Health experts are sounding the alarm as bird flu spreads across all 50 U.S. states, infecting over 1,000 cattle herds and causing more than 70 human cases, including the first confirmed death.

The H5N1 virus, now present in wild animals and even raw milk, is being described as a slow-motion pandemic with the potential to mutate into a human-transmissible strain.

Despite the growing threat, experts warn the U.S. response has been disorganised, with lax testing and limited federal oversight.

The Global Virus Network is urging governments to strengthen surveillance, biosecurity, and vaccination efforts before it’s too late.

Scientists say time is running out to prevent a crisis on the scale of COVID-19.
