Pestilence facts for kids
Pestilence is an old word for a very serious and widespread disease. It describes illnesses that spread quickly and affect many people. Think of it as a big sickness that can cause a lot of harm. Sometimes, it can even refer to parasites that cause widespread illness or death, like the Guinea worm.
The word "pestilence" comes from the Latin word pestis, which meant plague. It was often used to describe the terrible Black Death, a huge sickness in the 14th century that killed millions of people across Europe.

Understanding Infectious Diseases
An infectious disease is an illness caused by tiny living things called germs. These germs can be bacteria, viruses, fungi, or parasites. They can enter your body and make you sick. Some common infectious diseases include the flu or the common cold.
How Germs Spread Illness
Germs can spread in many ways. They might travel through the air when someone coughs or sneezes. You can also pick them up by touching surfaces that have germs on them, then touching your face. Sometimes, germs spread through contaminated food or water, or even from animals or insects.
Protecting Yourself from Germs
Washing your hands often with soap and water is a great way to stop germs. Avoiding touching your face, especially your eyes, nose, and mouth, also helps. Getting vaccines for certain diseases can protect you too. These simple steps help keep you healthy and stop germs from spreading.
Epidemics and Pandemics: What's the Difference?
When an infectious disease spreads quickly and affects many people in one area, it's called an epidemic. Imagine a flu outbreak that makes lots of students sick in your school or town. That's an epidemic.
When an Epidemic Becomes a Pandemic
A pandemic is like an epidemic, but much bigger. It happens when a disease spreads across many countries or even continents. The Black Death was a pandemic because it affected almost all of Europe and parts of Asia. A pandemic means the disease is global.
Why Some Diseases Become Pandemics
Diseases can become pandemics if they are very contagious and can travel easily. Modern travel, like airplanes, can help germs move quickly around the world. When a new germ appears that people have no natural protection against, it can spread widely.
The Black Death: A Famous Pestilence
One of the most famous examples of a pestilence is the Black Death. This terrible plague swept through Europe and Asia in the mid-14th century, from about 1346 to 1353. It was caused by a type of bacteria called Yersinia pestis.
Impact of the Black Death
The Black Death was one of the deadliest pandemics in human history. It's estimated that it killed between 75 million and 200 million people. In some parts of Europe, it wiped out half of the population or more. This event changed societies, economies, and even art and culture for many years.
How the Black Death Spread
The bacteria that caused the Black Death lived in fleas, which were carried by rats. When infected rats died, the fleas would jump onto humans and bite them, spreading the disease. The disease also spread directly from person to person through the air.
