Antibiotics are essential medicines designed to fight bacterial infections. Since their discovery, they have been responsible for saving millions of lives and making many medical procedures safer. However, the effectiveness of these drugs is now threatened by a global problem known as antibiotic resistance. This phenomenon occurs when bacteria change over time and develop the ability to defeat the drugs designed to kill them. The main driver of this resistance is the overuse and misuse of antibiotics. For instance, taking antibiotics for a viral infection, such as the flu, is a common mistake because these medicines do not work on viruses. In addition, when patients fail to complete the full prescribed course of treatment, some of the strongest bacteria can survive. These survivors then multiply and pass on their resistant traits. As a result, infections that were once simple to cure are becoming a significant public health challenge. Therefore, responsible use of antibiotics is crucial to maintain their effectiveness for the future.
