Abstract We measured stability of infectious influenza A(H5N1) virus in irradiated raw milk and wastewater and on surfaces . We found a relatively slow decay in milk , indicating that contaminated milk and fomites pose transmission risks . Although the risk is low, our results call for caution in milk handling and disposal from infected cattle.

Summary -- What is already known about this topic? -  Highly pathogenic avian influenza A(H5N1) outbreaks have emerged in U.S. cattle and poultry . Wastewater surveillance detects influenza A(H5) subtype but does not currently distinguish between human and animal sources. -- What is added by this report? -  During September 15, 2021–July 11, 2024 , retrospective analysis of wastewater surveillance data revealed 21 avian influenza A(H5) subtype detections across 12 Oregon communities . No association was found between detections in a community’s wastewater and history of a poultry outbreak 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 . -- What are the implications for public health practice? -  Wastewater surveillance was an early indicator of avian influenza emergence in Oregon. Nonhuman and noncattle animal inputs , including wild bir...

Abstract The COVID-19 pandemic has increased the interest in the use of wastewater-based surveillance (WBS) strategy for infectious disease monitoring, especially when clinical cases are underreported. The excretion of monkey virus (MPXV) in the feces of both symptomatic and preclinical individuals has further driven the interest in WBS applicability to MPXV monitoring in wastewater to support its mitigation efforts. We performed a systematic review with meta-analysis, using six databases to assess MPXV detection in wastewater. We performed a random-effects model meta-analysis to calculate the pooled prevalence at a 95% confidence interval (95% CI). Also, we carried out a subgroup analysis according to the country regions and a sensitivity analysis excluding studies classified as having a high risk of bias. The overall MPXV positivity rate in wastewater was estimated at 22% (95% CI: 14−30%; I2 = 94.8%), with more detection rate in North America (26%, 95% CI: 8–43%) compared to Europe a...

{Excerpt} HONOLULU — The Hawai‘i Department of Health (DOH) State Laboratories Division has detected H5 avian influenza (bird flu) at very low levels in wastewater samples collected at the Līhuʻe Wastewater Treatment Plant on Kauaʻi. The first detection was from a sample collected on Dec. 11, 2024 , that was so low that it was not considered a positive result.  Samples collected on Dec. 18, 2024 and Jan. 8, 2025 had similar detections.  While none is considered a positive result , the consistent very low-level detections indicate a high likelihood that H5 bird flu virus is on Kauaʻi.  No H5 virus infections of birds, dairy cows, or humans have been detected on Kauaʻi to date.  Detection of infected birds in the state has so far been limited to Oʻahu. The H5 bird flu viruses include the H5N1 subtype of bird flu virus that has spread globally in birds since its initial discovery in 1996 and recently has been detected in several mammal species including dairy cows. Wast...

Abstract In 2024, the highly pathogenic avian influenza A H5N1 caused outbreaks in wild birds, poultry, cows, and other mammals in the United States with 61 human cases also reported by the CDC. Detection of influenza A H5 RNA in wastewater has been previously reported in sewersheds in Texas and North Carolina with nearby impacted dairy herds following the emergence of H5N1 in dairy cows. Here, we conduct retrospective testing of total influenza A and H5 hemagglutinin genes in wastewater as well presenting and applying new assays for detection of H1 and H3 genes across a respiratory virus season in an urban California sewershed from September 2023-May 2024. Total influenza A, H1, and H3 were regularly detected, while H5 was first detected in March . We developed a model that uses Monte Carlo simulations and previously published parameters to estimate numbers of infected people, poultry, wild birds, or liters of H5-contaminated milk required to result in measured H5 concentrations in wa...
