California health officials have confirmed the state’s fourth human case of bird flu this year, linked to infected dairy cattle. Nationwide, 18 human cases have been reported in 2024, primarily among those exposed to sick livestock.
Bird Flu in California: New Cases Emerge
The four California cases occurred on separate dairy farms, with individuals experiencing mild symptoms such as eye redness and discharge. None of the affected individuals required hospitalization. The California Department of Public Health is investigating two additional potential cases.
Nationwide: Widening Impact
The virus has, meanwhile, been confirmed in dairy herds across 14 states, primarily affecting farm workers who had direct contact with infected animals. Although human-to-human transmission of bird flu remains rare, experts are, nevertheless, closely monitoring the virus for any signs of mutation or increased transmissibility.

Stanford infectious disease specialists urge those working with livestock to prioritize safety measures, including wearing protective gear and practicing strict hygiene.
“Though the general public’s risk is minimal, direct exposure to infected animals poses a significant risk. Early symptom recognition and reporting are critical,” says Dr. Andres Valdez, a Stanford public health expert.
