Due to the particularities of hospitals, their environment contains a large number of microorganisms, providing very favorable conditions for the reproduction and spread of pathogenic microorganisms. On the other hand, as an important site of antibiotic use, hospital-associated infections and antimicrobial resistance mutually promote the formation of a vicious circle. There is strong evidence that airborne and aerosol transmission of pathogenic microorganisms is widespread in hospital settings. In that sense, airborne particles are characterized by their low density, invisibility, and susceptibility to turbulence. The settling of airborne infectious particles on a patient's wound can cause infections in surgery or, in more serious cases, infect patients with compromised immune systems, or can lead, if ventilation conditions are not appropriate, to the spread of pathogens. bacteria and fungi (bioaerosols) from infectious patients to the entire hospital community. To improve the status of these hospital-associated infections, traditional systems have focused on strategies to eliminate pathogens present in patients, clinical surfaces, and healthcare workers, which has prompted the implementation of various infection control and disinfection protocols that they have also been successful in reducing the incidence of this type of hospital infection. Within these procedures, there is the use of a ventilation system with positive or negative air pressure. The objective of this work is to determine the microbial control capacity of the ventilation systems in two medical care centers in Peru in rooms with immunosuppressed patients (HIV/AIDS) isolated or in infectious patient rooms.
