California Bird Flu Cases Raise Concerns

California has reported a third human case of bird flu among individuals in contact with infected dairy cattle, with two more possible cases under investigation. This brings the U.S. total to 16 cases among those exposed to dairy cows and poultry, raising concerns among scientists and officials.

On Wednesday, California confirmed a third human case of bird flu from contact with infected dairy cattle, while two more possible cases are under review. This development has increased the total U.S. human bird flu cases, linked to dairy cows and poultry exposure, to 16 this year.

In California, there appears to be no interpersonal transmission between confirmed and potential cases, pointing to animal-to-human virus spread, according to the state's Department of Public Health. A Missouri case, with no clear animal contact, also tested positive, adding to the concern.

The infection's spread to cattle in 14 states and the infection of farm workers has alarmed scientists and federal health officials due to the potential human risks involved. California suggests additional confirmations could follow from those in contact with infected cattle, all experiencing mild symptoms like eye irritation but requiring no hospitalization.
