The Texas Department of State Health Services has confirmed the first human case of avian influenza A(H5N1) virus in Texas, with the individual having direct exposure to dairy cattle presumed to be infected with the virus. The patient, whose only symptom was inflammation of their eyes, underwent testing late last week. The tests were conducted by the Centers for Disease Control and Prevention over the weekend.
This case marks the second human instance of H5N1 flu in the United States and the first associated with exposure to cattle. In response, the Texas Department of State Health Services (DSHS), in collaboration with various health agencies, is actively investigating both human and animal cases to understand the spread of the virus and safeguard livestock and individuals in contact with them.
Authorities have assured that the general public's risk remains low despite this development. The department emphasized that avian influenza A(H5N1) typically infects wild birds and can spread to domestic birds and other animals, with limited transmission to humans. Initial testing indicates no changes in the virus that would increase its human-to-human transmissibility.
While the infections in dairy cattle are being monitored, they do not pose a threat to the commercial milk supply, according to DSHS. State and Federal agencies have measures in place to ensure the safety of milk products, including the destruction or diversion of milk from any affected cows.
In response to these events, DSHS is offering guidance to impacted dairies on minimizing worker exposure and monitoring for flu-like symptoms among personnel in contact with affected cattle. Additionally, health care providers near affected areas have been urged to remain vigilant for potential human cases, with testing and treatment recommendations being provided.
The department highlighted the range of symptoms associated with H5N1 flu infections, from mild symptoms like eye infections and respiratory issues to severe conditions such as pneumonia and fatality.
