What Is Plague?
The plague is an uncommon illness. The disease primarily affects a small number of nations worldwide. Each year, a small number of people in rural or semirural areas of western states in the United States are afflicted by plague. Plague is contracted from the bacterium Yersinia pestis. The plague is a zoonotic disease, meaning that both humans and animals can contract it from one another. Fleas that have previously bitten an infected animal are typically the ones that spread this disease.
The type of condition you have is determined by the site where Y. pestis ends up in your body. Pneumonic plague damages your lungs, septicemic plague affects your blood, and bubonic plague infects your lymph nodes. Antibiotics are typically effective in treating plague. The disease is frequently fatal if left untreated. Plague is also considered a possible biological weapon.
What Are the Types and Symptoms of Plagues?
The following are the types of plague:
Bubonic plague
Lymph node swelling is a result of bubonic plague, also known as the Black Death. The body's immune system contains these tiny, bean-shaped filters. A bubo is a swollen lymph node. This aspect of the illness is referred to as bubonic. A person with bubonic plague will have buboes in their neck, groin, or armpits. Buboes can be painful or tender. Their sizes range from less than half an inch to several inches.
Additional signs of bubonic plague could be:
-
Sudden chills and a high fever.
-
A headache.
-
Fatigue.
-
Weakness.
-
Aches in the muscles.
-
Skin sores are uncommon.
Septicemic plague
Septicemic plague may develop from untreated bubonic plague or may be the initial sign of plague. This form is caused by handling an infected animal or by flea bites. Although it is not well defined, the incubation period of septicemic plague most likely lasts for a few days after exposure.
When plague bacteria proliferate in the bloodstream, septicemia of plague results. There might not be any buboes.
Early signs are quite widespread and consist of:
-
Sudden chills and a high fever.
-
Utter weakness.
-
Vomiting.
-
Diarrhea (loose stool).
-
Stomach pain.
With organ failure and advanced disease, more severe symptoms could appear. Among them are:
-
Bleeding from beneath the skin or from the mouth, nose, or rectum.
-
Shock symptoms include low blood pressure, rash, and seizures.
-
Usually found on the fingers, toes, ears, and nose, gangrene is a blackening and death of tissue.
Pneumonic plague
When bacteria enter a patient's lungs from untreated bubonic or septicemic plague, or when an infected person inhales infectious droplets coughed out by another person or animal with pneumonic plague, pneumonic plague develops. The only kind of plague that can spread from person to person is pneumonic plague, which is also the most dangerous.
The lungs are impacted by pneumonic plague. The illness may start in the lungs or spread to the lungs from infected lymph nodes. After exposure, symptoms may appear a few hours later and get worse quickly.
Symptoms could consist of:
-
Sudden chills and a high fever.
-
Coughed up bloody mucus.
-
Breathing problems or irregularities.
-
Chest discomfort.
-
Vomiting and stomach upset.
-
Headache.
-
Weakness.
How Is Plague Diagnosed?
To diagnose plague, your doctor may draw blood, mucus, or phlegm from your sputum or fluid from a lymph node to check for the Y. pestis bacteria and diagnose plague. A swollen, painful lymph gland known as a bubo is the most typical symptom of bubonic plague. If you have a bubo or flea bite, your doctor might suspect plague.
Be sure to inform your provider if you:
-
Reside in or have recently traveled to a region where plague is prevalent.
-
Have had flea bites.
-
Handled potentially infected animals.
-
Possess a lymph node or nodes that hurt.
What Tests Are Done to Diagnose Plague?
The following are the tests to be done to diagnose plague:
-
Lymph node aspirate: A contaminated bubo usually has an organism that can be examined under a microscope and cultured.
-
Blood: A sensitive way to find Y. pestis is through routine blood cultures. When bacteremia levels are high enough in the later stages of the disease, organisms may occasionally be visible under a microscope on blood smears.
-
Respiratory specimens: Blood is typically culture positive at this time as well, but sputum from very sick patients with pneumonic plague can also be cultured.
-
Biopsy: A specimen from the liver, lung, spleen, or lymphoid tissue can be biopsied or undergo autopsy.
What Causes Plague, and How Does Plague Spread?
The plague-causing bacterium, Yersinia pestis, can infect humans through animals or other people. Humans can also be infected by air through infected droplets. Additionally, animals can contract the plague from other animals, too.
Plague in humans: The most common way for people to contract plague is through flea bites. Pets or small wild animals are most likely the source of the fleas. Direct contact with an infected animal's tissues can also infect humans with the plague. Either humans or animals can contract pneumonic plague; when an animal or person coughs or sneezes, tiny droplets of bacteria may be released into the air. Inhaling these droplets or touching coughed-up mucus can infect a person.
Is Plague Contagious?
Pneumonic plague can spread, but bubonic and septicemic plague cannot. Through coughing, sneezing, and close contact, pneumonic plague can be transmitted from one person to another.
How to Prevent Plague?
One can prevent plague by using the following measures:
-
By avoiding flea bites and exercising caution around potentially infected animals, you can lower your risk of contracting plague.
-
Clear away any trash, wood, brush, or other areas where wild animals could hide. Do not feed wild animals or leave pet food out.
-
Use DEET-containing (N, N-diethyl-meta-toluamide) bug repellent.
-
Cats and dogs kept as pets may transmit the plague.
-
If you need to work with potentially infected animals, put on gloves. This covers both living and deceased animals.
-
Do not let your pets run loose outside if you live in a plague-affected area.
-
Consult your doctor about taking antibiotics to avoid contracting the plague if you suspect you were exposed to it.
How Is Plague Treated?
Antibiotics must be administered immediately to treat the plague. Your physician will administer medication to you either intravenously (IV) or as a pill. You might be asked to begin the antibiotics before your doctor receives your test results, depending on your symptoms and risk.
What Medications Are Used to Treat Plague?
Antibiotics are administered orally or intravenously to treat plague. Your doctor may recommend one or more of the following antibiotics:
-
Ciprofloxacin.
-
Levofloxacin.
-
Doxifloxacin.
-
Doxycycline.
-
Gentamicin.
-
Streptomycin.
-
Chloramphenicol.
-
Sulfamethoxazole and Trimethoprim.
Conclusion
The bacterium Yersinia pestis causes the potentially fatal plague. In the history of plague, millions of Europeans between the ages of 40 and 60 were affected by it. These days, it is an uncommon but enduring cause of disease in rural regions. Antibiotics can treat plague, but they must be administered quickly to avoid severe illness or death. Approximately 90 percent of patients with all types of plague survive with prompt treatment.
Key Takeaway
Plague is an uncommon illness. Every year, a small number of people in rural or semirural areas of western states in the United States are afflicted by plague. Antibiotics can typically be used to treat plague. Avoiding flea bites and exercising caution around potentially infected animals can lower your risk of contracting the plague.
