Anti-infectives

🛡️ What are Anti-Infectives?

Anti-infectives are medications used to prevent or treat infections caused by bacteria, viruses, fungi, or parasites.

They are essential in fighting infectious diseases, which can affect any part of the body — from the lungs to the skin, blood, or gastrointestinal system.

🧫 Main Classes of Anti-Infectives

💊 Type⚡ Target Organism📋 Examples
