If confirmed by the CDC, these cases would increase the national total of human infections to 60, with 58 already reported in various states.

The Arizona Department of Health Services (ADHS) has confirmed the state’s first human cases of H5 avian influenza. The two individuals were exposed to infected poultry at a commercial facility in Pinal County. They experienced mild symptoms, received treatment, and have since recovered.1
The avian influenza virus has been detected in Arizona, with cases reported at a commercial poultry farm in Pinal County and a backyard flock in Maricopa County. Human infections typically occur through direct exposure to sick or dead animals or their environments, particularly when the virus enters the body via the eyes, nose, mouth, or inhalation.1
ADHS is taking proactive steps to monitor the situation in response to these cases. The state is collaborating with local, state, and federal partners to track avian flu in both animals and individuals working closely with poultry and dairy animals. Protective gear has been distributed to farm workers, and testing and treatment options are being made available to those exposed to the virus.1

If confirmed by the CDC, these cases will bring the national total of human infections to 60, with 58 already reported across multiple states.

"Public education is key in preventing further spread," said ADHS officials. "We are working to ensure that individuals have the information they need to stay safe and understand how to protect themselves from potential exposure."1
Currently, 58 human cases of avian influenza have been confirmed across multiple states, with most cases linked to exposure from poultry and cattle. The breakdown by exposure source is as follows:2
California: 32 cases (31 from cattle, 1 from unknown sources)
Colorado: 10 cases (9 from poultry)
Michigan: 2 cases (both from cattle)
Missouri: 1 case (from an unknown source)
Oregon: 1 case (from poultry)
Texas: 1 case (from cattle)
Washington: 11 cases (all from poultry)
Symptoms of bird flu in humans can include fever, cough, sore throat, diarrhea, muscle aches, fatigue, difficulty breathing, and pneumonia, with severe cases potentially leading to death. The virus spreads primarily through contact with infected animals or their bodily fluids, including feces, feathers, and saliva. People can become infected by inhaling contaminated dust or droplets, touching contaminated surfaces, or consuming raw (unpasteurized) milk from infected cows.2
To reduce the risk of infection, workers should use personal protective equipment (PPE) such as goggles, NIOSH-approved respirators, gloves, coveralls, and boots when handling animals that could be infected with H5N1. Workers are also advised to wash their hands thoroughly after handling animals, animal waste, or raw dairy products.3
In conclusion, Arizona’s first confirmed human cases of H5 avian influenza underscore the need for vigilance and preventive measures. Health authorities are monitoring the situation and ensuring that those at risk have access to protective gear, testing, and treatment. As the national total increases, public awareness and safety protocols are key to limiting further spread of the virus.
