(NBC NEWS) — Many of us are depending on hand sanitizer to protect against coronavirus.
But a new study suggests most people are coming up short!
Researchers from the Centers for Disease Control found rubbing in hand sanitizer for exactly 30 seconds kills COVID-19.
But anything less can leave traces of active virus leaving you vulnerable to infection.
So a few things to remember.
Always use sanitizers with an alcohol content of 70-percent or more.
Rub in a generous amount for a full 30 seconds about the time it takes to sing happy birthday three times.
And be sure to get between your fingers and on the backs of your hands.
