Patients will be screened and enrolled by study coordinators at each site, who will collect and submit biospecimens as well as patient characteristics and clinical outcomes. Metagenomic NGS will be performed on these biospecimens in an attempt to identify microbial pathogens and markers of host response to infection, including immune activation, inflammation, and cell damage.
