Seven percent of dairy farm workers in two states had evidence of a recent infection with highly pathogenic avian influenza, according to a new report published Thursday.

The United States Department of Agriculture this week confirmed the first case of highly pathogenic H5N1 avian influenza in a U.S. pig, raising concerns about the potential health risk to humans.

A dairy farm worker in Colorado became the fourth person to test positive for avian influenza in the ongoing outbreak affecting dairy cows in the United States, the CDC announced Wednesday.

Hay fever was less common among children who lived on a farm and consumed unprocessed cow’s milk than among other children in rural areas, according to a study in The Journal of Allergy, Asthma and Clinical Immunology: In Practice.

Childhood on a farm protected against allergic rhinitis throughout young adulthood, whether or not children stayed on the farm through puberty, according to a study published in The Journal of Allergy and Clinical Immunology.
