‘Infodemic’ risks jeopardising virus vaccines

Published

As early as February, with the global pandemic spreading fast, the World Health Organization issued a warning about an “infodemic”, a wave of fake news and misinformation about the deadly new disease on social media.

Now with hopes hanging on Covid-19 vaccines, the WHO and experts are warning those same phenomena may jeopardise roll-out of immunisation programmes meant to bring an end to the suffering.

“The coronavirus disease is the first pandemic in history in which technology and social media are being used on a massive scale to keep people safe, informed, productive and connected,” the WHO said.

“At the same time, the technology we rely on to keep connected and informed is enabling and amplifying an infodemic that continues to undermine the global response and jeopardises measures to control the pandemic.”

More than 1.4 million people have died since the pandemic emerged in China late last year, but three developers are already applying for approval for their vaccines to be used as early as December.

Beyond logistics, though, governments must also contend with scepticism over vaccines developed with record speed at a time when social media has been both a tool for information and falsehood about the virus.

The WHO defined an infodemic as an overabundance of information, both online and offline, including “deliberate attempts to disseminate wrong information”.

Last month, a study from Cornell University in the United States found that US President Donald Trump has been the world’s biggest driver of Covid-19 misinformation during the pandemic.

In April, Trump mused on the possibility of using disinfectants inside the body to cure the virus and also promoted unproven treatments.

Since January, AFP has published more than 2,000 fact-checking articles dismantling false claims about the novel coronavirus.

“Without the appropriate trust and correct information, diagnostic tests go unused, immunisation campaigns (or campaigns to promote effective vaccines) will not meet their targets, and the virus will continue to thrive,” the WHO said.

‘Unparalleled scale’

Three vaccine developers — Pfizer/BioNTech, Moderna and AstraZeneca/Oxford University are leading the pack — and some governments are already planning to start vaccinating their most vulnerable this year.

But with Facebook, Twitter, YouTube or WhatsApp acting as vectors for dubious facts and fake news, “disinformation has now reached an unapparelled scale,” said Sylvain Delouvee, a researcher in Social Psychology at Rennes-2 University.

Rory Smith of the anti-disinformation website, First Draft, agreed.

“From an information perspective, (the coronavirus crisis) has not only underlined the sheer scale of misinformation worldwide, but also the negative impact misinformation can have on trust in vaccines, institutions and scientific findings more broadly,” he said.

Rachel O’Brien, head of the WHO’s immunisation department, said the agency was worried false information propagated by the so-called “anti-vaxxer” movement could dissuade people from immunising themselves against coronavirus.

“We are very concerned about that and concerned that people get their info from credible sources, that they are aware that there is a lot information out there that is wrong, either intentionally wrong or unintentionally wrong,” she told AFP.

Vaccine hesitancy

Steven Wilson, a professor at Brandeis University and co-author of a study entitled “Social Media and Vaccine Hesitancy” published in the British Medical Journal last month, saw a link between online disinformation campaigns and a decline in vaccination.

“My fear regarding the impact of disinformation on social media in the context of Covid-19 is that it will increase the number of individuals who are hesitant about getting a vaccine, even if their fears have no scientific basis,” he said.

“Any vaccine is only as effective as our capacity to deploy it to a population.”

Among the more outlandish claims by conspiracy theorists, for example, is the idea that the novel coronavirus pandemic is a hoax or part of an elite plan, masterminded by the likes of Bill Gates, to control the population.

And vaccination programmes, those groups say, are a shield for implanting microscopic chips in people to monitor them.

Such notions can find fertile ground at a time when polls show that people in some countries, such as Sweden and France, are already sceptical about taking vaccines, especially when the treatments have been developed in record time with no long-term studies yet available on their efficacy and possible side-effects.

Growing mistrust

Last month, a poll by Ipsos suggested that only 54 percent of French people would immunise themselves against coronavirus, 10 percentage points lower than in the US, 22 points lower than in Canada and 33 points lower than in India.

In 15 countries, 73 percent of people said they were willing to be vaccinated against Covid-19, four percentage points lower than in an earlier poll in August.

But it is not just vaccines — more and more people express a growing mistrust of institutions, experts say.

