Detection of airborne viruses in a pediatrics department measured using real-time qPCR coupled to an air-sampling...

Area of Science:

• Environmental microbiology
• Pediatric infectious diseases
• Molecular diagnostics

Background:

• Children are particularly susceptible to viral infections.
• Understanding viral transmission routes in pediatric healthcare settings is crucial for infection control.
• Aerosol transmission poses a significant risk in environments with vulnerable populations.

Purpose of the Study:

• To investigate the presence and types of airborne viruses in a pediatric emergency room.
• To evaluate the efficacy of filtration and real-time quantitative polymerase chain reaction (qPCR) for detecting viral aerosols.
• To assess the potential for aerosol transmission of common pediatric respiratory viruses.

Main Methods:

• Collection of viral aerosols using a filtration method from the pediatric emergency room.
• Detection and quantification of influenza A virus (INFAV), human adenovirus (HAdV), and enterovirus using real-time qPCR.
• Analysis of 33 aerosol samples for viral presence and load.

Main Results:

• Influenza A virus (INFAV) was detected in 24% of samples, human adenovirus (HAdV) in 36%, and enterovirus in 15%.
• Human adenovirus (HAdV) was the most frequently detected virus in aerosols.
• Enteroviruses exhibited the highest viral titer among the detected viruses.

Conclusions:

• The filter/real-time qPCR assay is effective for measuring viral aerosols in occupational settings.
• Environmental monitoring of airborne viruses can serve as an early warning system for potential hospital-acquired infections.
• Findings underscore the importance of controlling airborne viral transmission in pediatric healthcare environments.
