We might be fueling the next outbreak 🦠

Why does it feel like there’s always another outbreak? New research has some answers. Plus, bird flu reaches polar bears, frozen clams are linked to Hep A, and fall allergies complicate sick calls.

Best Question:

Are fall allergies a real thing, or are my employees yanking my chain? 


I’m sorry to report that fall allergies are all too real – and quite common. Certain allergens are more prevalent in the fall, when people are still spending time outdoors and exposed to different molds and pollen than other seasons. 
‍

But it’s also the start of respiratory virus season, so telling the difference can be tricky. Our best hint: itchy, watery eyes are unique to allergies, so if someone has those, it’s generally allergy-related. If an employee normally has allergy symptoms, and there’s nothing new or different about their symptoms this year, it’s safe to assume they’re seasonal allergies and they can continue to work.

It isn’t your imagination (or just that you read this briefing)... we really are seeing more outbreaks. The reasons why are complicated and interconnected, and humans may be playing a bigger role than we realize. Our friends at NPR dig into what’s driving the increase and what we can actually do about it.
