Wearing loose clothing can help avoid extra pain from clothing rubbing against the rash. Avoid close skin-to-skin contact with others who have not had chickenpox, are ill, or who have a weakened immune system to avoid spread of the virus.
Skin biopsy, taking a piece of skin rash and looking at it under the microscope, is another possible way to diagnose herpes zoster. A culture of the biopsied tissue may be done if there are no intact blisters to culture. Also, viral DNA (deoxyribonucleic acid) may be detected using PCR (polymerase chain reaction) on the tissue taken from the biopsy. This test is expensive and not routinely used to diagnose shingles.

Individuals who never have had chickenpox and have not received the vaccine for chickenpox are susceptible to shingles virus infection. Consequently, shingles disease is contagious for chickenpox by transmission of the varicella-zoster virus (VZV) to these individuals. However, the shingles rash is not contagious in that a rash from one individual is unable to spread to another individual so the disease, shingles itself, is not directly contagious. Nevertheless, the disease of shingles can pass the virus from its active rash blisters directly to another individual (an adult, child, or baby) who can become infected with the varicella-zoster virus if the individual is not immune to VZV and develop chickenpox. The chickenpox infection can cause shingles in some individuals later in their life. Shingles, in this manner, may be considered to be indirectly contagious. Moreover, because varicella-zoster virus infection is commonly contagious in the form of chickenpox, and this infection can eventually lead to shingles development in some patients, it is fair for some researchers to say that shingles is indirectly contagious by the spread of chickenpox.
Varicella zoster virus (VZV) has a high level of infectivity and has a worldwide prevalence. Shingles is a re-activation of latent VZV infection: zoster can only occur in someone who has previously had chickenpox (varicella).
Talk with your healthcare provider if you have questions about shingles vaccine. Shingles vaccine is available in doctor’s offices and pharmacies. To find doctor’s offices or pharmacies near you that offer the vaccine, visit Zostavax or HealthMap Vaccine Finder.
The clinical appearance of shingles is usually sufficient for a doctor to establish the diagnosis. Diagnostic tests are not usually required. However, particularly in people with impaired immune function, shingles may sometimes not have the characteristic clinical pattern. In this situation, samples from the affected skin may be examined in a laboratory, either by culturing the tissue for growth of the virus or by identifying the genetic material of the virus.
If a pregnant woman, a person with a weakened immune system or a newborn baby comes into contact with someone who has chickenpox and they’ve never had it before, they need to see a GP as soon as possible. The GP can then prescribe the appropriate treatment.
Since the late 1990s, most children in the U.S. have received the varicella vaccine to protect against chickenpox. This vaccine uses a weakened strain of the varicella zoster virus that is less likely to settle into the body for the long haul.
Theoretically, it may be possible to spread VZV to other individuals during a zoster outbreak because VZV has been reportedly detected in saliva and secretions in individuals with chickenpox and/or shingles. However, there is little or no data about the frequency of secretion transmission. Such spread of VZV to others is considered to occur rarely.
Although DNA analysis techniques such as polymerase chain reaction (PCR) can be used to look for DNA of herpesviruses in spinal fluid or blood, the results may be negative, even in cases where other definitive symptoms exist. Notwithstanding these limitations, the use of PCR has resulted in an advance in the state of the art in our understanding of herpesviruses, including VZV, during the 1990s and 2000s. For example, in the past, clinicians believed that encephalitis was caused by herpes simplex, and that patients always died or developed serious long term function problems. People were diagnosed at autopsy or by brain biopsy. Brain biopsy is not undertaken lightly: it is reserved only for serious cases that cannot be diagnosed by less invasive methods. For this reason, knowledge of these herpes virus conditions was limited to severe cases. DNA techniques have made it possible to diagnose “mild” cases, caused by VZV or HSV, in which the symptoms include fever, headache, and altered mental status. Mortality rates in treated patients are decreasing.
For those who have already had chickenpox, there is also a shingles vaccine. The Food and Drug Administration approved the shingles vaccine for adults over the age of 50. The CDC recommend adults over the age of 60 who have a history of chickenpox get the vaccine. There is no maximum age for getting the vaccine.
