The contaminated individual was identified after growing conjunctivitis, or pink eye. It’s solely the second-ever human case of chook flu within the U.S.; the primary was a poultry farm employee who was contaminated in 2022 whereas culling contaminated birds and recovered after experiencing solely delicate fatigue.

🥛 What does it imply for our meals and milk?
Bird flu has been detected in egg-laying chickens and dairy cows at a handful of U.S. farms. It has additionally been present in unpasteurized milk.

Antiviral medication will also be used to deal with chook flu, though the CDC notes that some variations of chook flu first present in Asia aren’t as responsive to those remedies.
Dr. Arnold Monto, a professor emeritus of epidemiology on the University of Michigan and member of the FDA’s vaccine committee, tells Yahoo Life that the U.S.’s chook flu vaccines require adjuvants, substances that enhance human’s immune responses. An official with the Department of Health and Human Services (HHS) additionally informed the Washington Post that elements for the vaccines are being examined, and it could doubtless take weeks to months for them to be prepared for widespread distribution. Monto provides that the vaccine would additionally doubtless be given to solely these at excessive danger — poultry and dairy farm staff — since there’s no proof that chook flu spreads from amongst people.
