Hand hygiene has always been regarded as the most crucial way of preventing the spread of infectious diseases. Hand sanitizers have gradually gained popularity among people as they provide an instant solution for removing germs from the hands. But the question remains; how effective are hand sanitizers compared to soap and water?
Hand sanitizers primarily contain ethyl alcohol, isopropyl alcohol, or benzalkonium chloride as their active ingredient. These alcoholic formulations work by breaking down the lipid membrane of viruses and bacteria on the skin’s surface. They’re effective in reducing the concentration of microbes on the hands but may not eliminate all of them.
On the other hand, soap and water not only reduce the number of microbes on the hands but can also remove dirt and other substances that may harbor these germs. Soap’s chemical structure enables it to interact with the lipid membrane and dissolve it. When the hands are rinsed with water, the soap and germs are then washed down the drain, leaving the hands clean.
According to the Centers for Disease Control and Prevention (CDC), washing hands with soap and water is the most effective way of reducing the spread of diseases like diarrhea, respiratory infections, and skin infections. The CDC recommends washing hands for at least 20 seconds, especially before eating, after using the toilet, after sneezing, and after touching high-traffic surfaces like doorknobs.
While hand sanitizers provide a convenient solution when soap and water are not readily available, they should not substitute regular handwashing. Care should be taken in the selection of hand sanitizers as some are ineffective in killing all types of germs, which can lead to the development of resistant strains.
In conclusion, both soap and water and hand sanitizers have their place in ensuring hand hygiene. Soap and water are the most effective way of removing germs from the hands, but hand sanitizers provide a convenient alternative in a pinch. Regular handwashing with soap and water should always be the first line of defense in preventing the spread of infectious diseases.
