The threat of Avian Flu, commonly known as bird flu, intensifies as the U.S. confirms its second human case. Texas authorities have reported the first case in the state, with a person contracting the flu after close contact with infected cows. This development follows the USDA’s confirmation of bird flu cases in mammals in Washington, Kentucky, and Montana just a week prior.
On April 1, the Texas Department of State Health Services (TDSHS) announced the diagnosis of a patient with avian influenza. The individual had been in contact with dairy cows suspected of carrying the virus. The primary symptom exhibited by the patient was “pink eye,” also known as conjunctivitis. However, TDSHS emphasized that the risk to the general public remains low despite this new case involving direct exposure to suspected infected cattle.
Second Avian Flu Case in the US
Texas officials declared this as the first reported case of the highly pathogenic strain of avian influenza in humans in the state and the second in the entire country. Previously, an individual in Colorado was reported to have been infected with H5N1 after direct contact with infected poultry.

Concerns Over Avian Flu Cases in Mammals
The Centers for Disease Control and Prevention (CDC), the United States Department of Agriculture (USDA), and the United States Food and Drug Administration (FDA) jointly started on March 29th to address concerns. They assured the public about the safety of dairy products in the United States, stating that pasteurization ensures their safety before sale. Before this, US officials had cautioned about the potential increase in cases of highly pathogenic avian influenza (H5N1) among marine mammals.
Can Humans Contract Avian Flu?
While there have been two confirmed cases of avian flu in humans, the likelihood of a widespread outbreak remains low. The CDC has identified that most human infections caused by avian influenza viruses worldwide are due to the Asian lineage of the bird flu virus (H7N9) and the highly pathogenic avian influenza A(H5N1) virus.
