Nevada just confirmed its first human case of avian flu from infected cattle. Nevada’s first case was found in Churchill County, the Central Nevada Health District announced on Monday.

Federal health officials say a dairy worker in Nevada has been infected with a new type of bird flu that’s different from the version that has been spreading in U.S. herds since last year.

Bird flu remains a growing problem across the U.S., and many of us have questions about how serious it is and how worried we should be.
