California has confirmed its first case of bird flu in a child, marking a significant milestone in the ongoing H5N1 influenza outbreak. This is the first reported instance of a minor contracting the virus in the U.S. this year, bringing the total number of human cases to 55, according to the CDC.
First Bird Flu in Children: Mild Symptoms, Low Risk
The child experienced mild symptoms and was treated with antiviral medication. Initial tests showed low levels of the virus, and follow-up tests returned negative for H5N1 but positive for other respiratory viruses. All household members had symptoms but tested negative for bird flu.
The case is currently under investigation by California Department of Public Health to determine the source of exposure.
Stanford Experts Stress Caution for At-Risk Populations
Stanford infectious disease specialists are urging heightened awareness, especially for individuals working with livestock or in rural areas.
“We are seeing more cases linked to exposure to sick cows, and while human-to-human transmission is still rare, it’s important for people in high-risk areas to take preventive measures,” says Dr. Frank Giacobetti, an infectious disease expert at Stanford.
Preventive Measures to Minimize Risk
California health officials warn that H5N1 bird flu can spread through:
- Drinking raw milk or contact with droplets that touch the eyes, nose, or mouth.
- Breathing in dust or droplets containing the virus.
- Handling sick or dead animals.
Stanford Physician Advocate encourages healthcare providers and the public to take precautions, including wearing protective gear when handling animals and reporting symptoms immediately.
Ongoing Monitoring and Advocacy
California has reported 29 human cases of bird flu this year, primarily linked to infected cows. Other states, including Colorado, Texas, and Washington, have also seen confirmed cases. Federal and state officials continue to monitor the situation closely, with the public health risk still deemed low.
