Galveston County, TX — The Galveston County Health District (GCHD) is reporting
confirmed cases of Avian influenza in local birds. Animal testing has identified Influenza
Type A that is positive for the H5 strain which is presumptively positive for Highly
Pathogenic Avian Influenza (HPAI).
A total of 27 birds have been reported deceased. Of the 27, 6 birds have been sent to the
University of Texas Medical Branch (UTMB) for further diagnostic testing and confirmation.
Ten individuals were identified as having direct contact with the infected birds. All
individuals have been evaluated. Those experiencing any symptoms were tested, and all
results returned negative for influenza. Out of an abundance of caution, all eight individuals
are currently taking Tamiflu (oseltamivir) as post-exposure prophylaxis (PEP).
At this time, in Galveston County, there is no evidence of human-to-human transmission,
and the risk to the general public remains low.
Cat Owners: Important Advisory
Because Avian Influenza can infect some mammals that come into contact with sick or
dead birds, GCHD is asking cat owners to be cautious. Outdoor cats that hunt or scavenge
birds may be at higher risk of exposure.
Cat owners should watch for the following symptoms in their pets:
• Sudden or unusual lethargy
• Loss of appetite
• Fever
• Difficulty breathing or rapid breathing
• Eye or nasal discharge
• Neurologic symptoms such as stumbling, tremors, or disorientation
• Sudden death
Any cat showing these symptoms, especially if it may have been exposed to wild birds,
should be evaluated by a veterinarian immediately. Indoor cats are considered to be at low
risk.
GCHD continues to work closely with UTMB, the Texas Department of State Health
Services (DSHS), Texas Parks and Wildlife, and local partners to monitor the situation and
implement appropriate public health measures.
The public is urged to avoid contact with sick or dead birds and to report unusual bird
deaths to the Galveston County Animal Resource Center at 409-948-2485.
