[Viral nosocomial infections: the problem of contemporary hospital management]

Area of Science:

• Infectious Diseases
• Virology
• Hospital Epidemiology

Background:

• Nosocomial infections pose a significant threat in healthcare settings.
• Viral pathogens are a major cause of hospital-acquired infections, impacting various organ systems.

Purpose of the Study:

• To present the most frequent viral pathogens responsible for nosocomial infections.
• To categorize viruses based on the affected organ system (respiratory, digestive, blood-transmitted).

Main Methods:

• Literature review and synthesis of existing data on nosocomial viral infections.
• Classification of viral agents based on clinical manifestations and transmission routes.

Main Results:

• Influenza, parainfluenza, and Respiratory Syncytial (RS) virus frequently cause respiratory tract infections.
• Enteric viruses (rotaviruses, adenoviruses, astroviruses, etc.) are associated with digestive disorders.
• Hepatitis B, C, D, Human Immunodeficiency Virus (HIV), Cytomegalovirus (CMV), and Epstein-Barr Virus (EBV) are transmitted via blood.

Conclusions:

• Understanding the spectrum of nosocomial viral pathogens is crucial for infection control.
• Different viral groups target specific organ systems, necessitating tailored prevention strategies.
• Blood-borne viral infections represent a critical transmission risk in healthcare environments.
