Types of Plague Infections
Learn about the different kinds of plague infections and why they matter. Keep reading to discover more.
Pneumonic and Septicemic Plague
Pneumonic plague attacks the lungs and can spread from person to person through coughing. This makes it very dangerous because it can quickly infect large groups of people if not treated fast with antibiotics.
Symptoms appear suddenly and include fever, headache, weakness, and a rapidly developing pneumonia which causes shortness of breath, chest pain, and cough.
Septicemic plague happens when the infection spreads to the blood. Without immediate treatment, it can cause shock and organ failure. Signs of this form include fever, chills, extreme weakness, abdominal pain, shock, and possibly bleeding into the skin or other organs.
Skin and tissue may turn black and die in severe cases.
Bubonic and Pharyngeal Plague
Shifting focus from pneumonic and septicemic plague brings us to bubonic and pharyngeal plague, each presenting unique challenges. Bubonic plague is notorious for its swollen, painful lymph nodes, called buboes.
This form results from the bite of an infected flea and was a key player in the Black Death pandemic. Symptoms appear suddenly and can include fever, chills, headache, and muscle aches.
Pharyngeal plague stems from consuming contaminated meat or inhaling infectious droplets. It targets the throat, leading to severe swelling that can obstruct breathing. Both types underscore Yersinia pestis’s versatility as a pathogen capable of triggering distinct yet equally devastating forms of disease.
Plague Meningitis
Plague meningitis happens when the Yersinia pestis bacteria invade the membranes surrounding the brain and spinal cord. This rare form of plague is a complicated turn in an already serious disease, leading to symptoms like severe headaches, fever, neck stiffness, and confusion.
Patients need quick treatment with strong antibiotics to fight off the infection.
Doctors use blood tests and sometimes take fluid from around the spine to diagnose this condition. The goal is always to start treatment early since delay can lead to severe complications or even death.
For anyone exposed to plague bacteria, getting medical attention fast is critical for preventing meningitis from developing.
Transmission of Plague
Plague spreads from animals to humans, mainly by flea bites. It can also spread from person to person through the air.
Person-to-person
Person-to-person transmission of Yersinia pestis is rare but can occur, particularly in cases of pneumonic plague. If someone with pneumonic plague coughs, the bacteria can spread through droplets in the air.
People nearby may breathe these droplets in and get sick. This form requires quick action to prevent spreading.
Doctors use masks and gloves to protect themselves and others when treating someone with this type of plague. They also tell people to avoid close contact with patients until they are no longer contagious.
Quick treatment with antibiotics can stop the disease from spreading further.
Biological weapon
Moving from the natural transmission of Yersinia pestis, it’s crucial to address its potential as a biological weapon. Yersinia pestis, labeled a category A agent, highlights its significance in bioterrorism threats due to possible bioengineered multi-drug resistance.
