According to the Centre for Disease Control and Prevention (CDC), thoroughly washing hands is still the best way to steer clear of the novel coronavirus, reports CNN.
But the hand washing has to be done right. Here's the CDC's official hand-washing how-to.
Wet hands with clean, running water. Turn off the tap and soap up your hands. Soap is more effective at removing germs than water alone.
Work the soap into a lather by rubbing both hands together. Lather soap onto the backs of both hands, in between the fingers and under the nails.
Lathering causes friction, which strips pesky germs and dirt from the skin.
Scrub both hands for at least 20 seconds. The happy birthday song can be sung or hummed twice to keep track of time.
Washing hands for at least 20 seconds has been shown to remove more microbes than washing for shorter periods does.
Rinse both hands well under clean, running water.
The germs from both hands has been lifted off. Clean water flushes away the germs.
Dry both hands using a clean towel or air-dry them.
Wet hands easily transfer viruses. Drying them off lessens that risk.
Soap and water are the best defences against viruses, while hand sanitizer is a lesser effective substitute if you access to clean water is compromised.
Pumping a small glob of sanitizer on one hand and rubbing them together for about 20 seconds does a similar job.
However, hand sanitizers do not get rid of dirt, chemicals or a few types of germs, but they are better than nothing.
