Smallpox

Smallpox was an infectious disease caused by a virus. It could spread easily from one person to another, often through close contact or things that were touched by someone who was sick.

People who got smallpox would first feel very tired and have a fever. Later, they might get sores inside their mouths and a rash on their skin that turned into fluid-filled blisters. These blisters would dry up and fall off, sometimes leaving marks on the skin.

Smallpox has been around for thousands of years. People in ancient Egypt and other places knew about it. It caused many problems for a long time. But the good news is that scientists and doctors worked very hard to stop it.

A man named Edward Jenner created a special vaccine in 1796. This vaccine helped people’s bodies learn to fight the disease. Thanks to this and other efforts, the World Health Organization announced in 1980 that smallpox was gone forever. Today, only a few safe samples of the virus are kept in special laboratories.

Smallpox was a serious disease, but it no longer makes people sick. This is a big success for science and helps keep everyone healthy.
