Wastewater Epidemiology
Wastewater-based epidemiology (WBE) aims at measuring pathogens in wastewater at population scale.
This approach has proven to enable advanced warning ahead of clinical testing or hospitalizations, for public agencies and communities to better prepare for and prevent the spread of infectious diseases.
Hyperplex PCR™ is currently being used to monitor the spread of COVID variants in Sweden together with the Swedish Environmental Epidemiology Centre (SEEC) and is now available to be deployed world-wide.

Why Hyperplex PCR for pandemic preparedness?
With multiplexing unleashed, Hyperplex PCR enables shorter time to action by enabling instant set-up and in real-time updating of panels with unparallaled specificity and sensitivity for routine monitoring and better pandemic preparedness systems.

SARS-CoV-2 variants surveillance data
Together with the Swedish Environmental Epidemiology Center (SEEC), SARS-CoV-2 variants in Sweden are being monitored using Hyperplex PCR.
​
Up to 20 sites have been monitored with a 18-plex panel enabling monitoring unparallalled by other methods such as qPCR, dPCR and NGS.
​
The panel as been adapted to keep it up-to-date with relevant variants of concern by removing exting variants and swiftly add new mutations within 2 weeks from order.
​
Read about some of the conclusions reached in our application note.
Figure 1. Heatmap summary of SARS-CoV-2 VOC surveillance data generated with Hyperplex PCR over one year with an adaptable 18-plex panel for up to 20 sites in Sweden. Heatmap colors represent as following; blue (no signal detected), from green (low concentration) to pink (high concentration) of marker detected.
NGS-grade quantification of mutation frequency
Figure 2. A, B: Mutation frequency measured in wastewater with NGS (filled symbols) and hpPCR (open symbols). C: Linearity of mutation frequency measurements using hpPCR in a 10-plex target system (spiked targets). D: hpPCR vs NGS mutation frequency in WW samples.
4+ weeks earlier detection of emerging variants
Figure 3. Weekly measurement of S:F486P, characteristic of XBB 1.5 using hpPCR and NGS (Ion torrent). 8 wastewater collection sites were measured at each time point. Both measurements were performed on the same extracted nucleic acid sample.
Negligible inhibitor effect
Figure 4. Intensity of N3 gene marker obtained after hpPCR on DNAse/RNAse-free water (pink) and 29 different wastewater samples (green). The wastewater samples were processed with a standard off-the-shelf total nucleic acid extraction kit.
AMR analysis of low and high abundance targets
In this project, Hyperplex PCR was used for absolute quantification of 5 AMR markers in wastewater samples, showcasing the read-out of both high and low abundance markers from the same sample.
