Shingles, also known as herpes zoster, is a viral infection that causes a painful rash.
Shingles is caused by the varicella-zoster virus (VZV), which is the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains in the body in an inactive state within the nervous system. Later in life, the virus can reactivate and cause shingles. It is not fully understood why the virus reactivates, but it is thought to be related to a weakened immune system or aging. Shingles is not caused by a new infection with VZV, but rather by reactivation of virus that was already present in body.
Hospitals in India reportedly document over one million cases of shingles annually. Approximately one out of every three individuals will develop shingles at some point in their life after the age of 50. The risk of developing shingles increases with age, so the likelihood of experiencing the infection becomes more significant as individuals get older.
One of the most common and severe complications of shingles is postherpetic neuralgia (PHN). PHN causes severe pain in the areas where the shingles rash occurred and is experienced by about 10 to 18% of people who develop shingles. The likelihood of experiencing PHN also increases with age.
Shingles is a painful skin rash that usually appears on one side of the face or body. The rash is made up of fluid-filled blisters that scab over within 7 to 10 days and typically clear up within 2 to 4 weeks.
Before the rash appears, people may experience pain, itching, or tingling in the area where it will develop. This can happen several days before the rash appears.
The rash usually occurs in a single stripe around the left or right side of the body. However, in some cases, the rash can affect one side of the face, including the eye, which can lead to vision loss. In rare instances, especially in individuals with weakened immune systems, the rash may be more widespread & look like a chickenpox rash.
Other common symptoms of shingles include:
Shingles can be a very painful and uncomfortable condition, but it is usually not life-threatening. However, in some cases, it can cause complications that may require medical attention. These include:
It is important to seek medical attention if you suspect you have shingles, especially if you are at higher risk for complications such as those with weakened immune systems or over the age of 50.
Shingles itself is not contagious. It can only be transmitted through direct contact with the fluid from the blisters, and only if the person comes into contact with the fluid before it crusts over. Once the blisters crust over, the risk of transmission is significantly reduced.
Shingles can be treated with antiviral medications, which can help reduce the severity and duration of the symptoms. These medications are most effective when taken within 72 hours of the rash appearing. Pain relievers, such as acetaminophen and ibuprofen, may also be recommended to help relieve pain and discomfort.
In addition to medication, other treatments for shingles may include:
Avoiding certain triggers: Some people find that certain triggers, such as stress, sunlight, or certain foods, can worsen their shingles symptoms. Avoiding these triggers may help reduce the severity of the symptoms.
Yes, shingles can be prevented through vaccination.
The Indian Medical Association (IMA) and Centres for disease control & prevention (CDC) recommends that adults aged 50 years and older receive the shingles vaccine, regardless of whether they have had shingles in the past.
Adults 50 years and older should get two doses of Shingrix, separated by 2 to 6 months.
The shingles vaccine is highly effective at preventing shingles and its complications. The shingles vaccine is more than 90% effective at preventing shingles in people who receive the recommended two doses. It is also effective at reducing the risk of postherpetic neuralgia, a painful complication that can occur after shingles. Even if someone who has been vaccinated still gets shingles, the vaccine can help make the symptoms less severe and reduce the risk of complications.
Yes, the shingles vaccine can still be given to someone who has already had shingles. The vaccine can help to reduce the risk of getting shingles again. If you have already had shingles, you aren’t immune from getting it again! Shingles can occur more than once in a lifetime and already having the infection does not protect you against future infections. If you recently recovered from shingles, we recommend you wait until your rash and symptoms have resolved before getting the vaccine.
The most common side effects of shingles vaccines are:
These side effects are usually mild and go away on their own within a few days. In very rare cases, serious side effects may occur, such as an allergic reaction. It's important to discuss any concerns about side effects with your healthcare provider before getting the vaccine.
You can get the shingles vaccination by making an appointment with your doctor.
