You’re probably using hand sanitizer wrong. Here’s the correct way, CDC says
Using hand sanitizer is recommended by experts to prevent the spread of COVID-19, but you may not be applying it correctly..
A new study published in the peer-reivewed journal, Emerging Infectious Diseases by the Centers for Disease Control and Prevention, found that using hand sanitizer for at least 30 seconds inactivated the coronavirus.
The study used sanitizer formulations approved by the World Health Organizations, containing either 80% ethanol or 75% isopropyl alcohol. The virus was found to be “efficiently inactivated” within 30 seconds of sanitizer use.
COVID-19 can be spread between humans, even when no symptoms are present, and to prevent the spread of the virus, “effective hand hygiene is crucial,” the CDC wrote in the study.
The CDC recommedns the alcohol-based hand sanitizer with more than 60% ethanol or 70% isopropanol to reduce “the number of pathogens” after interacting with patients.
To use the hand sanitizer properly, the CDC says to apply the gel to one hand and rub both hands together, making sure to rub the gel over hands and fingers until dry.
