Avian flu was detected in wastewater before the first reported outbreak among Texas dairy cattle in 2024.
LOS ANGELES — Researchers found a biomarker for avian flu in Texas wastewater treatment plants more than a month before the first confirmed cases of H5N1 among Texas dairy cattle in 2024, according to new data presented at the
Researchers were looking to explain unseasonal spikes in influenza A virus seen in Texas wastewater treatment plants in early 2024. Zulli and colleagues turned to wastewater monitoring, which had been used historically to track viruses for cholera, typhoid, and polio but recently was used to track severe acute respiratory syndrome coronavirus 2. Zulli noted wastewater-based epidemiology is useful with tracking an array of other pathogens, such as influenza and respiratory syncytial virus.
At a wastewater plant in Amarillo, Texas, he said, retrospective sampling by the Stanford team found that H5N1 had been detected on February 24, 2024, 2 weeks before cattle illnesses were reported in Texas. “The first cattle illness was reported on March 7, and at that point they didn’t know what it was,” Zulli said. The first confirmed detection ofwas on March 25. A month can give public health officials a good amount of time to develop a response, he said.
