A prominent expert in viral diseases has cautioned that another global pandemic is not a question of “if,” but “when,” and that current preparations are insufficient to prevent widespread disruption. The warning comes as a continuation of a series spotlighting the impact of the Future Science Prize’s winners.
The Looming Threat of Respiratory Viruses
Malik Peiris, a distinguished Emeritus Professor at the University of Hong Kong, who played a crucial role in identifying the coronavirus responsible for the 2003 Severe Acute Respiratory Syndrome (SARS) outbreak, believes respiratory viruses pose the most significant pandemic risk. he emphasized that while numerous viruses have the potential to cause outbreaks, respiratory illnesses present the greatest danger of rapid, global transmission.
“it is absolutely certain that another pandemic will emerge,” Professor Peiris stated, adding that the Covid-19 pandemic starkly demonstrated the far-reaching consequences extending beyond public health to include significant economic and social instability.
The Need for a ‘One Health’ Approach
Professor Peiris argues that a more resilient approach to pandemic preparedness is paramount. This involves integrating the health of humans, animals, and the habitat-a concept known as “One Health.” He stresses that ignoring the interconnectedness of these factors leaves the world perpetually vulnerable to emerging infectious diseases. The World Health Association highlights the One Health approach as vital for optimal global health security.
Did You Know? Approximately 60% of known infectious diseases in humans are zoonotic, meaning they originate in animals.
Lessons from SARS-CoV-1 and COVID-19
While the 2003 SARS outbreak did not escalate into a full-blown global pandemic, Professor Peiris notes it served as a warning sign.The recent COVID-19 pandemic, however, demonstrated the speed and scale at which a novel virus could disrupt the world.
| Event | Year | Key Characteristics |
|---|---|---|
| SARS Outbreak | 2003 | novel coronavirus; High mortality rate; Contained relatively quickly. |
| COVID-19 Pandemic | 2020-Present | Novel coronavirus; High transmissibility; Global disruption. |
Pro Tip: Staying informed about public health recommendations and practicing good hygiene are essential steps in preparing for and mitigating the impact of potential pandemics.
Looking ahead: Strengthening Global Defenses
Professor Peiris’s warnings underscore the urgent need for increased investment in global health security, including enhanced surveillance systems, rapid response capabilities, and collaborative research efforts. A proactive, integrated approach, he insists, is the only way to minimize the impact of the inevitable next pandemic.
Pandemic Preparedness: A Long-Term Investment
The ongoing threat of pandemics necessitates a sustained commitment to preparedness. This includes not only scientific research but also addressing social and economic factors that contribute to vulnerability. Strengthening healthcare systems, improving access to vaccines, and promoting international cooperation are all crucial components of a complete strategy.
The past few decades have witnessed an alarming increase in emerging infectious diseases, linked to factors such as deforestation, climate change, and increased human-animal interaction. These trends highlight the need for a broader perspective on pandemic prevention that encompasses environmental sustainability and responsible land use practices.
Frequently Asked Questions About Pandemics
- What is a pandemic? A pandemic is an outbreak of a disease that spreads across a large region, typically multiple continents, affecting a substantial portion of the population.
- What is the ‘One Health’ approach to pandemic prevention? It’s an integrated approach that recognizes the interconnectedness of human, animal, and environmental health, acknowledging that addressing health challenges requires collaboration across disciplines.
- How did Professor Peiris contribute to our understanding of coronaviruses? He led the team that first identified the SARS-CoV-1 coronavirus responsible for the 2003 outbreak.
- What steps can individuals take to prepare for a pandemic? Staying informed, practicing good hygiene, and getting vaccinated are vital preventative measures.
- Is another global pandemic likely? Experts, including Professor Peiris, believe another pandemic is inevitable, emphasizing the need for ongoing preparedness efforts.

What specific measures does Dr. Ho suggest to strengthen global health security considering the increasing risk of zoonotic spillover events?
Top Hong Kong Virologist Warns: Next pandemic Inevitable, But World Unprepared
The Looming Threat of Pandemic 2.0
Dr. Ho Pak-Leung, a leading Hong Kong virologist renowned for his accurate predictions during the COVID-19 pandemic, has issued a stark warning: another global pandemic is not a matter of if, but when.His recent statements,delivered at the International Conference on Emerging Infectious Diseases in Hong Kong,highlight a critical lack of global preparedness despite the lessons learned from the recent coronavirus crisis. This assessment focuses on the increasing frequency of zoonotic spillover events and the evolving nature of viral threats, demanding immediate attention to pandemic preparedness, global health security, and infectious disease control.
