Swab Sampling Recruitment

The Nucleic Acid Observatory (NAO) aims to detect new pandemics more quickly than currently possible. As one of our efforts, we are piloting swab-based surveillance in the Boston metropolitan area. Based on prior research, nasal swabs show high viral loads and could be a promising sample type for detecting rapidly spreading respiratory pathogens.

Here we present real-time data of our surveillance effort, displaying:

All published sequencing data has been scrubbed of human genetic material to ensure privacy.