“The common theme” among conspiracy theorists “is that our ‘elites’ are lying to us,” said Rennes-2 University’s Delouvee.

Disinformation is based on growing mistrust of all institutional authority, whether it be government or scientific.

“When people can’t easily access reliable information around vaccines and when mistrust in actors and institutions related to vaccines is high, misinformation narratives rush in to fill the vacuum,” the First Draft report said.

Survey reveals one-third of Singaporean youth struggle with severe mental health issues

A national study by the Institute of Mental Health reveals that 30.6% of Singaporean youth suffer from severe symptoms of depression, anxiety, or stress, driven by factors like excessive social media use, body image concerns, and cyberbullying. The findings emphasize the need for early intervention and targeted mental health strategies.

A significant portion of Singapore’s youth are experiencing severe mental health challenges, according to a comprehensive national survey conducted by the Institute of Mental Health (IMH).

The National Youth Mental Health Study (NYMHS), released on 19 September 2023, found that 30.6% of individuals aged 15 to 35 reported severe or extremely severe symptoms of depression, anxiety, or stress, with key risk factors including excessive social media use, body shape concerns, and experiences of cyberbullying.

The study, which surveyed 2,600 Singaporean citizens and permanent residents, highlights the growing mental health concerns among Singaporean youth and suggests the need for more targeted interventions and support systems.

Mental Health Issues Prevalent Among Youth

Anxiety was the most common mental health issue, with 27% of respondents reporting severe or extremely severe symptoms, followed by depression (14.9%) and stress (12.9%).

These findings underscore the high prevalence of mental health issues among young people, particularly in those aged 15 to 24, who were more likely to report severe symptoms compared to older participants.

According to the IMH, young people who were female, single, unemployed, or had lower levels of education or household income were more prone to severe mental health symptoms.

For example, youth with monthly household incomes below S$5,000 were more likely to experience severe anxiety​.

Key Risk Factors: Social Media, Body Image, and Cyberbullying

The study identified three major factors linked to severe mental health symptoms:

  1. Excessive Social Media Use: Around 27% of respondents reported using social media for more than three hours daily, which was associated with a significantly higher likelihood of severe mental health issues. Youth with excessive social media use were 1.5 to 1.6 times more likely to experience severe symptoms of depression, anxiety, or stress​.
  2. Body Shape Concerns: About 20.2% of youth had moderate to severe concerns about their body image. These individuals were 4.9 times more likely to experience severe depression, 4.3 times more likely to experience severe anxiety, and 4.5 times more likely to suffer from severe stress​. Such concerns were often linked to social media exposure, which can perpetuate unrealistic beauty standards and increase dissatisfaction with one’s body.
  3. Cyberbullying: One in five youth (21%) reported being victims of cyberbullying. These individuals were approximately twice as likely to report severe mental health symptoms compared to those who had not experienced such harassment​. The anonymity and pervasive nature of online bullying exacerbates the mental health toll on young people, according to the study.

Demographics at Higher Risk

The study found that specific demographics were more vulnerable to mental health issues. Young people aged 15 to 24 were more likely to experience anxiety, depression, and stress, particularly females, those who were single, and those with lower levels of education, such as junior college or vocational qualifications​.

The Malay ethnic group was also found to have a higher prevalence of severe mental health symptoms compared to other ethnic groups​.

Barriers to Seeking Help and Sources of Support

Although about 69.1% of those with severe mental health symptoms sought help—primarily from family and friends—a significant portion of young people hesitated to seek professional support.

The top reasons included concerns about privacy, fear of judgment, and doubts about the effectiveness of professional services​.

Among those who sought help, family and friends were the most common sources of support (57.9%), followed by self-help measures (31.1%) and medical services (20.1%)​.

However, the reluctance to seek professional help highlights the need for continued efforts to destigmatize mental health treatment and increase awareness of available services.

Protective Factors: Resilience, Social Support, and Self-Esteem

The study also identified factors that helped mitigate mental health challenges. Youth who reported higher levels of resilience, perceived social support, and self-esteem were significantly less likely to experience severe symptoms of depression, anxiety, or stress.

