Nosocomial infections, also known as hospital-acquired infections (HAIs), are infections that patients acquire while receiving treatment for other conditions within a healthcare setting. These infections typically occur 48 hours or more after hospital admission or within 30 days after receiving healthcare services. Common types of nosocomial infections include urinary tract infections, surgical site infections, pneumonia, and bloodstream infections. They are often caused by pathogens such as bacteria, viruses, and fungi, with Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa being frequent culprits. The spread of these infections is facilitated by several factors, including the invasive procedures performed on patients, the use of medical devices such as catheters and ventilators, and the high density of susceptible individuals in hospitals. Additionally, the overuse and misuse of antibiotics have contributed to the emergence of antibiotic-resistant strains, complicating treatment efforts.

Nosocomial infections pose significant challenges to healthcare systems due to their impact on patient morbidity, mortality, and healthcare costs. They can lead to prolonged hospital stays, additional diagnostic and therapeutic interventions, and increased financial burdens on both patients and healthcare facilities. Preventing these infections requires a multifaceted approach that includes strict adherence to infection control practices, such as hand hygiene, sterilization of medical equipment, and the use of personal protective equipment (PPE). Healthcare workers play a crucial role in preventing the transmission of pathogens by following established protocols and maintaining a clean and safe environment. Surveillance systems to monitor infection rates and identify outbreaks are also essential for prompt intervention and control. Education and training programs for healthcare providers about infection prevention strategies are critical in reducing the incidence of nosocomial infections. Ultimately, a comprehensive and proactive approach involving healthcare professionals, patients, and the healthcare system is necessary to effectively combat nosocomial infections and improve patient safety.

3. Examples of Nosocomial infection nosocomial infections include: ventilator-associated pneumonia, , Candida albicans, , Clostridium difficile, Tuberculosis, Urinary tract infection, a nd Legionnaires' disease .

4. R i s k Factors that increase the risk for a nosocomial infection include increasing age, length of hospitalization, excessive or improper use of broad-spectrum antibiotics, and the number of invasive devices and procedures (for instance: central venous catheters, urinary catheters, surgical procedures, and mechanical ventilation). In addition, most patients h ave conditions such as diabetes, chronic lung disease, renal insufficiency, or malnutrition .

5. The symptoms for these infections may include: discharge from a wound. fever. cough, shortness of breathing. burning with urination or difficulty urinating. headache. nausea, vomiting, diarrhea .

6. Causes: N socomial infections are caused by multidrug-resistant pathoge n b a cteria, viruses, and fungi can all cause nosocomial infections, the most common is the bacterium Staphylococcus aureus. Other common pathogens like Escherichia coli, Enterococci, and all can be normally found on the skin and mucous membranes

7. Prevention: M e t h o d s for preventing nosocomial infection Hand washing: as often as possible. use of alcoholic hand spray. ... Stethoscope : cleaning with an alcohol swab at least daily. Gloves : supplement rather than replace hand washing. Intravenous catheter: thorough disinfection of skin before insertion
