From WIRED article: When Nebraska was notified that it would be receiving some of the passengers, Iwen contacted the US Centers for Disease Control and Prevention to see if it had tests on hand. He learned that the CDC has the ability to run a serological test, which looks for the presence of hantavirus antibodies. But people don’t develop antibodies until they are actively sick and their body has had time to mount an immune response. Andrew Nixon, a spokesperson for the US Department of Health and Human Services, told WIRED that the CDC has a PCR test for the Andes virus but that it’s a research test that cannot be used for patient management. Research tests are used in scientific experiments, while diagnostic tests that are meant to confirm or rule out a disease in patients need to be rigorously tested, or validated, to make sure they are capable of producing consistent results. Nixon said the agency is working on validating its PCR test.

APHIS will consider project proposals that clearly and directly support one or more of the topics described below. Regardless of the priority topic, applicants are encouraged to submit proposals that: Topic 1. Develop novel vaccines to protect poultry from highly pathogenic avian influenza (HPAI). Topic 2. Develop novel therapeutics to address HPAI in poultry. Topic 3. Conduct research to further understand avian influenza in poultry and to improve response strategies.

"The reason for sharing what I'm going to say is that we're workers on a farm and we've been affected by a flu/virus, a cough that none of us has been able to avoid," the statement said in part. "We spent one or two days in bed suffering from a fever and sore throat...We hope that through this communication, there can be protective equipment for the other ranches, since we've already gotten PPE at the ranch where we are working...If the protective equipment had arrived faster, we might not all have gotten sick."

Abstract. Wastewater surveillance is an important tool in the surveillance of emerging pathogens and has been leveraged during the highly pathogenic avian influenza (HPAI) A(H5N1) virus outbreak in cattle and poultry in the United States. Interpretation of avian influenza A(H5) subtype detections in wastewater requires an understanding of human and animal contributors to the sewershed because current testing does not distinguish between human and animal sources. Potential animal contributors include wild birds, farms with poultry or dairy cattle outbreaks, and dairy processing facilities. Retrospective analysis of 551 influenza A virus–positive wastewater surveillance samples from 20 sites in Oregon during September 15, 2021–July 11, 2024, revealed 21 avian influenza A(H5) subtype detections across 12 communities. Avian influenza A(H5) subtype detections in wastewater began approximately 6 weeks before Oregon’s first HPAI outbreak in domestic poultry, 7 weeks before Oregon’s first avian influenza A(H5) detection in wild birds, and 2 years before the first HPAI A(H5N1) outbreak in dairy cattle in the United States (Oregon has not detected HPAI A(H5N1) in dairy cattle or milk). No association was found between detection of avian influenza A(H5) in a community’s wastewater and history of an HPAI A(H5) outbreak among poultry in the county or presence of dairy processing facilities or dairy farms within the sewershed. Avian influenza A(H5) was detected most frequently in two communities with important wild bird habitats. Animal inputs, including from wild birds, should be considered when interpreting avian influenza A(H5) subtype detections in wastewater.
