The most common fungal and viral pathogens associated with nosocomial infections

Background and Aim : Nosocomial infections affect a significant number of patients worldwide and lead to increased mortality and financial impact on health care systems. The present study was designed to determine the most common fungal and viral pathogens associated with nosocomial infections.Methods : The present study was a brief review study designed in ۲۰۲۱. PubMed / Medline and Scopus databases were used to search for similar studies and extract content. Selected keywords for the search included “fungal”, “viral”, “Pathogen” and “nosocomial infection”. The articles were retrieved using advanced search and using AND - OR operators. The one researcher examined the extracted articles and included Latin articles on the fungal and viral pathogens associated with nosocomial infections. Summaries of articles published in congresses and conferences were excluded from the study. Initially, ۱۱ articles were finally evaluated.Results : Fungi are among the most common pathogens in nosocomial infections. Candidia species including C. albicans, C. parapsilosis, and C. glabrata are the most common fungal microorganisms associated with nosocomial infections. Candia auris is also a multidrug-resistant microorganism that is associated with high mortality due to difficulty in diagnosis and high failure rate in treatment. Also, species of Aspergillus, Mucor and Fusarium are involved in nosocomial infections. Among the pathogens, viral infections are the least reported. However, HIV and hepatitis B and C are common in medical and health care centers due to contact with unsafe needles. Rhinovirus, cytomegalovirus, herpes simplex virus, rotavirus, influenza are other common types of viral pathogens associated with nosocomial infections.Conclusion : The results of the present study showed that fungi and viruses are among the most common pathogens associated with nosocomial infections, so the patient environment and medical equipment should be kept clean regularly; The use of safe disposable syringes as well as prophylaxis with antifungal drugs for patients at risk for invasive fungal infections should be considered during periods when the patient has a weakened immune system.
