As many unanswered questions remain about the recent outbreaks of High-Path Avian Flu (HPAI) H5N1 in dairy cattle, researchers are looking at many possible options on how the virus is being transmitted — including wastewater testing.
According to the pre-published results of a wastewater study conducted in Texas by researchers at Baylor University, wastewater from 10 cities across the state was tested. Of those samples, nine tested positive for HPAI.
The specific city names were not included in the study (researchers said these cities’ identities are masked at the request of local public health officials and water utilities), but the geographic spread encompasses areas across the state. In those places, 23 total samples were collected and 19 tested positive. A least one positive sample was collected from nine of the 10 cities where samples were collected.
Here is the researcher’s conclusion:
