What Is the Plague?

You might assume that the plague, historically known as the Black Death, is a relic of the past, vanishing alongside knights in armor and medieval village life. However, this ancient scourge, which once swept across the world with deadly consequences, still lingers among us. The disease that plagued our ancestors has not gone extinct; it remains a persistent threat, though we now have a much deeper understanding of its causes and a vital weapon in the form of effective treatments.

The Basics of Plague

The plague is a bacterial infection caused by Yersinia pestis, and it is primarily transmitted by fleas. These microscopic hitchhikers acquire the bacterium when they bite infected animals, such as rats, mice, or squirrels. Subsequently, when these fleas bite other animals or humans, they transmit the plague. Direct transmission from infected animals or individuals is also possible.

Thanks to our advancements in treatment and prevention, the plague has become rare in the modern world. Fewer than a few thousand people worldwide contract the disease each year, with the majority of cases occurring in regions like Africa (notably the Democratic Republic of Congo and Madagascar), India, and Peru.

In the United States, approximately seven cases of the plague are reported annually, predominantly in rural or remote areas of Southwestern states, including Arizona, Colorado, New Mexico, and California.

Recognizing the Symptoms

The onset of plague symptoms typically occurs 1 to 6 days after initial exposure. Infected individuals experience severe weakness, accompanied by fever, chills, and headaches. The specific symptoms, however, depend on the three primary types of plague:

1. Bubonic Plague: This is the most prevalent form, characterized by the development of painful, swollen lymph nodes known as buboes. These can emerge under the arms, in the neck, or in the groin. Without prompt treatment, the bacteria can disseminate to other parts of the body.

2. Septicemic Plague: This variant is more perilous than bubonic plague, signifying that the bacteria have entered the bloodstream. Symptoms include:

  • Bleeding beneath the skin or from the mouth, nose, or rectum
  • Darkened or blackened skin, particularly affecting the nose, fingers, and toes
  • Abdominal pain, diarrhea, vomiting, and signs of shock

3. Pneumonic Plague: The bacteria in this form of the plague primarily affect the lungs, making it the rarest yet most lethal version. Pneumonic plague is highly contagious, as it can spread through the air when an infected person coughs. Symptoms include:

  • Coughing, occasionally with blood
  • Difficulty in breathing
  • Nausea, vomiting

Who Is at Risk?

For most individuals, the risk of contracting the plague is relatively low. However, there are specific circumstances that elevate the likelihood of infection. You are more likely to be exposed to the plague if you:

  • Come into contact with living or deceased animals that may have been infected, such as rats, mice, squirrels, rabbits, or chipmunks.
  • Work regularly with animals.
  • Spend an extended period outdoors, engaging in activities such as labor, hiking, camping, or hunting.
  • Have been in proximity to someone who has contracted the plague.

Treatment: A Race Against Time

If you suspect you have been exposed to the plague and are displaying symptoms, it is imperative to seek immediate medical attention. Time can be the critical factor in recovery. Your doctor will perform tests, which may include the examination of blood, saliva, or lymph node fluid, to detect plague bacteria.

In some cases, especially if you have been in contact with someone infected with the plague, your doctor may commence treatment even before you exhibit symptoms. In situations where you must be near an infected individual, it is advisable to wear tight-fitting disposable surgical masks to prevent inhalation of plague bacteria.

For those diagnosed with the plague, hospitalization is necessary. Treatment primarily involves the administration of antibiotics. The following antibiotics are typically used:

  • Ciprofloxacin (Cipro)
  • Doxycycline (Vibramycin)
  • Gentamicin (Garamycin)
  • Levofloxacin (Levaquin)

The good news is that the treatment is highly effective. With the use of antibiotics, most individuals recover within a week or two. However, without treatment, the mortality rate for those infected with the plague is alarmingly high.

Preventing Plague: No Vaccination, but Vigilance Is Key

In the United States, there is currently no vaccine available for the plague. Therefore, taking preventive measures to reduce the risk of exposure becomes crucial.

If you are traveling to regions in Africa, Asia, or South America, it is advisable to check for traveler advisories concerning plague outbreaks on the CDC website. Avoid areas with a history of plague if possible, and steer clear of sick or deceased animals during your stay.

For those residing in regions where the plague has been documented:

  • Seal any openings and gaps in your home that could allow mice, rats, and squirrels to enter.
  • Maintain a clean yard by eliminating piles of leaves, wood, and rocks, which can serve as potential habitats for animals.
  • When engaging in outdoor activities such as hiking or camping, use insect repellent containing DEET to prevent flea bites.
  • Always wear gloves when handling wild animals, whether they are alive or deceased.
  • Utilize flea control sprays or other treatments on your pets.
  • Avoid allowing outdoor pets, such as cats or dogs, to sleep in your bed.

In conclusion, the plague, once the terrifying scourge known as the Black Death, still exists today but has become increasingly rare thanks to advancements in our understanding of the disease and the availability of effective treatments. By recognizing the symptoms, understanding who is at risk, and adopting preventive measures, individuals can take control of their health and reduce the chances of encountering this centuries-old foe. While the plague remains a formidable adversary, knowledge and vigilance are our strongest allies in the ongoing battle against this ancient and potentially deadly disease.
