There are a plenty of hiding place for virus to stick. If you then touch your face, the virus can infect you. But there are two simple ways you can keep them away, soap and water, and hand sanitizer. It’s not best for any viral outbreak but best solution for covid. So which is better?
The corona virus that cause covid 19 is one of many viruses whose protective outer surface is made up of lipid bilayer. There lipids are pin shaped molecule whose heads are attracted to water means hydrophilic (water loving), and tails are repelled by it means hydrophobic (water hating). So in water rich environment, lipid naturally forms a shell, with heads outside and tails inside.
The actual process of destroying the virus happens in just one or two seconds. But doctors recommend at least 20 seconds of hand washing because of intricate structure of our hand. Soap and sanitizer need to get everywhere, including our palms, nails, fingertips and between our fingers to protect properly. And when it comes to corona virus outbreak, doctors recommend washing your hand with soap and water frequently. Both soap and sanitizer are similarly effective at killing the virus.
Soap and water has two benefits. It washes away any dirt which could otherwise hide virus particles. And it’s easier to fully cover your hand with soap and water for 20 seconds. On the other hand sanitizer is more convenient to use on the go. ( In the absence of sink and water). Hand sanitizer is just a emergency hands washing kit. When using sanitizer rub your hand together until they’re dry.
Unfortunately there are billions of people who don’t have access to clean drinking water which is a huge problem during this time.
Cleaning hand is very important because studies have found that we touch our face around 9 to 20 times per hour. Touching our face with uncleaned hand may be enough to infect ourselves.
