SecureBio, Inc. @securebio.org · Feb 24 Preprint: We applied untargeted viral metagenomics to composite airplane wastewater and found that human viruses had much higher relative abundance (median 13-fold) compared to municipal treatment-plant wastewater. This could substantially cut costs of using metagenomics to detect emerging viruses.

Higher abundance of human-associated viruses and bacteria along with lower abundance of sewer-associated bacteria suggests a mechanism where airplane wastewater has a higher ratio of human- to sewer-derived input, boosting human viruses across the board.
