Bubonic plague: overview, symptoms and causes

Overview of bubonic plague

The plague is a dangerous bacterial infection spread predominantly by fleas. Yersinia pestis, the organism that causes plague, reside in small rodents found in village and semi-rural areas of Africa, Asia, and the United States. Humans are contaminated when they are stung by fleas that have eaten infected rodents or when they handle infected animals. One kind of plague is bubonic plague (black death). It’s named after the disease’s swollen lymph nodes (buboes). The nodes in the axilla, groin area, and neck can swell and ooze pus and become as large as eggs. The following are some of the other plagues:

• When an infection spreads throughout the body, it is called the septicaemic plague.
• When the lungs are infected, it causes pneumonic plague.

Although most people that got the plague died, and many had blackened tissue because of gangrene, it was called the Black Death.

History of Black Death

The epidemic killed around 25 million individuals in the 14th century. This was almost two-thirds of the European population. Rats carried fleas and plague on ships. The Black Death was so named because most plague victims died and many had gangrene-blackened tissue. There was no way to get rid of the plague.
Aside from the Black Death, there have been numerous outbreaks of bubonic plague (1346-1353). There are still cases of the black death in Africa, Asia, South America, and western North America. Every year, the US sees around seven cases of plague. People aged 12 to 45 make up half of the US cases.
North-central New Mexico, northern Arizona, and southern Colorado have the highest plague cases in the US, followed by Southern Oregon and western Nevada.

Bubonic Plague Causes:

The Yersinia pestis (Y. pestis) bacterium causes black death, which is spread primarily by fleas on rodents and other animals. Humans who are stung by fleas can become infected with the plague. It’s an example of a disease that can be passed from animals to humans known as a zoonotic disease. Overcrowding, poor sanitary conditions, and an increased rodent population are all factors that contribute to plague flare-ups in rural and semi-rural regions. Human plague infections are most common in Africa, particularly on the African island of Madagascar. Humans have also been infected with bubonic plague symptoms in parts of Asia and South America.

The plague is caused by flea bites from infected animals, such as:
Rats, Mice, Cats, Squirrels, Prairie dogs, Rabbits, Chipmunks, Voles
Dogs and cats that live at home can get plague if they get flea bites or eat infected rodents. Cats, in particular, are susceptible to plague and can become infected by consuming severely ill rodents. These cats can transmit plague-infected droplets to their owners. Except in rare cases of someone with pneumonic plague (infected lungs) spreading plague through droplets sprayed into the air, the human-to-human spread is doubtful.

Black Death Symptoms:

Bubonic plague symptoms are the most common. As soon as you get sick, your lymph nodes (buboes) swell up.
Bubonic plague symptoms include:

• High fever and chills all of a sudden.
• Aches and pains in the abdomen, arms, and legs.
• Headaches.
• Large, swollen lumps (buboes) develop in the lymph nodes and drain pus.

Septicaemic plague can cause blackened tissue from necrosis, which usually affects the fingers and toes, as well as unexpected bleeding. Pneumonic plague patients may have more difficulty breathing and cough up blood. bubonic plague symptoms such as nausea and vomiting can occur.

Diagnosis of Black Death

After finding Yersinia pestis in blood or tissue from the person who has the disease, to diagnose bubonic plague symptoms. This could be done by taking an aspirate from an enlarged lymph node, for example. A lot of diagnostic tests use things like growing the organism, showing the bacteria’s surface proteins, or finding the bacteria’s genetic material to figure out what is going on. Tests that can show how the body’s immune system is reacting to the infection are also out there.

Treatment of Black Death

Antibiotics work well against bubonic plague symptoms. Antibiotics include ciprofloxacin (Cipro, Cipro XR, Proquin XR), streptomycin, gentamicin (Garamycin), and doxycycline can be utilised (Vibramycin, Oracea, Adoxa, Atridox). Patients with plague may require additional treatment such as oxygen, respiratory support, and blood pressure drugs. To prevent the spread of pneumonic plague, patients must be segregated.

Prevention from Black Plague:

If you don’t treat the black death, it can be fatal. It can spread disease all over your body (septicemic plague) and/or get into your lungs (pneumonic plague.) Septicemic and pneumonic plague both die if they don’t get treated.

To avoid the black death, take the following precautions:

• Make your home and yard uninhabitable for rodents (mice, rats, and squirrels), as well as other wild animals. Don’t leave any hiding spots or food for them to eat. Cleaning up clutter, brush, and other items, as well as being cautious when feeding animals, are all part of this.
• Flea control products should be used on your pets, particularly those that are allowed to roam freely. Take sick pets to the vet as soon as possible.
• Allowing roaming pets to sleep in your bed is not a good idea.
• If you work with dead animals, wear protective clothing, especially gloves.
• If you go into wooded areas or other places where you might be exposed to fleas, use insect repellent. Look for repellents that are safe to use.
