The plague is an infectious disease that affects both people and animals. Although it was once known as the Black Death, a disease that swept the world hundreds of years ago, the plague still exists today and can be dangerous if not treated promptly. In this article, we'll explore the causes, symptoms, and prevention of the plague.
The plague is caused by bacteria called Yersinia pestis. It is usually spread by fleas that pick up the germs when they bite infected animals like rats, mice, or squirrels. These fleas then pass the bacteria to the next animal or person they bite. People can also catch the plague directly from infected animals or other people.
There are three main types of plague:
Bubonic plague: Usually caused by a flea bite, this type of plague causes swollen and painful lymph nodes called buboes.
Septicemic plague: Can be caused by a flea bite or by touching an infected animal. It can also develop from untreated bubonic plague when the bacteria infects the blood.
Pneumonic plague: The most serious type, pneumonic plague can spread from person to person through droplets released when an infected person sneezes or coughs.
Symptoms of the plague typically appear 1-8 days after infection and may include:
Fever
Chills
Headaches
Weakness
Swollen and painful lymph nodes (buboes) in the case of bubonic plague
Bleeding under the skin or from the mouth, nose, or bottom in septicemic plague
Chest pain, coughing (sometimes with blood), and difficulty breathing in pneumonic plague
If you suspect you have the plague, seek medical attention immediately. Your doctor will take samples from your body, such as blood or tissue from a swollen lymph gland, to test for the bacteria that causes the plague. If diagnosed, you'll be admitted to the hospital and given antibiotics like ciprofloxacin, doxycycline, gentamicin, or levofloxacin. With prompt treatment, most people recover within a week or two.
There is no vaccine for the plague in the U.S., so it's essential to take preventive measures if you live in or travel to areas where the plague is present:
Avoid areas with known plague outbreaks
Stay away from sick or dead animals
Use insect repellent with DEET to prevent flea bites
Wear gloves if you must touch wild animals
Use flea control products on your pets
Keep your home and yard free of piles of leaves, wood, and rocks where animals might make their homes
By understanding the causes, symptoms, and prevention of the plague, you can help protect yourself and others from this potentially deadly disease. If you suspect you have been exposed to the plague or experience symptoms, seek medical attention immediately. Early treatment is crucial for a full recovery.
