Avian flu (H5N1) is spiraling out of control in the US, prompting warnings of a potential pandemic. Nearly 1,000 dairy cow herds are affected, along with over 70 human cases, including one death. Millions of poultry have been culled, and egg prices have surged. While human-to-human transmission hasn't been confirmed, experts fear mutations could increase this risk. The Global Virus Network urges stronger surveillance, biosecurity, and vaccine development. Concerns exist over insufficient government response and funding, despite existing vaccine stockpiles and antiviral treatments.
