What infections are acquired in the hospital?

• A. Nosocomial Infections
• B. Community-Acquired Infections
• C. Zoonotic Infections
• D. Occupational Infections

Answer: (A)

Infections acquired in the hospital are known as nosocomial infections. These develop after a patient has been admitted and were not present or incubating at the time of admission, typically showing up after about 48 hours in the hospital. The hospital setting—with invasive devices, surgeries, and close contact among patients and staff—facilitates transmission of infections, leading to issues like urinary tract infections from catheters, bloodstream infections from IV lines, pneumonia in ventilated patients, and surgical site infections. Other terms describe different contexts (infections present on arrival or acquired through animal exposure or work), but when the question asks about infections tied to the hospital stay, the correct label is nosocomial infections.
