We have had several questions about New World screwworm, so we wanted to share a calm, practical update for pet owners.
At this time, we have not seen confirmed cases in Burnet or Llano County.
There is no need to panic, but prevention and early wound care are VERY important.
The most important things pet owners can do right now are simple:
1. Keep pets on monthly flea/tick prevention
2. Call your veterinarian right away if a wound gets worse, smells, drains, or has maggots
3. Check wounds, ears, feet, surgery sites, hot spots, and irritated skin regularly
4. Keep any wound clean, protected, and treated promptly
For most owned pets receiving regular care (INCLUDING FULL SCALE PREVENTITIVE), the risk is low. Staying aware, keeping pets protected, and catching wounds early are the best ways to help keep animals safe.
HCHS will continue monitoring updates and taking precautions with animals coming into our care.
