New survey shows nearly 70% of older adults in Singapore underestimate their risk of shingles; only 1 in 4 plans to consult their doctor on prevention
- Published in News from Asia
- A survey by Ipsos, sponsored by GSK, found that while 63% of adults aged 50 years or over in Singapore were aware of shingles, only 29% recognised that 1 in 3 may develop the disease in their lifetime.
- Less than half of respondents (44%) understood that shingles can increase the risk of stroke or heart attack; fewer (36%) knew that the risk for shingles further increases amongst those with underlying chronic health conditions such as chronic obstructive pulmonary disease (COPD), cardiovascular disease, or diabetes.
- Only 1 in 4 intended to discuss shingles prevention with their doctor within the next three months.
- Survey findings reinforce need for deeper understanding of shingles and to encourage older adults to consult their doctors on shingles prevention.
SINGAPORE - Media OutReach Newswire - 22 October 2025 - A new survey1 highlighted that 63% of older adults aged 50 years or over in Singapore recognised shingles, also known as herpes zoster, as a serious disease. However, two out of three underestimated their personal risk of contracting the disease. Despite the high awareness in this group, only 25% intended to discuss shingles prevention with their doctor within the next three months.
The survey further showed that only 44% of respondents understood that those who have had shingles are at a significantly higher risk of heart attack (+59%) and stroke (+35%) compared to those who have not had shingles.2
The survey also found that 36% of respondents know that the risk for shingles further increases amongst those with underlying chronic health conditions.3
A local study has earlier reported that more than 85% of Singaporean adults aged 60 years or over have declared having been diagnosed with at least one chronic health condition.4 The five most reported chronic health conditions amongst older adults in Singapore in 2020 were: high blood pressure or hypertension; high blood cholesterol or lipids; joint pain, arthritis, or nerve pain; high blood sugar or diabetes; and renal/kidney or urinary tract ailments.4
The "Shingles Awareness Tracking Survey" conducted by Ipsos, on behalf of GSK, surveyed 200 adults aged 50 years or over in July of this year to measure the level of public understanding and perceptions of shingles in Singapore.1
In the survey, only 48% of respondents understood that the virus which causes chickenpox during childhood, the varicella-zoster virus (VZV), can remain in the body and reactivate later in life to cause shingles. 5,6
VZV is present in most adults aged 50 years or over7 and may reactivate with advancing age.8 As people age, the strength of the immune system response to infection wanes, increasing the risk of developing shingles.9
Dr Asok Kurup, from the Infectious Diseases Care Department at Mount Elizabeth Hospital, explained, "In Singapore, more than 90% of adults aged 50 years or over carry this virus.10 This means one in three will eventually develop shingles."9
The survey also showed that at least 70% of respondents could identify the common symptoms of shingles such as a painful rash at the affected site.5 Moreover, at least 60% understood that the disease could lead to long-term, potentially permanent, complications such as nerve pain, also known as Postherpetic Neuralgia (PHN), that can last for years.11
PHN is the most common complication of shingles. It affects approximately 10% to 18% of people with the disease, and the risk of PHN increases with age.12
To help encourage more older adults to consult their doctors about shingles, GSK launched an initiative in October that hired and trained seniors aged 50 years or over to become community ambassadors for shingles awareness. These ambassadors have been participating in various wellness events and activities at ageing centres, where they share personal stories and encourage their peers to go and speak with their doctor about the disease and the ways to prevent it.

Ms Claire, who is in her forties, shared in a conversation with GSK, "When my father had shingles for the second time around, he was in his 60's.13 And he came out one day, saying 'Look, take a look at this,' and there were rashes on his forehead and a little bit on his torso.13 He said that there was stinging pain,11 and I could feel that he was undergoing this pain because he did not wipe his face and wash. He would wake up a few times at night because of the pain on his forehead and body."

"While we see that overall awareness continues to improve, we need to further strengthen the understanding of our communities on the increased risk of shingles amongst adults aged 50 years or over — and it can be prevented. Go speak with your doctor," said Dr Asok.