Key Concerns Raised by Dr. Ho
dr.Ho’s concerns center around several interconnected factors:
Increased Zoonotic Spillover: the encroachment of human populations into wildlife habitats, coupled with climate change and intensified agricultural practices, is dramatically increasing the risk of viruses jumping from animals to humans.This is a primary driver of emerging infectious diseases.
Viral Evolution & Mutation: Viruses are constantly evolving. The potential for new, highly transmissible, and virulent strains to emerge is ever-present. The speed of viral mutation necessitates continuous surveillance and research.
Weakened Public Health Infrastructure: Many countries have scaled back investment in public health infrastructure since the peak of the COVID-19 pandemic, leaving them vulnerable to future outbreaks. This includes reduced funding for disease surveillance, laboratory capacity, and healthcare workforce.
Global Vaccine Inequality: Unequal access to vaccines and therapeutics remains a meaningful obstacle to global pandemic preparedness. Vaccine equity is crucial to prevent the emergence and spread of new variants.
Antimicrobial Resistance (AMR): The growing threat of AMR complicates the treatment of infectious diseases, potentially rendering existing medications ineffective. Antibiotic stewardship and the development of new antimicrobials are vital.
The Role of Novel Pathogens & “Disease X”
Dr. Ho specifically emphasized the potential for a “Disease X” – a hypothetical, unknown pathogen with the potential to cause a severe pandemic. The World Health association (WHO) includes Disease X on its list of priority pathogens needing research and countermeasure development. This highlights the need for:
Broad-Spectrum Antivirals: Developing antiviral drugs that are effective against a wide range of viruses, rather than targeting specific pathogens.
Rapid Diagnostic Tools: Investing in technologies that can quickly and accurately identify novel pathogens. Rapid diagnostics are essential for early detection and containment.
Platform Technologies: Utilizing platform technologies, such as mRNA vaccines, that can be quickly adapted to target new viruses.
Lessons from Past Pandemics: A Past Perspective
History is replete with examples of devastating pandemics. The 1918 Spanish Flu, the 2009 H1N1 swine flu pandemic, and, most recently, COVID-19, all demonstrate the profound impact infectious diseases can have on global health, economies, and societies.
Spanish Flu (1918-1920): Estimated to have infected 500 million people worldwide and resulted in 50-100 million deaths. Highlighted the importance of non-pharmaceutical interventions (NPIs) like mask-wearing and social distancing.
SARS (2003): Demonstrated the rapid global spread of novel coronaviruses and the need for robust quarantine measures.
MERS (2012): Showed the potential for zoonotic coronaviruses to cause severe respiratory illness.
COVID-19 (2020-Present): Exposed vulnerabilities in global supply chains, healthcare systems, and international cooperation. Accelerated the development of mRNA vaccine technology.
Strengthening Global Pandemic Preparedness: Actionable Steps
Addressing the looming pandemic threat requires a multi-faceted approach:
- Invest in Early warning Systems: Enhance global surveillance networks to detect emerging infectious diseases early on. This includes strengthening genomic surveillance capabilities.
- Boost Public Health Capacity: Increase funding for public health infrastructure, including laboratory capacity, healthcare workforce training, and disease surveillance programs.
- Promote International Collaboration: Foster greater cooperation between countries in sharing data, resources, and expertise. Strengthen the role of the WHO.
- develop Universal Vaccine Platforms: Invest in research and development of platform technologies that can be rapidly adapted to target new pathogens.
- Address vaccine Equity: Ensure equitable access to vaccines and therapeutics for all countries.
- Combat Antimicrobial Resistance: Implement robust antibiotic stewardship programs and invest in the development of new antimicrobials.
- One Health Approach: adopt a “One Health” approach that recognizes the interconnectedness of human, animal, and environmental health. This is crucial for preventing zoonotic spillover events.
- Improve Public Interaction: Establish clear and effective communication channels to inform the public about pandemic risks and preventative measures. Combat misinformation and promote health literacy.
The Economic Impact of Pandemic Preparedness
While investing in pandemic preparedness requires significant financial resources, the economic costs of not preparing are far greater.The COVID-19
