🚨Important Health Update from Dr. Virginia Ellsworth & East Dallas Veterinary Clinic 🚨
Dear EDVC Clients and Community,
We want to provide you with an important update regarding the growing concern surrounding the New World Screwworm (NWS).
At this time, New World Screwworm has NOT been detected in the United States. However, cases have been confirmed in two Mexican states bordering Texas, with the closest confirmed case currently located approximately 62 miles south of McAllen, Texas.
The Texas Veterinary Medical Association (TVMA) recently testified before the Texas Senate Committee on Water, Agriculture, and Rural Affairs emphasizing that ALL veterinarians in Texas — including companion animal veterinarians — will play a critical role in early detection, prevention, and public education.
📊 Current Confirmed Cases in Mexico Include:
• 913 cattle
• 455 dogs
• 136 swine
• 88 horses
• 1 cat
• 1 endangered howler monkey
The United States has already implemented several proactive measures, including:
✔️ Closing southern livestock ports
✔️ Opening a sterile fly dispersal facility in South Texas
✔️ Expanding sterile fly production capabilities
✔️ Authorizing emergency use medications for prevention and treatment support
✔️ Investing over $100 million into NWS response initiatives
🐾 What This Means for Pet Owners
Pet owners should remain vigilant and monitor pets closely for:
• Unusual wounds or skin lesions
• Excessive licking or irritation
• Drainage or foul odors from wounds
• Signs of infection or discomfort
If you notice anything concerning, contact your veterinarian immediately.
