There are discussions about including influenza, RSV, and Mpox, previously often known as monkeypox, to what’s examined for in wastewater, he mentioned, whereas different potentialities embody antimicrobial resistance genes and opiates.
However LaCross mentioned the state has dominated out monitoring wastewater for polio “for now,” regardless of a pattern collected in February 2022 in northern Utah for an out-of-state researcher testing constructive for poliovirus.
Whereas the info collected from wastewater doesn't determine particular person circumstances, he mentioned it helps public well being officers goal sources corresponding to details about mandatory precautions to areas the place that’s most wanted, he mentioned.
