** It's been three months since the last reported human case of bird flu in the US, and experts are scratching their heads. While that might sound like good news, health officials aren’t ready to relax—they’re urging people to stay alert, wondering if this lull is just a temporary break or a sign of something else going on behind the scenes.

What This Mean: ** Bird flu outbreaks can be unpredictable, and a pause in human cases doesn’t necessarily mean the threat is gone. It could mean better containment, fewer infections in animals, or even gaps in testing and reporting. Either way, public health folks aren’t taking any chances—because when it comes to viruses, silence isn’t always reassuring.
