Antibiotics: A Simple Definition for 7th Graders

Antibiotics are powerful medicines that fight certain infections caused by bacteria in humans and animals. These drugs work by either killing the bacteria or stopping them from reproducing, which helps the body's immune system overcome the infection. Antibiotics are prescribed by doctors to treat a wide range of bacterial illnesses, from common infections like strep throat to more serious conditions like pneumonia.

It's important to understand that antibiotics only work against bacteria and are not effective against viruses, which cause illnesses like the common cold or flu. Antibiotics come in various forms, including pills, liquids, creams, and injections. When taking antibiotics, it's crucial to follow the doctor's instructions carefully and finish the entire course of medication, even if you start feeling better before it's done.

While antibiotics have saved countless lives since their discovery, using them too often or incorrectly can lead to a problem called antibiotic resistance. This occurs when bacteria change over time and become able to survive the effects of antibiotics, making these medicines less effective in treating infections. To prevent this, antibiotics should only be used when necessary and as directed by a healthcare professional.

Antibiotics have revolutionized medicine by making it possible to treat many once-deadly infections. However, they are not a cure-all and should be used responsibly to ensure they remain effective for future generations. Understanding what antibiotics are and how they work is an important part of maintaining good health and contributing to global efforts to combat antibiotic resistance.
