Can the plague be cured now? What are the ways to spread symptoms?

Recently, a case of plague has been confirmed in Bayannur, Inner Mongolia and Mongolia, and at present, in the prevention and control of plague, many people do not know much about plague, and some do not know at all about the disease, which can infect people and lead to death in serious cases. Can plague be cured now? What are the ways to spread symptoms?

I. introduction to the plague:

1. which animals will be infected with plague?

Plague is a natural infectious disease, which is mainly prevalent among rodents. Rats and marmots are the natural hosts of Yersinia pestis. Generally, wild mice, marmots, hares, wild cats, foxes, wolves and other animals may carry Yersinia pestis. Plague is a severe infectious disease caused by Yersinia pestis. It is an internationally quarantined infectious disease and a class An infectious disease among legal infectious diseases in China. It ranks first among 39 legal infectious diseases.

2. How did the plague come from?

The plague (the Black death) originated in Central Asia. When the Mongol army attacked the Black Sea port city of Kafa (now the Ukrainian city of Feodosia) in 1347, the plague was introduced, then spread from Eurasian merchants to Europe, and then first from Italy to Western Europe. It then spread to Northern Europe, the Baltic Sea (the lowest salinity sea in the world) and then to Russia and other countries. The earliest record of plague was recorded in 1348 by a Florentine named Bocazio.

Can the plague be cured now?

There is no cure for plague because it can be transmitted to people. Plague has the advantages of acute onset, short course, high mortality, strong infectivity and rapid spread. In particular, septicemic plague and pneumonic plague, if left untreated, the case fatality rate is 30% 100%. The incubation period of plague is short, usually 1-6 days, but in some cases it can reach 8-9 days.

What are the ways of transmission of plague symptoms?

1. Symptoms of plague: the main clinical types include bubonic plague, pneumonic plague and septic plague, while other types of plague such as skin plague, intestinal plague and tonsil plague are relatively rare.

(1) bubonic plague: the main clinical manifestations were high fever, chills, nausea and vomiting, headache and limb pain, facial flushing, conjunctival congestion, skin and mucous membrane bleeding and so on. The most common manifestations were enlarged inguinal lymph nodes, axillary lymph nodes and cervical lymph nodes, and developed rapidly, mostly unilateral, and the lymph nodes suppurated and ruptured quickly after a week.

(2) the main clinical manifestations of pneumonic plague are acute onset, fear of cold and high fever, headache and chest pain, shortness of breath, purple lips, cough, coughing mucus or bloody foamy sputum, and often die of heart failure, bleeding and shock.

(3) the main clinical manifestations of septic plague are high fever, chills, confusion, coma, septic shock, disseminated intravascular coagulation and extensive skin bleeding and necrosis.

2. The route of transmission of plague:

The main results are as follows: (1) the mode of transmission of flea bites is rat-flea-human, that is, fleas bite diseased mice and then bite people, or peel off the skin of marmots or other infected animals. This mode of transmission often causes bubonic plague or septic plague.

(2) the mode of human-to-human transmission, that is, healthy people who come into contact with patients with pneumonic plague are inhaled through the respiratory tract, which is mainly pneumonic plague.

Generally speaking, plague cannot be cured now, and we can only rely on us to strengthen prevention and control. Generally speaking, we should wear long clothes and trousers when we go out to reduce flea bites or minimize exposure to places infested by pneumonic plague patients, so that we will not be infected.
