get our waste as far away from ourselves as possible.<sup>1</sup> That effort has continued to the modern-day, where the sewers under our feet carry <a href="https://on.nyc.gov/3DblmkV" target="_blank" rel="noopener">billions of gallons of waste</a> (every day!) away from our most populated areas.<sup>2</sup></p> <p>It is the pinnacle of ‘out of sight, out of mind.’</p> <p>But in flushing and forgetting our waste, we are also flushing a wealth of information about our biology and the infectious diseases that threaten our health. What if, we could use our waste to spot the outbreak of disease before a community even starts to show symptoms? It’s a powerful thought and one that could change public health. And it’s not new. The concept of <a href="https://www.thermofisher.com/us/en/home/life-science/sequencing/fragment-analysis/fragment-analysis-applications/pathogen-detection-and-analysis.html?icid=bid_sap_aut_r01_co_cp1434_pjt8107_EXT1281_0so_blg_op_awa_kt_s00_typewriter1" target="_blank" rel="noopener">pathogen detection</a> through <strong>wastewater testing</strong> is centuries old.</p> <h3>Monitoring the Complexities of the Human Microbiome</h3> <p>What makes wastewater pathogen detection so valuable is the incredible quantity of microbes that live within our digestive tracts. These microbes, comprising the <a href="https://bit.ly/3lgOS2R" target="_blank" rel="noopener">gut microbiome</a>, play an incredible (though poorly understood) role in overall human health, for everything from digestion to <a href="https://bit.ly/3BdaliD" target="_blank" rel="noopener">cardiac health</a> to the immune system.<sup>3,4</sup> Viruses, bacteria, fungi, and other microbes form a complex system within the gut, competing with invading pathogens for attachment sites and nutrients, aiding in carbohydrate digestion, producing vitamins, and more. Many biological functions that need to be executed for us to survive are carried out by the <a href="https://www.thermofisher.com/blog/behindthebench/the-human-microbiome-new-frontiers-in-medical-research/?icid=bid_sap_aut_r01_co_cp1434_pjt8107_EXT1281_0so_blg_op_awa_kt_s00_typewriter2" target="_blank" rel="noopener">human microbiome</a>. We can find evidence of the organisms contained within it in the fecal matter we eliminate and draw conclusions about the health of the subject or community from where it came. While the concept of getting this waste far away from where we live may be as old as human settlement, the idea to utilize that same waste to monitor health and disease on both the individual and community level is a much more recent development, dating back to the 19th century.</p> <p><iframe title="Mapping the Journey of Dr. Christopher Mason through the world of Microbiome" width="760" height="428" src="https://www.youtube.com/embed/hbAPvkstcXU?feature=oembed" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></p> <h3>Wastewater Surveillance Through the Centuries: A Timeline</h3> <p>The first waterborne disease to be scientifically documented was the <a href="https://academic.oup.com/ije/article/12/4/393/685217?login=true" target="_blank" rel="noopener">Broad Street </a>cholera outbreak of 1854 in London.<sup>5</sup> Impressively, <a href="https://pubmed.ncbi.nlm.nih.gov/15559385/" target="_blank" rel="noopener">Dr. John Snow</a> (the father of epidemiology, not of Winterfell) was able to convince local officials of the disease’s source and vehicle of transmission decades before germ theory had been proven.<sup>6</sup> Snow managed this feat by comparing the water sources of disease-stricken and untouched households and tracked the outbreak to a single pump on Broad Street. Ever since, epidemiologists have looked to water for answers about how diseases are spread, and how they might be tracked without relying on large-scale individualized testing.</p> <p>In the 1940s, epidemiologists utilized wastewater to track and contain disease outbreaks in the United States, <a href="https://pubmed.ncbi.nlm.nih.gov/8561468/" target="_blank" rel="noopener">particularly polio</a>.<sup>7</sup> The cell culture methods used were crude by today’s standards, but effective nonetheless, and wastewater surveillance remains a critical tool for eradicating polio across the globe.<sup>8</sup> Still, many pathogens are either difficult or impossible to culture, and more efficient and cost-effective methods have been developed, like hybridization with radioactive cDNA probes to <a href="https://pubmed.ncbi.nlm.nih.gov/2447830/" target="_blank" rel="noopener">monitor Hepatitis A</a> in the 1980s.<sup>9</sup> It wasn’t until the 1990s, however, that the gold standard of <a href="https://www.sciencedirect.com/science/article/abs/pii/S0043135499000718" target="_blank" rel="noopener">wastewater pathogen detection</a> techniques was brought to the front lines with PCR.<sup>10,11</sup></p> <p>Because PCR can be quick and efficient,<a href="https://pubmed.ncbi.nlm.nih.gov/25172863/" target="_blank" rel="noopener"> detection of pathogens in wastewater</a> can be done even before those infected start to show symptoms.12 Recently, innovative and highthroughput PCR-based workflows have been used for ongoing monitoring of the COVID-19 pandemic. As nasal swab testing was limited and often delayed in the early stages of the global spread of SARS-CoV-2, <a href="https://www.thermofisher.com/us/en/home/life-science/dna-rna-purification-analysis/automated-purification-extraction/automated-magmax-kits-nucleic-acid-extraction/magmax-microbiome-extraction-kits/wastewater-surveillance.html?icid=bid_sap_aut_r01_co_cp1434_pjt8107_EXT1281_0so_blg_op_awa_kt_s00_typewriter7" target="_blank" rel="noopener">wastewater testing </a>was suggested as a way to bypass some of the bottlenecks in our testing infrastructure and identify areas where outbreaks were just starting, long before case numbers, hospitalizations, and deaths took off. Some universities used this strategy to identify which dormitories required individual testing. <a href="https://doi.org/10.1101/2021.06.18.21259162" target="_blank" rel="noopener">A recent study</a> from a university may be good resource to add to this list (They used the KingFisher Flex platform). Here is the<a href="https://scitechdaily.com/85-of-campus-covid-19-cases-detected-early-by-uc-san-diegos-wastewater-screening/" target="_blank" rel="noopener"> link</a> to the preprint. Rapid, large-scale wastewater surveillance and automated reporting system enabled early detection of nearly 85% of COVID-19 cases on a University campus.</p> <h3><strong>Modernizing the Approach to Wastewater Surveillance</strong></h3> <p>While wastewater detection shows immense promise, both for the current pandemic and beyond, a detection method is only as effective as the quality of extracted proteins or nucleic acids (DNA or RNA) allows it to be. Our <a href="https://www.thermofisher.com/us/en/home/life-science/dna-rna-purification-analysis/automated-purification-extraction/automated-magmax-kits-nucleic-acid-extraction/magmax-microbiome-extraction-kits.html?icid=bid_sap_aut_r01_co_cp1434_pjt8107_EXT1281_0so_blg_op_awa_kt_s00_typewriter3" target="_blank" rel="noopener">MagMAX Microbiome Ultra Nucleic Acid Extraction Kits</a> can help with the challenging sample types required for microbiome detection and <a href="https://www.thermofisher.com/us/en/home/life-science/dna-rna-purification-analysis/automated-purification-extraction/automated-magmax-kits-nucleic-acid-extraction/magmax-microbiome-extraction-kits/wastewaterresources"><strong>wastewater testing</strong></a>. And there’s a bonus: The kit is automation-ready, allowing higher throughput with Thermo Fisher’s <a href="https://bit.ly/3uFfMnS" target="_blank" rel="noopener">KingFisher Flex sample purification system</a>.
