Wastewater testing offers a real-time, noninvasive way to estimate how many people may be affected by a health condition in a community, particularly when traditional health systems cannot. But this powerful tool only works where modern sewer systems exist\u2014even though the next pandemic could begin anywhere.<\/p>\n<p>To help fill this gap, researchers from the Gerald J. and Dorothy R. Friedman School of Nutrition <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> and Policy at Tufts University, Cummings School of Veterinary Medicine at Tufts University, and Tufts University School of Medicine teamed up with international collaborators to see whether wastewater testing could work in places without modern plumbing.<\/p>\n<p>In a study published in <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/journals.plos.org\/water\/article?id=10.1371\/journal.pwat.0000290\" target=\"_blank\"><i>PLOS Water<\/i><\/a>, the team showed that they could detect signs of disease in wastewater flowing through open channels in two urban neighborhoods and a poultry market in West Africa.<\/p>\n<p>Daniele Lantagne, a research professor at the Feinstein International Center at the Friedman School and the study&#8217;s senior author, discussed why making wastewater surveillance more accessible matters.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_wastewater_surveillance_and_how_does_it_work\"><\/span>What is wastewater surveillance and how does it work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most Americans first heard about wastewater surveillance during the COVID-19 pandemic, when it helped public health officials track outbreaks. But the idea has been around much longer. For example, the Global Polio Eradication Initiative has used it to confirm that countries are free of polio, and even law enforcement has tapped it to trace illegal drug production.<\/p>\n<p>Today, across the United States, sewage from many cities and towns will flow into a single wastewater treatment plant. Giant pipes carry this wastewater in, and special devices can take small samples from these pipes every few minutes.<\/p>\n<p>Health officials may have only tested for the virus that causes COVID-19 at first. But now many regions also test for viruses that cause flu and RSV and other pathogens.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2025\/can-wastewater-surveil-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2025\/can-wastewater-surveil-1.jpg\" data-sub-html=\"Cote d'Ivoire laboratory staff set up a passive sample of water runoff from cleaning poultry at an urban market.

That makes it easy to sample and test the water. But around the world, more than 3.5 billion people don&#8217;t have access to this kind of safely managed sanitation. Waste often ends up in open drains or pits, so the usual wastewater testing methods just don&#8217;t work.<\/p>\n<p>Our team wanted to find out if we could make this tool useful in places without modern plumbing and sewer systems. That meant figuring out where to collect samples, what diseases to test for, and how to train local teams to do the work themselves.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"So_what_did_your_team_find\"><\/span>So, what did your team find?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>We focused on two kinds of high-risk places in C\u00f4te d&#8217;Ivoire in West Africa: open wastewater channels from crowded urban neighborhoods and water used to clean poultry in local markets. We wanted to see if we could detect two major threats: SARS-CoV-2, the virus behind COVID-19, and influenza A, a virus that causes bird flu. Over 12 weeks, we collected samples and had them tested in local labs.<\/p>\n<p>Nearly half of the human wastewater samples showed signs of COVID-19, and we found flu virus in some of the poultry wastewater.<\/p>\n<p>What&#8217;s exciting is that this is one of the first times wastewater surveillance has been used in such low-resource settings. We also trained local scientists and proved that this kind of testing can work\u2014even without expensive infrastructure.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2025\/can-wastewater-surveil-2.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2025\/can-wastewater-surveil-2.jpg\" data-sub-html=\"Cote d'Ivoire laboratory staff undergo biosafety training on sampling collection procedures at the waste discharge area of a rural hospital.

If a dangerous virus like Ebola emerges in C\u00f4te d&#8217;Ivoire, it&#8217;s just one plane ride away from the U.S. As people move into previously remote areas, we&#8217;re seeing more chances for new diseases to jump from animals to humans.<\/p>\n<p>Catching those threats early\u2014right where they begin\u2014is the best way to prevent them from spreading. That&#8217;s why the U.S. has long invested in public health systems around the world. Wastewater surveillance is another smart tool in that toolbox.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_else_should_we_tap_the_power_of_wastewater_testing\"><\/span>How else should we tap the power of wastewater testing?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>We need to keep asking when wastewater testing will have the most impact. It&#8217;s especially useful in places where diseases spread silently\u2014when people don&#8217;t show symptoms or can&#8217;t access testing.<\/p>\n<p>For example, Lassa fever, a disease carried by rats in West Africa, is likely far more widespread than we realize. It often looks like malaria, so it&#8217;s frequently misdiagnosed. And while many people have mild symptoms, others get very sick with severe hemorrhagic illness\u2014similar to Ebola\u2014and die. Wastewater could help track its true spread.<\/p>\n<p>In fact, during our study, we were about to test wastewater from a rural hospital in C\u00f4te d&#8217;Ivoire where all the waste flows untreated into a nearby forest. We expected to detect the Lassa virus\u2014which the hospital can&#8217;t test for\u2014but the project was canceled due to federal budget cuts affecting our funder, the U.S. Agency for International Development (USAID).<\/p>\n<p>That kind of setback shows why we need more support to prove that viruses like Lassa can be detected in wastewater using low-cost, locally available tools.<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n                                                    Ell\u00e9l\u00e9 Aim\u00e9 Marius Yapi et al, Expanding access to wastewater surveillance beyond sewered networks: Effectiveness of active and passive sampling of waste effluent streams in C\u00f4te d&#8217;Ivoire, <i>PLOS Water<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1371\/journal.pwat.0000290\" target=\"_blank\">DOI: 10.1371\/journal.pwat.0000290<\/a><\/p>\n<\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n\t\t\t\t\t\t\t\t\t\t\t\tProvided by<br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tTufts University<br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/now.tufts.edu\/\" target=\"_blank\" rel=\"nofollow\"><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<use href=\"https:\/\/medx.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Q&amp;A: Can wastewater surveillance work without sewers?
