Nosocomial infections are infections acquired in a hospital setting, often spread by hands of healthcare workers or contaminated equipment. Staphylococcus aureus is a classic cause because it commonly colonizes the skin and nasal passages, making transmission in clinical environments frequent. It drives many hospital-associated infections, including surgical site infections, catheter-related bloodstream infections, and pneumonia in ventilated patients. Its ability to form biofilms on catheters and implants helps it persist and resist treatment. The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals further underscores its notoriety, as resistant strains can spread and cause outbreaks more easily. While other organisms can cause hospital infections, Staphylococcus aureus is especially emblematic of nosocomial disease.
