cord-276997-hbovh7s9	Alsved, Malin	Aerosolization and recovery of viable murine norovirus in an experimental setup	2020-09-29		.txt	text/plain	6031	297	46	However, the infectivity of airborne human noroviruses has not been possible to assess in real-world environments, nor in laboratory experiments, since there is no well-established cell culturing system for these viruses working at the low concentrations obtained in air samples 6 . SLAG: Sparging liquid aerosol generator; HEPA filter: high efficiency particulate air filter; nsRNA: negative sense RNA; psRNA: positive sense RNA; MNV: murine norovirus; qRT-PCR: quantitative reverse transcriptase polymerase chain reaction. Taken together, as compared to the atomizer, a smaller amount of SLAG aerosol is collected by the BioSampler (i.e., higher physical dilution), but these particles contain more MNV psRNA copies (lower viral dilution relative the physical dilution). The experimental setup described here highlights some difficulties in studies on aerosolized viruses: (1) the lack of standards in how to generate bioaerosol that results in significant differences in aerosol particle size and concentration, (2) the necessity to determine both physical and viral dilution factors, and (3) www.nature.com/scientificreports/ during airborne transport due to the low-solute solution and dilution in the setup.	./cache/cord-276997-hbovh7s9.txt	./txt/cord-276997-hbovh7s9.txt
