Often, after infection with a bacterium, a bubonic type of disease occurs.
In an infected persona slight reddening occurs in the affected area, which quickly develops into a pustule, after opening an ulcer occurs. A week after communicating with the patient, there is a sudden fever, headache, weakness, chills, swollen lymph nodes, cough with sputum. This is the result of a flea bite. If the infected person does not take therapeutic measures on time, then the infection can spread to other parts of the body.
The skin over the seals becomes reddish and shiny. After 4 days, the inflammation becomes softer, when tapped, they move. After opening, fistulas are formed. From the first day, increased nervousness, severe muscle pain may begin. The following signs are also characteristic of the plague: the patient's face darkens, circles appear under the eyes, the tongue becomes coated, and the heart rhythm is disturbed.
In the Middle Ages, the plague was practically not treated, the actions were reduced mainly to cutting or cauterizing plague buboes. No one knew the true cause of the disease, so there was no idea how to treat it. Doctors tried the most bizarre remedies. The composition of one such drug included a mixture of 10-year-old molasses, finely chopped snakes, wine, and 60 other components. According to another method, the patient in turn had to sleep on the left side, then on the right. Since the 13th century, they have been trying to limit the plague epidemic with the help of quarantines.
Black plague can be complicated by meningitis.
For the first time, a vaccine effective against bubonic plague was created at the beginning of the 20th century by Vladimir Khavkin from plague rods killed by temperature. More effective are live vaccines, that is, vaccines obtained from live plague bacilli using bacteriophages. For the first time, a live vaccine against plague was created and tested on herself in 1934 by Pokrovskaya Magdalina Petrovna.
The treatment of plague patients is currently carried out with the help of antibiotics, sulfonamides and therapeutic anti-plague serum. Prevention of possible foci of the disease consists in carrying out special quarantine measures in port cities, deratting all ships that go on international flights, creating special anti-plague institutions in the steppe areas where rodents are found, identifying plague epizootics among rodents and fighting them.