This suggests that fostering strong support networks and building resilience in youth could play a critical role in improving their mental well-being​.

Government Response and Preventive Measures

The findings of the NYMHS support Singapore’s broader National Mental Health and Well-Being Strategy, launched in October 2023, which adopts a whole-of-government and whole-of-society approach to addressing mental health concerns. Schools have already begun integrating mental health education into their curricula, equipping students with the knowledge and skills to manage their well-being.

Additionally, the government introduced the Parenting for Wellness toolbox in September 2023 to help parents manage their children’s screen time and promote healthy social media usage.

A guide on responsible social media use, expected to be released by mid-2025, will offer further strategies to mitigate the negative impacts of excessive screen time and online harassment​.

Future Implications and Policy Development

Associate Professor Swapna Verma, chairman of IMH’s medical board and co-principal investigator of the study, emphasized the importance of early intervention.

“Not all individuals with severe or extremely severe symptoms of depression or anxiety have a clinical condition, but being in such states for a prolonged period of time can be detrimental to their well-being,” she said​.

The study’s data will help policymakers and healthcare providers develop more targeted approaches to address the mental health needs of Singapore’s youth, especially those most at risk.

Associate Professor Mythily Subramaniam, IMH’s assistant chairman of medical board (research), stressed the need to pay attention to issues like excessive social media use and cyberbullying, noting their “tremendous impact on youth mental health” and the importance of preventive measures​.

Support for Youth Facing Mental Health Challenges

Young people dealing with mental health challenges in Singapore have access to various resources:

  • CHAT (Centre of Excellence for Youth Mental Health): CHAT offers a safe and confidential space for youth to seek help through online and face-to-face mental health assessments and support.
  • Institute of Mental Health (IMH): IMH provides a comprehensive range of mental health services, including outpatient consultations and inpatient care. Youth in crisis can also seek immediate assistance from the 24-hour Mental Health Helpline at 6389 2222.
  • Samaritans of Singapore (SOS): SOS offers emotional support for those feeling distressed or experiencing suicidal thoughts. Their 24-hour hotline is 1767.
  • Health Promotion Board’s National Care Hotline: This hotline provides immediate emotional support for those in need and can be reached at 1800-202-6868.
  • Counselling Services: School-based counsellors, as well as community-based services such as TOUCH Youth, provide further avenues of support for young people grappling with mental health issues.

MALAYSIA: The Malaysian Health Ministry confirmed a new case of monkeypox (mpox) in a male citizen, marking the country’s first confirmed case of 2024.

The patient, who began showing symptoms on 11 September, is currently in isolation and in stable condition.

The ministry, in a statement issued Tuesday (17 September), revealed that the patient first experienced fever, sore throat, and cough, followed by the appearance of rashes on 12 September.

He has no recent history of international travel within the past 21 days, and authorities are in the process of identifying and monitoring his close contacts, following strict standard operating procedures (SOPs).

“Out of the 58 suspected mpox cases referred to the ministry this year, one case has been confirmed positive for mpox clade II as of 16 September,” the ministry stated.

“All 10 cases reported in Malaysia since July 2023 have been from clade II.”

The Health Ministry had earlier reported that Malaysia recorded a total of nine mpox cases since the first detection on 26 July 2023, with the most recent case reported in November 2023.

All previous cases had links to high-risk activities, but no deaths were reported.

Global Context and National Preparedness

Mpox was declared a Public Health Emergency of International Concern (PHEIC) for the second time on 14 August this year, due to the rapid spread of the clade Ib variant, particularly from the Democratic Republic of Congo (DRC) and neighboring African nations.

In response, Malaysia’s Health Ministry activated its national crisis response centre on 16 August to enhance readiness and coordinate preventive measures.

The ministry advised the public to take precautions, including maintaining personal hygiene and avoiding direct contact with individuals suspected or confirmed to be infected with mpox.

High-risk individuals experiencing symptoms such as fever, swollen lymph nodes, and rashes are urged to seek immediate medical attention.

Mpox is caused by the monkeypox virus (MPVX) and spreads through close contact with symptomatic individuals.

The incubation period is typically between 5 and 21 days, and patients remain contagious until all lesions have dried up and fallen off.
