Medicine and the Black Death in the Medieval Period
The Greek physician Galen (129-201 CE) popularised a theory about the human body, which stated that it was made up of four fluids called “humors”: black bile, yellow bile, blood, and phlegm. If there was an imbalance of any of these humors, then illness would follow.
1. Vinegar and the Black Death
The Vinegar Merchant, by Abraham Bosse, mid-to-late 17th century, via the Metropolitan Museum
2. Curing the Black Death with Onions
The humble onion was one of the home remedies that desperate doctors and patients alike tried to use to cure the plague, by rubbing chopped raw onion on the buboes (the large pus-filled boils that turned black, hence the name, the Black Death). Not only would the onion draw out toxins, it was thought that onion fumes could combat miasma.
3. Blood-Letting
Going back to Galen’s theory of the four humors, blood-letting was a common medical procedure in the Medieval Period. The idea was to allow some of the excess humors to drain out of the body. It was used as a cure-all for a variety of conditions, including epilepsy.
4. Live Chickens and the Vicary Method
This is one of the more bizarre quack cures for the Black Death. This treatment was named the “Vicary Method” after Thomas Vicary, the doctor who promulgated it. It involved plucking feathers from a chicken’s rump, and then tying the chicken to the patient, so that the chicken’s rump was touching the patient’s buboes.
5. Snakes
The Chinese had been using snakes in their traditional medicine since at least 100 CE, and snake meat was eaten to aid circulation and remove toxins from the body of a patient. During the Medieval Period, physicians would treat the plague by cutting up a snake and placing its parts on the pustules of the sufferer.
6. Leeches
Leeches were used as a treatment for the Black Death in much the same way that the fleam was — they were used to draw ‘bad’ blood out of the patient. This form of blood-letting was used for localized blood-letting (the fleam being used for generalized blood-letting).
Description
- Plague has been responsible for three great world pandemics, which caused millions of deaths and significantly altered the course of history. A pandemic is a disease occurring in epidemic form throughout the entire population of a country, a people, or the world. Although the cause of the plague was not identified until the third pandemic in 1894, scientists are virtually certain that th…
Treatment
- Untreated pneumonic plague can be rapidly fatal, so early diagnosis and treatment is essential for survival and reduction of complications. Antibiotics and supportive therapy are effective against plague if patients are diagnosed in time. Pneumonic plague can be fatal within 18 to 24 hours of disease onset if left untreated, but common antibiotics for enterobacteria (gram negative rods) …
- Due to the clinical severity of the disease, doctors will usually start treatment presumptively while awaiting lab results. Ideally, treatment should be started within 24 hours, usually in the form of intravenous antibiotics such as streptomycin, doxycycline, or tetracycline. If treated in a timely manner, survival rates can range from 85 percent to as high as 99 percent.
- As soon as your doctor suspects that you have plague, you'll need to be admitted to a hospital. You'll receive powerful antibiotics, such as: 1. Gentamicin 2. Doxycycline (Monodox, Vibramycin, others) 3. Ciprofloxacin (Cipro) 4. Levofloxacin 5. Moxifloxacin (Avelox) 6. Chloramphenicol...
- 1. Streptomycin is the treatment of choice, but is difficult to obtain. Alternatives include: 1. Gentamicin (2-3 mg/kg tid, IM or SQ) 2. Doxycycline (5 mg/kg bid, PO) 3. Tetracycline (22 mg/kg tid, PO) 4. Chloramphenicol (50 mg/kg bid, PO) 2. Parenteral antibiotics may be switched to oral therapy upon clinical improvement.
Symptoms
- People infected with plague usually develop acute febrile disease with other non-specific systemic symptoms after an incubation period of one to seven days, such as sudden onset of fever, chills, head and body aches, and weakness, vomiting and nausea. There are two main forms of plague infection, depending on the route of infection: bubonic and pneumonic. 1. Bubonic pla…
- When a human is infected with the bacteria called Y. pestis, it travels through the lymphatic system and ends up in the lymph nodes where it causes painful, boil-like enlargements called buboes. This typically happens within one to seven days of exposure and can be accompanied by a number of symptoms including: The route of the disease can vary in persons infected by Y. pe…
- Fleas carry the bacterium Yersinia pestis, formerly known as Pasteurella pestis. The plague bacillus can be stained with Giemsa stain and typically looks like a safety pin under the microscope. When a flea bites an infected rodent, it swallows the plague bacteria. The bacteria are passed on when the fleas, in turn, bite a human. Interestingly, the plague bacterium grows in …
Prevention
- Preventive measures include informing people when zoonotic plague is present in their environment and advising them to take precautions against flea bites and not to handle animal carcasses. Generally people should be advised to avoid direct contact with infected body fluids and tissues. When handling potentially infected patients and collecting specimens, standard pre…
- The key to the prevention of bubonic plague is the avoidance of rodents or any wild animal that can carry fleas. It also requires you to safeguard your property from things that attract animals, like open waste containers or unfenced gardens. There are precautions to take for the prevention of bubonic plague, especially if you live in an area where flea infestations are common. If traveli…
- It is important that public health officials be notified promptly when plague is suspected in a cat. 1. Public health officials will assist with follow-up investigations and implementation of preventive measures at sites where cats might have been exposed to minimize future risk. 2. Follow-up will help identify persons who might have been exposed to the infected animal so that appropriate p…
- Anyone who has come in contact with a plague pneumonia victim should be given antibiotics, since untreated pneumonic plague patients can pass on their illness to close contacts throughout the course of the illness. All plague patients should be isolated for 48 hours after antibiotic treatment begins. Pneumonic plague patients should be completely isolated until sputum cultur…
Prognosis
- Without treatment, the bubonic plague will result in death in 60 percent to 90 percent of cases, usually within 10 days.
- Plague can be treated successfully if it is caught early; the mortality rate for treated disease is 1-15% but 40-60% in untreated cases. Untreated pneumonic plague is almost always fatal, however, and the chances of survival are very low unless specific antibiotic treatment is started within 15-18 hours after symptoms appear. The presence of plague bacteria in a blood smear is a grave si…
Definition
- Plague is a serious, potentially life-threatening infectious disease that is usually transmitted to humans by the bites of rodent fleas. It was one of the scourges of early human history. There are three major forms of the disease: bubonic, septicemic, and pneumonic.
Diagnosis
- Bubonic plague is diagnosed by running lab cultures on sputum, blood, spinal fluid, or infected lymph nodes. In parts of the world where the plague is more commonly seen, a rapid dipstick test can usually identify bacterial antigens within 15 minutes.
- If your doctor suspects plague, he or she may look for the Yersinia pestis bacteria in samples taken from your: 1. Buboes. If you have the swollen lymph nodes (buboes) typical of bubonic plague, your doctor may use a needle to take a fluid sample from them (aspiration). 2. Blood. You'll generally have Yersinia pestis bacteria present in your bloodstream only if you have septic…
- Plague should be suspected if there are painful buboes, fever, exhaustion, and a history of possible exposure to rodents, rabbits, or fleas in the West or Southwest. The patient should be isolated. Chest x rays are taken, as well as blood cultures, antigen testing, and examination of lymph node specimens. Blood cultures should be taken 30 minutes apart, before treatment.A gr…
Epidemiology
Background
- Cats are highly susceptible to plague and are a common source of Yersinia pestis infection in humans (owners and veterinarians). Dogs infected with plague are less likely to develop clinical illness than cats.Most cases of plague in cats present with a sub-mandibular lymphadenitis. Abscessed lymph nodes may be clinically indistinguishable from abscesses due to other causes…
