary plague may form misty infectious droplets and spread the plague to other people via droplets. The mortality rate of untreated pulmonary plague is close to 100%. Laboratory testing is required to confirm the plague. The best practice is to identify the plague in the vaginal sample from inguinal lymph nodes, blood or sputum. Certain pestobacterial antigens can be detected in various ways. One of them has been verified in the field and is a rapid test paper test widely used in Africa and South America with the support of the World Health Organization.
