Here’s where it gets really fun. You can be contagious before you even have a fever. Before your nose runs. Before you feel like garbage. You’re patient zero, and you’re about to go grocery shopping.
This is why the flu spreads like wildfire. Healthy-looking people are walking around, touching produce, and sharing your air. It’s not their fault. They don’t know yet.
So, When Should You Freak Out?
Don’t panic after one sneeze. But do pay attention around the 36- to 48-hour mark. If you were exposed Monday morning, Wednesday afternoon is your danger zone. By Thursday? You’re probably safe.
If your throat starts feeling scratchy, or your eyes get heavy, start hydrating. Call your mom to complain. Cancel your plans. The incubation period is ending, and the main event is about to begin.
