Avian Flu spreads to poultry and mammals

The U.S. has reported its first fatal H5N1 avian flu infection, involving a Louisiana resident over 65 with underlying health conditions. Officials confirmed the patient likely contracted the virus through contact with backyard poultry and wild birds. No other related cases have been found.

The H5N1 flu has been linked to 66 human infections in the U.S. since 2024. Most cases are mild, but a new genotype from wild birds has resulted in severe cases, including one in Louisiana and another in Canada involving a recovering teenager.

Alongside human cases, the USDA’s Animal and Plant Health Inspection Service (APHIS) has confirmed H5N1 outbreaks in poultry across five states.

Delaware reported its first outbreak since 2022, with 125,000 birds affected. Additional outbreaks have been noted in California, Michigan, and backyard flocks in Arkansas and Idaho.

Animal cases are increasing, particularly in domestic and wild cats. Reports include infected cats in California, Oregon, and Minnesota, along with wild species like bobcats and mountain lions in Colorado and Nevada. 

“This virus’s widespread impact on animals requires urgent attention to contain its spread and safeguard public health,” experts warn.

The rising spread of H5N1 across species underscores the need for continuous surveillance, safety measures, and public awareness.
