TRAVIS COUNTY, Texas - While Travis County has seen a decline in the numbers of fentanyl poisoning deaths, it's seen an increase in unknown opioids posing a risk to the community.

By the numbers: A new city memo reveals opioid-related deaths in Travis County are down 35%.

Officials credit expanded naloxone distribution and community harm reduction investments for the decline, but Austin-Travis County EMS data points to another emerging threat.
