Shingles, also known as herpes zoster, is a viral infection that causes painful rashes and blisters on the skin. It is caused by the varicella-zoster virus, the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in their body, typically in the nerve cells. Years later, the virus can reactivate, causing shingles. One common question that people ask is whether shingles can be spread by touching surfaces. In this article, we will explore the connection between shingles and surface contact, shedding light on how the virus spreads and what precautions you should take.
What is Shingles?
Shingles is a viral infection that mainly affects older adults and those with weakened immune systems. The initial infection is usually chickenpox, which is highly contagious. Once you recover from chickenpox, the virus doesn’t disappear but instead lies dormant in your nervous system. Shingles occur when this dormant virus reactivates later in life, often due to a weakened immune system or stress.
The main symptom of shingles is a painful rash, which typically appears as a stripe or cluster of blisters on one side of the body. Other symptoms may include fever, headache, fatigue, and itching. The pain can be severe, even before the rash appears. This condition is usually temporary, but in some cases, it can lead to long-term nerve pain called postherpetic neuralgia.
How Does the Virus Spread?
Shingles is not directly contagious like chickenpox. The varicella-zoster virus that causes shingles can only spread when a person with the condition has active blisters. When these blisters rupture, they release fluid containing the virus. The virus can then be passed on to others who have never had chickenpox or been vaccinated against it, through direct contact with the fluid from the blisters.
However, it is important to note that the varicella-zoster virus can only be spread through contact with the fluid from the blisters. This means that casual contact, such as touching surfaces where someone with shingles has been, does not pose a risk of spreading the virus.
Can You Get Shingles from Touching Surfaces?
The short answer is no, you cannot get shingles simply by touching surfaces. The virus that causes shingles, the varicella-zoster virus, does not survive long on surfaces. It needs direct contact with the fluid from the blisters or a person’s skin for transmission to occur. This is important because it helps clear up confusion about how shingles spreads.
While it is theoretically possible for the varicella-zoster virus to be transferred to a surface from an infected person, the virus is not capable of surviving for long periods outside the body. Environmental factors, such as heat, light, and dryness, can rapidly reduce the virus’s ability to infect another person. Therefore, simply touching a surface that has been in contact with someone who has shingles will not result in infection.
How Does the Virus Spread Between People?
As mentioned earlier, the varicella-zoster virus primarily spreads through direct contact with the fluid from the shingles blisters. If someone with shingles touches their rash or blisters, the virus can be transferred to their hands. If they then touch another person, they could pass on the virus. This is why people with shingles are advised to cover the rash and avoid touching it to prevent spreading the virus.
Additionally, the virus can spread through close contact with someone who is not immune to chickenpox. People who have never had chickenpox or the chickenpox vaccine can develop chickenpox after coming into contact with the fluid from shingles blisters. Once someone has chickenpox, they cannot catch shingles until the virus reactivates later in life.
Precautions to Prevent the Spread of Shingles
Even though you cannot get shingles from touching surfaces, it is still important to take precautions to avoid spreading the virus to others. Here are a few steps you can take if you have shingles or are caring for someone who has it:
1. Avoid Direct Contact with the Rash
One of the most effective ways to prevent the spread of shingles is by avoiding direct contact with the rash or blisters. If you have shingles, keep the rash covered with loose clothing or bandages. Avoid scratching the rash to prevent the fluid from coming into contact with other parts of your body or the environment.
2. Wash Your Hands Regularly
Good hygiene is essential in preventing the spread of the varicella-zoster virus. Wash your hands frequently, especially after touching the rash or any items that may have been in contact with the virus. Use soap and water and scrub for at least 20 seconds. Hand sanitizers with at least 60% alcohol can also be useful if soap and water are not available.
3. Avoid Contact with Vulnerable Individuals
Certain people are at higher risk of developing severe complications from chickenpox or shingles. These include:
- Pregnant women who have not had chickenpox or the vaccine
- Newborns who have not yet been exposed to chickenpox
- Immunocompromised individuals, such as those undergoing chemotherapy or with HIV/AIDS
- Older adults, especially those over 60, who are more likely to develop postherpetic neuralgia
If you have shingles, try to avoid contact with these individuals until your rash has fully crusted over and is no longer infectious.
4. Disinfect Surfaces Regularly
While touching surfaces doesn’t typically spread shingles, it’s still a good idea to clean and disinfect areas that may have been in contact with the rash or blisters. This includes towels, bed linens, and any surfaces that might have come into contact with the rash. Use disinfectant wipes or sprays to clean commonly touched surfaces like doorknobs, light switches, and countertops.
5. Keep Your Immune System Strong
Since shingles is often triggered by a weakened immune system, it’s important to maintain overall health. Eat a balanced diet, exercise regularly, and get plenty of rest to help keep your immune system functioning well. If you are over 50, you may want to consider getting the shingles vaccine, which can reduce the risk of developing shingles and its complications.
Can You Catch Shingles If You’ve Had Chickenpox Before?
Yes, if you’ve had chickenpox before, you carry the varicella-zoster virus in your body. The virus can reactivate years later, causing shingles. Having had chickenpox does not make you immune to shingles. In fact, shingles only occurs in people who have already had chickenpox. The risk of developing shingles increases with age, especially after 50, as the immune system weakens over time.
The shingles vaccine is recommended for older adults, even if they’ve already had chickenpox, as it can help prevent the reactivation of the virus and reduce the severity of shingles if it does occur.
Conclusion
In conclusion, shingles is not spread by touching surfaces. The varicella-zoster virus that causes shingles requires direct contact with the fluid from the rash or blisters to be transmitted. Though touching a surface contaminated with the virus is unlikely to cause infection, it’s still important to take precautions to prevent the spread of the virus, especially to vulnerable individuals. By practicing good hygiene, avoiding direct contact with the rash, and taking steps to maintain your immune health, you can reduce the risk of transmitting shingles to others.
If you suspect that you have shingles, it is important to consult a healthcare provider for proper diagnosis and treatment. Early treatment can help reduce the severity of symptoms and the risk of complications.
