Let’s address the elephant in the room; what is more effective in battling Covid, washing hands or using a hand sanitizer. Read on and find out which is better.
Is washing hands and using sanitizer equally good?
You must have heard the most important way to avert COVID infection is by washing hands with soap; be it a bar soap or a liquid soap and using an alcohol based hand sanitizer.

Use of a soap and water to rinse your hands eliminates all types of germs and some viruses too. A sanitizer gel contains alcohol concentration of at least 60% and will be effective only when it is used properly.Studies have shown that people generally don’t put on enough sanitizer gel or wipe it before it properly dries.
It takes about 30 seconds or less for the gel to dry completely but in some cases it may take about 100 seconds. What people do is to wipe the gel off with a paper towel instead of waiting for it to dry.

The reason was that the midwives weren’t involved in performing autopsies or other procedures and washed hand before performing childbirth.
According to some recent studies conducted among children, washing hands with soap reduce the rate of respiratory infection from 25-50%.
