What type of medications are used to treat bacterial infections?

The correct answer is antibiotics, which are specifically designed to treat bacterial infections. Antibiotics work by targeting the unique features of bacterial cells, such as their cell walls or specific metabolic pathways, which are not present in human cells. This selective action allows antibiotics to effectively kill or inhibit the growth of bacteria without harming human cells.

In contrast, painkillers primarily relieve discomfort without addressing the underlying infection. Antivirals are utilized to treat infections caused by viruses and target viral replication processes, while antifungals are meant to treat fungal infections. Since each type of medication is tailored to specific pathogens, understanding the role of antibiotics is crucial when addressing bacterial infections.
