Does hand sanitizer kill coronavirus? This question has been on the minds of many people since the outbreak of COVID-19. With the pandemic spreading rapidly, it’s crucial to understand how effective hand sanitizers are in preventing the transmission of the virus. In this article, we will explore the efficacy of hand sanitizers in killing the novel coronavirus and provide you with the necessary information to make informed decisions about their use.
Hand sanitizers are alcohol-based solutions that are designed to kill germs and bacteria on the skin. They are often used as an alternative to handwashing when soap and water are not readily available. The primary active ingredient in hand sanitizers is usually ethyl alcohol or isopropyl alcohol, which are known for their ability to denature proteins and disrupt the cell membranes of microorganisms, effectively killing them.
When it comes to the novel coronavirus, scientific studies have shown that hand sanitizers containing at least 60% alcohol are effective in killing the virus. The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) recommend using hand sanitizers with a minimum of 60% alcohol content to reduce the risk of COVID-19 transmission.
The mechanism of action for hand sanitizers against the novel coronavirus is similar to that against other viruses. The alcohol in the sanitizer penetrates the lipid envelope of the virus, causing it to collapse and inactivate. This process disrupts the virus’s ability to replicate and spread to other cells.
However, it is important to note that hand sanitizers are not a substitute for handwashing with soap and water. While hand sanitizers can kill the virus on the skin, they do not remove all types of germs and may not be as effective in preventing the spread of other diseases. Washing hands with soap and water for at least 20 seconds is still the gold standard for preventing the transmission of the virus and other pathogens.
In addition, it is crucial to use hand sanitizers correctly. The CDC recommends applying the sanitizer to the palm of one hand, then rubbing it all over the surfaces of the hands until they feel dry. It is important to cover all surfaces of the hands, including the backs of the hands, between the fingers, and under the fingernails.
In conclusion, hand sanitizers containing at least 60% alcohol are effective in killing the novel coronavirus. However, they should not be used as a replacement for handwashing with soap and water. By understanding the proper use of hand sanitizers and combining it with good hand hygiene practices, individuals can significantly reduce their risk of contracting and spreading COVID-19.
