Doctors observe increased shingles cases, potentially tied to COVID-19 and weaker immunity.

Shingles cases in Singapore are reportedly on the rise, with up to 30,000 individuals affected annually. Doctors suggest the increase could be linked to the nation’s ageing population and immune system impacts from the COVID-19 pandemic. While not life-threatening, the condition is causing concern due to its painful and often debilitating symptoms.

COVID-19’s Role in Shingles Reactivation

Dr Kelvin Goh, medical lead at United Primary Care Network, noted a pattern of shingles developing in patients post-COVID infection. A study by GSK in 2022 found those aged 50 or older were 15% more likely to develop shingles after contracting COVID-19.

Similarly, Dr Adrian Poh of HMI OneCare Clinic observed a 10% increase in shingles cases since the pandemic began, with the elevated risk persisting for up to six months post-infection.

What is Shingles?

Shingles, caused by the varicella-zoster virus, is a reactivation of the virus that causes chickenpox. It presents as red patches, painful blisters, and a rash usually affecting one side of the body. Unlike chickenpox, shingles is not contagious but can spread the virus to someone who has never had chickenpox.

Age as a Risk Factor

Age significantly increases susceptibility. According to Dr Shawn Vasoo from the National Centre for Infectious Diseases, international statistics reveal that:

20% of cases occur in people aged 50–59.
40% of cases occur in those over 60.
Half of those who live to 85 will develop shingles at some point.

The Cost of Vaccination

A shingles vaccine is available but costs nearly S$1,000 out of pocket. Despite its high price, Dr Goh recommends vaccination, especially for individuals over 50 or those with conditions like diabetes. The Ministry of Health is in discussions to negotiate better pricing but has yet to subsidize the jab.

Healthy Lifestyle Choices
Doctors recommend a proactive approach through regular exercise, balanced nutrition, and maintaining overall health to reduce the risk of shingles.

Early Prevention through Chickenpox Vaccination

Singaporean children can receive a free chickenpox vaccine. As shingles only affects individuals who have had chickenpox, this preventive measure offers long-term protection.

The rise in shingles cases underscores the importance of public health initiatives, especially for an ageing population. The condition highlights the lingering effects of the COVID-19 pandemic and the need for accessible vaccination options.

Shingles cases in Singapore have risen in recent years, with doctors citing age and post-COVID immune effects as contributing factors. Vaccination and healthy living are key preventive measures. However, the high cost of the shingles vaccine poses challenges for broader accessibility.
