Nevada dairy worker tests positive for H5N1
A dairy farm worker in Nevada has tested positive for H5N1, marking the first human infection identified in the state. The worker is exhibiting symptoms that include red, inflamed eyes, or conjunctivitis. The U.S. Centers for Disease Control and Prevention (CDC) is currently working to confirm the initial positive test result. There is concern regarding whether this case is associated with the documented H5N1 2.3.4.4b D1.1 strain and represents a human spillover from cattle.
Scientists are closely monitoring the new infections in Nevada, as genetic sequencing from the affected cattle has indicated that they belong to a subtype of the H5N1 virus, specifically D1.1, which has been linked to two severe human infections in North America, including one fatality.
