The National Veterinary Services Laboratories (NVSL) has officially confirmed the presence of Highly Pathogenic Avian Influenza (HPAI) in various locations across Texas. According to disease experts, HPAI is currently spreading among wild birds in the state, particularly among waterbirds and waterfowl that are currently residing in their wintering grounds.
Wharton, Galveston, and Harris counties have reported the most recent detections.
HPAI poses a significant threat as it is a highly contagious virus that spreads easily among both wild and domestic birds. The transmission of the virus can occur directly between animals or indirectly through environmental contamination. What’s alarming is that HPAI has been found in wildlife across all contiguous states.
Wildlife rehabilitators should exercise caution when accepting wild animals with clinical signs that align with HPAI (highly pathogenic avian influenza), as it is easily transmissible. The Texas Parks and Wildlife Department (TPWD) advises quarantining such animals to minimize the risk of HPAI spreading to other animals within the facility.
To help prevent the spread of HPAI, it is important for the public to minimize unnecessary contact with wild birds. It is recommended to clean bird feeders and water sources every two weeks using a solution of one part bleach and nine parts water. Additionally, birdbaths should have their water changed every few days, and any wet feed or seed should be promptly removed from feed and water sources.
In addition, it is important for game bird hunters to take certain precautions, including:
-
- Disposing carcasses properly
- Wearing gloves when processing
- Avoiding consumption or processing of any sick bird
- Cleaning and disinfecting tools between carcasses
- Cooking meat to proper temperatures
The risk of avian influenza transmission from infected birds to humans is currently low. However, if contact with wild animals cannot be avoided, it is important for the public to take basic protective measures. For more information on avian influenza in humans, both the public and healthcare professionals can refer to the Texas Department of State Health Services. If you have had contact with an HPAI-positive animal and experience any signs of illness, it is crucial to contact your healthcare provider immediately and inform them about the exposure.
If you come across a wild animal showing symptoms that are consistent with HPAI, make sure to get in touch with your local TPWD wildlife biologist.
