Antibiotics are special drugs used to treat infections caused by bacteria. Thanks to antibiotics, doctors can perform all kinds of modern treatments and operations that would otherwise be very risky; think, for example, hip surgery or cancer treatment. But there is a problem: bacteria are incredibly smart, and can adapt so that antibiotics no longer work: they become resistant. The more we use antibiotics, the more likely bacteria are to become resistant. To ensure that antibiotics do not lose their power, it is important that we use them wisely. In the antibiotics game, you will learn more about how antibiotics work, how to use them properly, and why bacteria can sometimes become resistant to antibiotics.
