COVID-19’s Impact and Future Pandemic Preparedness
Since the onset of the pandemic, COVID-19 has taken over 7 million lives globally, with the United States accounting for more than a million of those deaths, as noted by the World Health Organization. Beyond the mortality figures, the virus has led to a surge in chronic health issues among survivors. At its height, it also caused significant disruptions in supply chains and health care systems, which greatly impacted society and even reduced global life expectancy.
The novel coronavirus, SARS-CoV-2, has significantly reshaped our world since it first appeared in 2019. Yet, experts warn that the next pandemic might be even more devastating.
This concern is articulated in a new book by Michael Osterholm, the founding director of the Center for Infectious Disease Research and Policy at the University of Minnesota, and co-author Mark Olshaker. The book, titled “The Big One: How We Must Prepare for Future Deadly Pandemics”, emphasizes the lessons learned from previous pandemics and outlines preventive actions that can be taken to reduce harm and save lives in the face of future outbreaks.
Interestingly, this book was completed before Donald Trump began his second presidential term. Osterholm pointed out to Live Science that the country’s pandemic response capabilities have been severely compromised. He mentioned that the White House’s office responsible for handling such matters has been disbanded.
In discussing his book with Live Science, Osterholm elaborated on what we might anticipate from the next pandemic and how we can get ready, both under favorable conditions and within the current challenging landscape in the U.S.
When asked about the phrase “The Big One,” Osterholm referred to his experience with coronaviruses, highlighting two critical features: infectiousness and lethality. He previously worked on the SARS and MERS viruses, which, although deadly, did not spread as easily. In contrast, COVID-19 proved to be highly contagious, albeit with a lower fatality rate than those earlier infections.
Recently, new coronaviruses have been isolated from bats in China that exhibit both high infectiousness and lethality. This combination raises concerns when thinking about potential future pandemics. Imagine if a virus as infectious as COVID-19 emerged but had a mortality rate comparable to the more severe coronaviruses—this scenario embodies the essence of “The Big One.”
Osterholm emphasized that significant influenza pandemics have not occurred since 1918, indicating that a similar or worse one could emerge in the future. He clarified that while COVID-19 was devastating, it pales in comparison to what could happen in a future pandemic.
In terms of transmission, Osterholm pointed out the concept of “viruses with wings,” which aptly describes those that can travel widely and rapidly, increasing their pandemic potential. He argued that the most likely candidates for the next pandemic will be influenza or coronaviruses, since those are known for respiratory transmission. However, any surprise pathogen would also need those specific traits to qualify as a pandemic threat.
Osterholm discussed the importance of airborne transmission in making a virus capable of widespread infection. He reflected on how COVID-19 had asymptomatic individuals spreading the virus, a characteristic not seen as prominently in past outbreaks like SARS and MERS.
When it comes to addressing a pandemic, Osterholm is clear: while it’s difficult to prevent a pathogen from spreading, we can mitigate its effects. He pointed out a thought experiment in the book that illustrates how rapidly a virus could spread globally, emphasizing the need for readiness.
Osterholm criticized the disbanding of vital pandemic preparedness programs in the U.S. and expressed concern about the nation’s ability to produce vaccines quickly enough in a crisis. The reliance on traditional production methods limits the speed and volume of vaccine availability, which poses a serious threat in a pandemic scenario.
Despite advancements like mRNA technology, funding cuts have hindered critical developments, leaving the country vulnerable. He argued that this is akin to losing essential resources at a critical moment.
Osterholm discussed the advantages of mRNA technology, particularly its speed and versatility in vaccine production. He emphasized that this method allows for quicker responses to emerging threats, providing hope for addressing future pandemics.
Effective communication during a pandemic is another central theme of the book. Osterholm believes that transparency in scientific understanding is crucial, noting that science is a journey toward truth, not an absolute. The pandemic response should include clear information about hospital capacities and realistic expectations about public health measures, rather than oversimplifying the challenges. He criticized the national response for treating the pandemic as a short-term crisis rather than a prolonged struggle.
Finally, when it comes to public involvement in pandemic readiness, Osterholm emphasized the importance of citizen engagement. He encouraged individuals to connect with local health organizations and stay informed about legislative actions related to public health.
Osterholm’s perspectives urge us to reflect on our preparedness for future pandemics, illustrating both the challenges we face and the steps we can take to improve our responses.
