Did you show any signs after the plague 15

You, gotcha? Shootable! Be sure to quarantine!

It's still possible to get the plagueHuman contact with infected animals and people with pneumonic plague is susceptible to plague because plague is mainly transmitted by droplets. The incubation period of plague is short, and infected people have severe symptoms of systemic poisoning and symptoms specific to respiratory tract infection. Host animals include rodents and wild carnivores, such as gray marmots, red marmots, Himalayan marmots, and long-tailed yellow squirrels.

1. Mode of transmission

1. The mode of transmission of flea bites

Rat-flea-human, in which fleas bite a sick rat and then bite a human, or peel an infected marmot or feed on other infected animals, often cause bubonic plague or septicaemic plague.

2. Human-to-human transmission mode

That is, a healthy person who comes into contact with a patient with pneumonic plague and inhales the infection through the respiratory tract, and this mode of infection is mainly pneumonic plague.

2. Susceptible populations

Humans are generally susceptible to plague. People engaged in field work in endemic areas, hunters and herders who hunt and flake marmots are more likely to come into contact with infected animals, and the likelihood of infection is higher than that of the general population.

Yes, hehe, everyone knows about the things of the past few days, and it's on the news.

The symptoms of plague are generally high fever, swollen and painful lymph nodes, bleeding tendency, and special inflammation of the lungs. Moreover, plague was originally an infectious disease that was endemic among rats, so why did humans get plague? The answer is that plague in the population is spread by fleas.

Therefore, the main culprit of plague in humans is fleas. At least 30 species of fleas have been found to transmit plague, of which there are more than 10 species, and these more than 10 species of fleas are basically parasitic on rodents.

When the flea inhales the blood of the rat containing the germ, the germs multiply in the forestomach of the flea and can form bacterial embolus, and when the flea bites other rats or people, the blood full of bacteria will flow back into the wound of the flea bite, so that the bite target will be infected. Flea feces also contain plague bacteria, flea feces pull on the human **, when itching, the germs can invade the human body through scratching.

This rat-flea transmission of people is the main mode of transmission of plague. In addition, it can also be transmitted by peeling the skin and flesh of sick rats, or by directly contacting pus, blood or phlegm from sick people. Some wild animals, such as marmots and foxes, can also be infected with plague, so they can also be infected with plague when hunting or being bitten by a sick animal.

Primary pneumonic plague and pneumonic plague transformed from bubonic plague can spray droplets containing plague bacteria when breathing, talking and coughing, causing people around them to inhale and get sick, causing plague epidemics. In addition, when skinning sick rats or wild animals, plague bacteria can also be inhaled, causing pneumonic plague in humans.

Experts from the infectious disease hospital reminded friends: plague has been listed as a class A infectious disease in our country, no matter where the plague patient is found, it should be reported to the local health and epidemic prevention agency immediately, the patient should be strictly isolated**, and the surrounding residents should not go out casually for a period of time, and the doctor will observe whether the plague is infected.

It is also possible to get infected by someone else, or if you eat food that can get plague, or if you come into contact with someone who is very weak.

The plague is not so easy to get.

Plague is a natural iatrogenic disease caused by Yersinia pestis.

Rats infected with plague are mainly infected by flea bites on rats. When a person is infected, he gets bubonic plague, which is a high fever and swollen lymph nodes.

Primary pneumonic plague is caused by the introduction of plague bacteria into the lungs through aerosols when infecting infected animals.

Humans can be infected with plague only if you live or have been to a plague foci and that there is an animal plague epidemic.

If you don't advertise plague prevention in your area, you can rest assured that it is not a plague foci.

The incubation period for bubonic plague is usually 2-8 days, and for primary pneumonic plague and septic-type plague, it can be as long as a few hours to 3 days, and for those who have been vaccinated, it can be as long as 9-12 days. The onset is abrupt, with chills, fever and systemic toxemia symptoms, vomiting, diarrhea and bleeding from various parts of the body, shortness of breath, cyanosis, blood pressure drop and systemic failure. The clinical classification is bubonic plague, pneumonic plague and septicemic plague, each with its own characteristic manifestations.

1.Bubonic plague is the most common, and in addition to fever and systemic toxemia symptoms, the main manifestation is acute lymphadenitis. At the beginning of the disease, there was lymphadenopathy and rapid development, and the lymph nodes and their surrounding tissues were significantly red, swollen, hot, and painful, reaching a peak 2-4 days after the disease.

Inguinal lymph nodes are most commonly involved, followed by axillary and cervical regions, and are mostly unilateral. If not timely, the lymph nodes will quickly suppurate and break down, and they will die within 3-5 days due to severe toxemia, shock, secondary sepsis or pneumonia.

2.Pneumonic plague can be primary or secondary to bubonic plague. Acute onset, high fever and systemic toxemia symptoms, cough, shortness of breath, chest pain, sweet and sputum production, a small amount of mucus sputum at first, followed by foamy or bright red blood sputum, the lungs only hear scattered crackles or pleural friction rubs, and fewer pulmonary signs are not commensurate with severe systemic symptoms.

Death often occurs within 2 to 3 days due to heart failure, hemorrhage, shock, etc. Before dying, the patient's whole body was cyanotic and black-purple, so there was"The Black Death"called.

3.The septic-type plague is often secondary to pneumonic plague or bubonic plague and is the most dangerous type. Acute onset, chills, high fever or body temperature does not rise, delirium or coma, followed by septic shock, DIC and extensive ** hemorrhage and necrosis, etc., the disease develops rapidly, if not timely** often dies in 1-3 days.

4.Other types of plague, such as plague, meningeal plague, enteric plague, ocular plague, tonsil plague, etc., are rare. [

One more point:

The typical symptom of plague is a critical provincial poisoning symptom, with a sharp onset, chills and shivers, a sudden rise in body temperature to 39-40, and a residual fever. The headache is severe, sometimes with central nervous vomiting, dizziness, shortness of breath, and soon a state of extreme weakness. Tachycardia, irregular heartbeat, weak heart sounds, pulse more than 120 beats per minute.

1.Mild has irregular low-grade fever, mild systemic symptoms, swelling and pain of local lymph nodes, occasional suppuration, no bleeding, and is more common in the early and late stages of the epidemic or in vaccinated people.

2.Glandular forms are the most common and often occur in the early stages of an epidemic. Sudden chills, high fever, headache, fatigue, body aches, occasional nausea, vomiting, irritability, ecchymosis, bleeding.

3.The pulmonary type may be primary or secondary to the glandular type. Pneumonic plague developed rapidly, with rapid onset of high fever, obvious symptoms of systemic poisoning, chest pain, cough, and sputum production appeared a few hours after the onset of the disease, and the sputum quickly turned from a small amount to a large amount of bright red bloody sputum.

4.Sepsis can be primary or secondary. The primary disease develops rapidly, with severe symptoms of systemic toxemia, central nervous system symptoms, and hemorrhage.

The plague is characterized by a rapid onset, chills, fever, a sudden rise in body temperature to 39 41, a lingering fever, severe headache, and sometimes central vomiting, shortness of breath, tachycardia, and a drop in blood pressure.

In severe cases, blood pressure, unconsciousness, and delirium can occur in the early stage.
