The testing would be suitable for settings ranging from hunting, trapping and animal production to veterinary clinics and at home.<\/p>\n\n\n\n<p>The project spans both hardware and software components. The hardware is the test for field use. The software is for uploading the results to a dashboard to monitor spread of the virus in different animals and locations.<\/p>\n\n\n\n<p>APHIS and its partners completed&nbsp;<a href=\"https:\/\/www.aphis.usda.gov\/aphis\/ourfocus\/onehealth\/one-health-studies\" rel=\"noreferrer noopener\" target=\"_blank\">studies<\/a>&nbsp;that showed the virus spread to various animal species, wildlife included. For&nbsp;<a href=\"https:\/\/www.aphis.usda.gov\/aphis\/ourfocus\/onehealth\/one-health-white-tailed-deer\" rel=\"noreferrer noopener\" target=\"_blank\">white-tailed deer<\/a>, their research conducted in 2021 revealed that approximately 40% of the samples contained SARS-CoV-2 antibodies, suggesting that the virus was circulating in the states that were evaluated.<\/p>\n\n\n\n<p>\u201cThere is a potential for COVID-19 to be resident in animals and then spill back to humans,\u201d Verma said. \u201cThat\u2019s the concern, and that can happen. That\u2019s why we are developing better tools for surveillance in wildlife, companion animals and farm animals.\u201d<\/p>\n\n\n\n<p>The problem disproportionally affects tribal nations, whose members maintain close contact with wildlife both for subsistence and cultural reasons. An April 2022 Congressional<\/p>\n\n\n\n<p>hearing on \u201cPreventing Pandemics through U.S. Wildlife-borne Disease Surveillance\u201d highlighted the need to involve tribal nations in the process. Likewise, the Department of Natural Resources and the U.S. Geological Survey could use better surveillance tools to help guide outdoors enthusiasts nationally.<\/p>\n\n\n\n<p>\u201cWe thought about what could be the most universal and could still be used in the field across different users,\u201d Verma said. The team settled on oral-nasal swabs because they can sample what often is a shared cavity in animals.<\/p>\n\n\n\n<p>The team will focus on the SARS-CoV-2 virus, but the tools could apply to other viruses and emerging diseases as needed. The project will build off Verma\u2019s ongoing work in animal and human health. Verma has&nbsp;already developed innovative paper-based, rapid-result tests for&nbsp;<a href=\"https:\/\/link.springer.com\/article\/10.1186\/s13567-021-00997-9\" rel=\"noreferrer noopener\" target=\"_blank\">bovine respiratory disease<\/a>&nbsp;and&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2590137021000121\" rel=\"noreferrer noopener\" target=\"_blank\">COVID-19<\/a>&nbsp;and is in the process of commercializing these through his startup&nbsp;<a href=\"https:\/\/krishidiagnostics.com\/\" rel=\"noreferrer noopener\" target=\"_blank\">Krishi Inc<\/a>.<\/p>\n\n\n\n<p>\u201cWe\u2019re hoping that the tools we develop will be amendable to low-resource use and can be deployed widely,\u201d Verma said. The availability of results could be reduced from one day to an hour at a cost of about $10 per test.<\/p>\n\n\n\n<p>A key goal will be to improve the test\u2019s sensitivity. Because it was designed to be simple and user-friendly, the test Verma developed for humans was less sensitive than laboratory-based quantitative polymerase chain reaction (qPCR) tests. Both animal size and the rate of virus replication determine the needed sensitivity level, he noted. Many animals not yet susceptible may become susceptible if the virus mutates.<\/p>\n\n\n\n<p>\u201cA lot of this is not known. We are comparing ourselves to what we can do in the lab,\u201d he said. \u201cIf you take the same sample, do all the purification and extraction in the lab, then do this qPCR test, what levels can you get?\u201d<\/p>\n\n\n\n<p>Ideally, the team will develop a test sensitive to the virus at low levels, even before an animal begins showing clinical signs.<\/p>\n\n\n\n<p>Project funding stems from the&nbsp;<a href=\"https:\/\/www.usda.gov\/arp\" rel=\"noreferrer noopener\" target=\"_blank\">American Rescue Plan Act<\/a>&nbsp;for work focusing on the&nbsp;<a href=\"https:\/\/www.aphis.usda.gov\/aphis\/ourfocus\/onehealth\/onehealth\" rel=\"noreferrer noopener\" target=\"_blank\">One Health Concept<\/a>, which recognizes the link between the health of people, animals and the environment.
