Does hand sanitizer kill shingles virus? This is a question that often arises among individuals looking to protect themselves from the herpes zoster virus, which causes shingles. As hand sanitizers have become a staple in many people’s daily routines, it’s important to understand their effectiveness against this particular virus. In this article, we will explore the properties of hand sanitizers and their potential impact on the shingles virus.
Shingles, also known as herpes zoster, is a viral infection caused by the varicella-zoster virus (VZV). This virus is the same one responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nervous system, and it can reactivate later in life, leading to shingles. The symptoms of shingles include a painful rash, blisters, and itching, which can last for several weeks or even months.
Hand sanitizers are primarily designed to kill germs and bacteria on the skin, making them a popular choice for preventing the spread of infectious diseases. They contain alcohol or other antiseptic agents that disrupt the cell membranes of microorganisms, leading to their death. However, the effectiveness of hand sanitizers against viruses, such as the shingles virus, is a subject of debate.
Research suggests that hand sanitizers with at least 60% alcohol content can effectively kill many viruses, including the influenza virus and the norovirus. However, the effectiveness of hand sanitizers against the shingles virus is less clear. While some studies indicate that hand sanitizers can inactivate the VZV, others show mixed results.
A study published in the Journal of Antimicrobial Chemotherapy in 2012 found that hand sanitizers containing 62% alcohol were effective in killing the VZV within 15 seconds. However, this study was conducted in a laboratory setting and may not reflect real-world conditions. Another study published in the Journal of Infection in 2013 concluded that hand sanitizers were not as effective against the VZV as they were against other viruses, such as the influenza virus.
Despite the mixed results, it’s important to note that hand sanitizers are not a substitute for vaccination or antiviral medication in treating shingles. Vaccination is the most effective way to prevent shingles, while antiviral medication can help manage the symptoms and reduce the duration of the infection. However, hand sanitizers can still play a role in preventing the spread of the virus to others, especially in situations where immediate access to soap and water is not available.
In conclusion, while hand sanitizers may not be the most effective method for killing the shingles virus, they can still help reduce the risk of spreading the virus to others. It’s important to maintain good hygiene practices, such as washing hands with soap and water when possible, and to seek medical attention if you suspect you have shingles. Additionally, getting vaccinated against the varicella-zoster virus is the best way to prevent shingles and its complications.
