Bird Flu Warning Reduced in the USA

The H5N1 strain of highly pathogenic avian influenza (HPAI) has been present in wild birds worldwide and caused outbreaks in U.S. domestic birds and dairy cattle in 2024-2025.

While there were 70 humans infected with HPAI, and one related fatality, there was no human-to-human transmission of this serious virus.

However, since February 25, 2024, only six human cases have been reported.

As the number of infections has recently decreased, the U.S. Centers for Disease Control and Prevention (CDC) announced that it has streamlined H5N1 bird flu updates with routine influenza data and reporting cadences to reflect the current public health situation.

As of July 7, 2025, the following changes were made to this CDC webpage:

Data on the number of people monitored and tested for bird flu are reported on a monthly basis.

Data on highly pathogenic avian influenza (HPAI) detections in animals will no longer be reported on the CDC website. These HPAI data can be found on the U.S. Department of Agriculture's website.

Furthermore, the CDC will report any additional human cases of H5 bird flu here and in FluView.

While there are 'bird-flu' vaccines approved by the U.S. FDA, none were deployed in the USA during this outbreak.
