Multiplexed digital PCR techniques to monitor public health threats, including SARS-CoV-2 and hMPXV

Several academic, industry and public health laboratories successfully implemented wastewater-based epidemiology (WBE) to track community-wide infection trends during the COVID-19 pandemic. Digital PCR (dPCR) technologies offer ultra-sensitive detection and resistance to inhibitors commonly present in concentrated wastewater extracts. As such, the Centers for Disease Control and Prevention (CDC) strictly endorses dPCR datasets for WBE. The current status of the pandemic seen through the WBE lens, unfortunately, reveals a spike across the United States. Mutational signature dPCR approaches indicate this spike is likely due to the Omicron BA.5 lineage’s rapid emergence and spread.

Further, shedding patterns of human monkeypox virus (hMPXV), a burgeoning, worldwide, and quickly spreading pathogen, reveal a putative WBE candidate. Attendees of this webinar will learn about dPCR approaches to monitor community-wide hMPXV viral loads with a limit of detection of <5000 copies/L starting wastewater. The GT Molecular team offers end-to-end testing service and PCR assay solutions that include Poxvirus matrix recovery control and fecal indicator normalization targets. As such, the scientific community will be poised to provide data that help steer public health decisions surrounding this recent and growing public health threat.
