Shingles, or herpes zoster, is a painful skin rash that happens when the chickenpox virus becomes active again in the body. Though it can affect anyone who has had chickenpox, it is more common in older adults and those with weakened immune systems.
In Singapore, an estimated 30,000 new cases of shingles occur each year (National Centre for Infectious Diseases [NCID]). Some doctors have also reported a 10% increase in cases over the past two years, possibly due to an aging population and the impact of COVID-19 on immune health (CNA).
In this article, we’ll dive deeper into what shingles is, who’s most at risk, and answer some common questions about the shingles vaccine.

What is Shingles
Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. After recovering from chickenpox, the virus remains inactive in the body and can reactivate later in life, causing shingles.
Who is at Risk?
Certain groups are more likely to develop shingles:
- Adults aged 50 and above
- Individuals with weakened immune systems
- Those who have had chickenpox
Symptoms of Shingles
The early symptoms of shingles may include:
- Tingling or burning sensation in a specific area of the body
- Fatigue
- Fever and headaches
As the condition progresses, a painful rash often appears. This rash usually starts as red patches and then develops into fluid-filled blisters. These blisters tend to cluster on one side of the body or face and can last for about two to three weeks. Over time, the blisters may burst, form scabs, and gradually heal on their own.
How does shingles look like?
Shingles pictures often show the rash following nerve pathways, commonly around the torso or face.
Is Shingles Contagious?
While shingles is less contagious than chickenpox, it can still be transmitted to individuals who have not previously had chickenpox or received the chickenpox vaccine.
How Can You Prevent Shingles?
Vaccination is the best way to reduce the risk of shingles and its complications. The shingles vaccine is clinically approved and highly recommended for older adults.
Who is eligible for the shingles vaccine?
According to the National Adult Immunisation Schedule (NAIS), the vaccine is recommended for individuals aged 60 and older, as well as immunocompromised adults between the ages of 18 and 59.
Possible Side Effects of the Shingles Vaccine:
Common side effects include redness, swelling, or pain at the injection site. Some individuals may also experience headaches, muscle aches, or fatigue.
Shingles Treatment Options
If you develop shingles, early treatment is essential. Antiviral medications can help ease symptoms and shorten the duration of shingles. Pain relief and home remedies may also help manage discomfort.

Common FAQs About Shingles Vaccination
| Should I get the shingles vaccine if I never had chickenpox? |
|---|
|
Yes, as the vaccine can help protect against the virus even if you are uncertain about past chickenpox exposure. |
| Does the chickenpox vaccine prevent shingles? |
|---|
|
While the chickenpox vaccine reduces the risk of shingles, it does not eliminate it entirely. Therefore, getting the shingles vaccine is still recommended for stronger protection, especially as you age. |
| Can I get shingles after the Shingrix vaccine? |
|---|
|
While uncommon, shingles can still occur after vaccination, but symptoms are generally less severe. |
| How long is shingles contagious? |
|---|
|
It remains contagious until the blisters scab over. |
| Is shingles contagious through saliva? |
|---|
|
No, shingles typically spreads through direct contact with the fluid from blisters. |
| Is shingles contagious by touch or airborne? |
|---|
|
Shingles does not spread through the air. It spreads through direct contact with fluid from the blisters. Individuals who have never had chickenpox or the chickenpox vaccine can contract chickenpox, not shingles, if they come into contact with the virus from shingles blisters. |
