A subset of infectious disorders obtained in a health-care facility is known as nosocomial infections, sometimes known as health-care-associated or hospital-acquired infections. The infection cannot be present at the time of admission; rather, it must develop at least 48 hours after admission to be deemed nosocomial. These infections can cause major complications such as sepsis and even death. The intensive care unit (ICU), where doctors treat critical disorders, is one of the most common wards where HAIs arise. A HAI affects about one out of every ten persons hospitalised to a hospital. They're also linked to high rates of morbidity, mortality, and hospitalisation. Infection control strategies, monitoring antimicrobial use and resistance, and implementing antibiotic control policies can all help to prevent nosocomial infections. At both the national and international levels, an effective surveillance system can help. To prevent and control nosocomial infections, all stakeholders must work together.
