So, how long does the flu last in the air? Up to three hours in aerosol form. That’s the headline.
But here’s the real takeaway: prevention is easier than you think. Ventilate. Humidify. Mask up if you’re feeling gross. Please don’t go to a party if you’re sneezing like a cartoon character.
You can’t control every particle in the world. You can control whether you’re the one launching a three-hour airborne ghost of flu past.
Now go grab a cup of tea and open a window. Your future, non-sick self will thank you. And if anyone asks why you’re airing out the house in January? Just tell them you’re conducting a science experiment. They’ll get it. Eventually.
