Research shows that enteroviruses can survive on banknotes for up to three days. That crumpled dollar you just gave your kid for the ice cream truck? Contaminated. Coins are slightly safer because copper is antimicrobial, but still—wash your hands after handling cash.
Doorknobs are the virus’s favorite hangout. A study found that HFMD can survive on a metal doorknob for four days if not cleaned. That’s why daycare centers have a “no doorknob licking” policy—which I assume is a real thing.
What About the Couch?
Soft surfaces are a mixed bag. On cotton t-shirts and towels, the virus dries out in a few hours. But on a microfiber couch or a fleece blanket? It might stick around for up to 24 hours. The texture traps moisture, giving the virus a cozy hideout.
And don’t forget the car seat. That thing is a petri dish on wheels. Studies suggest HFMD can survive on car seat fabric for up to 12 hours. So if your toddler just got over it, consider a deep clean—or just roll down the windows and let the wind have at it.
