Should we worry about bird flu in the US?

How worried should we be about bird flu spreading to humans in the US? Are rising bird flu numbers the beginning of the next pandemic? On GZERO World with Ian Bremmer, New York Times science and global health reporter, Apoorva Mandavalli says that now is the time to start taking bird flu more seriously. The virus, known as H5N1, has been circulating in the US since 2024 in poultry and dairy cattle, but fears are growing about its spread to humans after the first bird flu death was reported in Louisiana last month. One big reason for that is that the flu virus is very good at adapting, picking up characteristics that keep it spreading. With Robert F. Kennedy Jr. set to lead the US health department, Mandavilli worries about our ability to deal with a bird flu epidemic, especially given his opposition to mRNA vaccines and endorsement of raw milk, which can harbor bird flu virus, posing serious risks to public health.

“Surveillance has been just really, really poor. We don’t actually know what this virus is doing, how it’s evolving, how widely it’s spread,” Mandavilli says, “That first death was quite a wakeup call.”
