But when we are stuck in a situation where soap and water are not available then using alcohol-based hand sanitizer is the second-best option to kill germs and bacteria thriving on your hands.

When washing hands with soap and water, we have to rub our hands together for 20 seconds to kills all the germs and chemicals. Turns out, when using hand sanitizer you have to rub your hands for more than that time.
As per the CDC, sanitizers take about 30 seconds to kill germs and bacteria. So, you must rub your hands for that long time to reduce the risk of getting infected.

Don't hand sanitizers evaporate in less than 30 secs ?

Is this something like WHO saying that asymptomatic Covid-19 patients need no isolation as they rarely spread the disease?
