avian influenza. This announcement follows the recent revelation by the United States Department of Agriculture (USDA) of avian flu outbreaks in specific dairy cow herds in Texas just a week ago. Human cases of the H5N1 subtype avian influenza, commonly known as H5N1 bird flu, are rare, and the CDC noted that this is only the second reported case in the U.S.

The first case occurred in Colorado in 2022. Certain flu viruses primarily impact humans, while others are predominantly found in animals. Avian viruses typically originate in wild aquatic birds such as ducks and geese, and then transmit to domesticated poultry like chickens.

The current focus is on the bird flu virus Type A H5N1, which was initially detected in 1959. Like many viruses, it has undergone evolutionary changes, giving rise to newer strains. The symptoms are similar to those of other types of flu, such as coughing, body aches, and fever.

While some individuals may not exhibit noticeable symptoms, others may experience severe pneumonia, which can be life-threatening. Dr. Mandy Cohen, director of the Centers for Disease Control and Prevention, emphasized to The Associated Press on Wednesday the seriousness with which the agency regards the bird flu situation.

She pointed out that although the virus has been extensively studied, its presence in cattle heightens concern. Cohen highlighted the necessity for precautions among farmworkers handling cattle, not just those working with birds. Encouragingly, she noted, "It's not a new strain of the virus," emphasizing that the CDC has been studying and preparing for avian flu for two decades.
