none of the air samples contained any detectable adenovirus DNA
it is still unclear what level of specific pathogen RNA / DNA constitutes a true clinical risk .
Despite multiple air samples taken on difference days , coinciding with high levels of adenovirus detectable in the child 's nasopharyngeal aspirates ( NPAs ) , none of the air samples contained any detectable adenovirus DNA using a clinically validated diagnostic polymerase chain reaction ( PCR ) assay .
Although highly sensitive , in - house PCR assays have been developed to detect airborne pathogen RNA / DNA , it is still unclear what level of specific pathogen RNA / DNA constitutes a true clinical risk .
