As the world continues to grapple with the ongoing Covid-19 pandemic, the importance of hand hygiene has never been more evident. One of the most common methods of hand hygiene is the use of hand sanitizers, and one of the most well-known brands is Purell. But just how effective are these types of hand sanitizers against Covid-19?
The Role of Hand Hygiene in Infection Control
Proper hand hygiene is crucial in preventing the spread of infectious diseases, including Covid-19. By washing your hands with soap and water or using an alcohol-based hand sanitizer, you can effectively kill viruses and bacteria that may be on your hands.
The World Health Organization (WHO) recommends using an alcohol-based hand sanitizer with at least 60% alcohol content if soap and water are not readily available. This is because alcohol is effective at killing a wide range of viruses and bacteria, including CoVid-19.
The Effectiveness of Purell Against CoVid-19
Purell is an alcohol-based hand sanitizer that contains 70% ethyl alcohol. This concentration of alcohol is well within the range recommended by the WHO for effective hand hygiene against CoVid-19.
In addition to its alcohol content, Purell also contains other ingredients that help to kill viruses and bacteria, such as benzalkonium chloride and propylene glycol. These ingredients have been shown to be effective against a range of viruses and bacteria, including CoVid-19.
The Importance of Proper Hand Sanitizer Use
While Purell and other alcohol-based hand sanitizers can be effective against CoVid-19, their effectiveness is only as good as their use. In order to properly kill viruses and bacteria on your hands, it's important to follow these steps:
- Use enough hand sanitizer to cover all surfaces of your hands, including between your fingers and under your nails.
- Rub your hands together until they feel dry. This typically takes around 20 seconds.
- Do not wipe or rinse off the hand sanitizer before it has had a chance to dry.
- If your hands are visibly dirty or greasy, wash them with soap and water instead of using hand sanitizer.
The Connection to Ebola
The importance of proper hand hygiene in preventing the spread of infectious diseases is not limited to CoVid-19. In the past, the Ebola virus has also spread through poor hand hygiene practices.
In the 2014-2016 Ebola outbreak in West Africa, one of the main ways that the virus spread was through the improper handling of corpses. Funeral workers who came into contact with infected bodies without wearing protective gear were at high risk of contracting the virus.
By following proper hand hygiene guidelines and using alcohol-based hand sanitizers like Purell, the spread of infectious diseases can be effectively controlled.
In conclusion, hand sanitizers like Purell can be effective against CoVid-19 when used properly. Their alcohol content and additional ingredients help to kill viruses and bacteria on the hands. However, proper use is crucial for their effectiveness.
