Does hand sanitizer help against virus? This is a question that has been widely debated, especially during the COVID-19 pandemic. With the increasing awareness of hygiene and the importance of preventing the spread of infectious diseases, many people have turned to hand sanitizers as a quick and convenient solution. However, the effectiveness of hand sanitizers against viruses, particularly against the novel coronavirus, remains a topic of discussion. In this article, we will explore the role of hand sanitizers in combating viruses and provide insights into their efficacy.
Hand sanitizers are alcohol-based solutions that are designed to kill germs on the skin. They are particularly effective against bacteria and some viruses, including influenza and norovirus. The World Health Organization (WHO) recommends the use of hand sanitizers with at least 60% alcohol content to reduce the risk of infection. When it comes to the novel coronavirus, hand sanitizers with a higher alcohol concentration, such as 70% or 75%, are more effective in killing the virus on the hands.
However, it is important to note that hand sanitizers are not a substitute for proper hand hygiene. Washing hands with soap and water for at least 20 seconds is still the gold standard for preventing the spread of viruses. Hand sanitizers should be used when soap and water are not readily available. In situations where hand sanitizers are the only option, it is crucial to use a sufficient amount and rub it thoroughly into the hands until dry.
While hand sanitizers can help reduce the risk of infection, they may not be effective against all viruses. For example, some viruses, such as norovirus, may survive on surfaces for longer periods, and hand sanitizers may not be as effective in killing these viruses. In such cases, it is important to practice good hygiene habits, such as washing hands frequently and using hand sanitizers as a complementary measure.
Moreover, the effectiveness of hand sanitizers can be influenced by various factors, including the quality of the product, the amount used, and the duration of use. It is essential to choose a reputable brand and follow the instructions provided on the product label. Additionally, hand sanitizers should be stored in a cool, dry place and used within the recommended shelf life to maintain their effectiveness.
In conclusion, hand sanitizers can be a useful tool in preventing the spread of viruses, particularly when soap and water are not available. While they are not a complete substitute for proper hand hygiene, they can play a significant role in reducing the risk of infection. It is important to use hand sanitizers correctly and in conjunction with other hygiene practices to ensure the best possible protection against viruses.
