This case report used a button sampler , <*> for environmental sampling around a child
none of the air samples contained any detectable adenovirus DNA
This case report used a button sampler , worn or held by staff or left free - standing in a fixed location , for environmental sampling around a child who was chronically infected by a respiratory adenovirus , to determine whether there was any risk of secondary adenovirus infection to the staff managing the patient .
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 .