Dooling said the majority of members of the working group supported the idea. They were concerned, she said, that if a preference wasn’t named, insurance companies might opt to reimburse for the cost of the cheaper vaccine — regardless of which is best. And it would require time-strapped doctors to try to figure out which vaccine to give their patients.
Once a person has had chickenpox, the virus lies inactive in nerve tissue. Years later, it may reactivate as shingles. The C.D.C. estimates that about one million cases are diagnosed in the United States each year.
At the commencement of the program, the interest in the vaccine was unprecedented. Early shortages have been addressed and there is now ample stock available to meet ongoing demand under the program.
In some cases, shingles can affect the nerves of the face, ears or eyes and cause complications. Complications include the development of facial paralysis, impaired vision and hearing. Another complications is called postherpetic neuralgia, in which the pain of shingles lasts for months or even years. People with compromised immune systems are at a higher risk for developing serious complications of shingles….more about Shingles »
This type of viral infection is characterized by a red skin rash that can cause pain and burning. Shingles usually appears as a stripe of blisters on one side of the body, typically on the torso, neck, or face.
A doctor is usually able to make a diagnosis of shingles based on its characteristic symptoms. A full medical history will be taken and the doctor may take a sample of the fluid from within the blister so that it can be tested in a laboratory for presence of the chickenpox virus.
Getting vaccinated can also help you avoid painful nerve complications from the disease. Although the shingles vaccine is approved by the FDA for people ages 50 to 59, the CDC recommends waiting until age 60 to get the vaccine. This is because it’s not clear how long immunity from the vaccine lasts. It appears to be most effective the first five years after getting it. Even if you’ve had shingles before, you can still get the vaccine to decrease the likelihood of a future reoccurrence of it.
Canada’s National Advisory Committee on Immunization has not yet made a recommendation for the use of the Shingrix vaccine in Canada. If you are interested in getting this vaccine, it is recommended that you speak with your health care provider for more information.
By preventing shingles, the vaccine also drastically reduces the overall incidence of severe nerve pain, a lasting complication for about one in three people who get shingles. GlaxoSmithKline said it tested the vaccine in more than 38,000 people.
In contrast, Shingrix is 97% effective against shingles for people between the ages of 50 and 69 and 91% effective for people 70 or older. It is 91% effective against postherpetic neuralgia for people 50 and older. These rates are based on evidence presented to the committee from clinical trials with over 38,000 total participants.

For some seniors, it can mean the difference between living independently and having to move into a long-term care facility because of its long-lasting effects, Livingstone said. Losing their independence is a huge issue for older people, she added.
People looking to receive the shingles vaccine now have two options. The Food and Drug Administration in 2017 approved Shingrix as the preferred alternative to Zostavax, which was approved in 2006. Both vaccines are approved for adults age 50 and older for the prevention of shingles and related complications, whether they’ve already had shingles or not.
Only people who have never had chickenpox are likely to be at risk of catching chickenpox from your shingles. People who have had chickenpox should be immune from catching it again. If the rash is in a covered area of skin, the risk of anyone with whom you are not in close contact catching chickenpox is very low.
Shingles, also known as herpes zoster, is a painful, itchy rash that develops on one side of the body and can last for two to four weeks. One in three Americans will develop shingles in their lifetime, with the risk increasing to half of adults over 85, according to the US Centers for Disease Control and Prevention.
For this reason, people affected by shingles should stay away from babies, children, pregnant women, people with a weak immune system, people who have not had chickenpox, or people who have not been vaccinated against chickenpox. Once a person develops chickenpox, he/she cannot contract the virus from others. The virus remains dormant in their body. However, people who have not had chickenpox, are at a risk of getting exposed to the virus, and developing chickenpox. Once infected, these people can develop shingles later in life.
“Shingles” comes from the Latin word, cingulum, meaning girdle, while “zoster” (another name for shingles) derives from the Latin and Greek words for girdle. As each name suggests, a band of blisters wraps around one side of the body, like a girdle, often around the waist, chest, stomach, back or buttocks. But it can also appear on one side of the face, around an eye or across the forehead. And it may even invade internal organs. The location of the blisters is related to the nerves affected by the reactivated virus.
