What we must learn from Covid-19

Hardship, crisis, misfortune, and mistakes often provide the most valuable insights. The Covid-19 pandemic is a case in point. For all the suffering that the virus has caused, it has also highlighted the steps that countries must take, both collectively and individually, to prepare for future global public-health emergencies. Now, with the pandemic seemingly in the rearview mirror, the question is whether political leaders around the world will take its lessons to heart.

This is not a trivial question. Over the past few decades, disease outbreaks have triggered a recurring cycle of panic and neglect among policymakers. But in light of the human, economic, and social devastation wrought by Covid-19, we can and must break this pattern.

If Covid-19 has taught us anything, it is that factors such as climate change, human encroachment on wildlife habitats, population growth, urbanisation, and low-cost travel make it increasingly likely that we will face more devastating pandemics in the not-too-distant future. A 2021 study found that the “yearly probability” of extreme epidemics could “increase up to threefold” in the coming decades. It would be extremely reckless not to take decisive action now to mitigate this looming threat.

Another crucial lesson from Covid-19 is that all countries must have robust health systems capable of responding quickly and effectively to an emergency while simultaneously addressing ongoing health-care needs. Even well-resourced countries struggled to perform this complex balancing act during the pandemic, resulting in millions of deaths and severe economic damage.

Governments around the world owe it to their citizens to make significant and sustained investments in areas such as disease surveillance, outbreak-response capabilities, primary health-care services, and health-care worker training. Such investments are needed not only in wealthier countries but also in lower-income countries that cannot afford them on their own.

All of this underscores the imperative for wealthy countries to step in and provide critical assistance. Throughout the pandemic, these countries’ governments, recognizing that deadly pathogens are indifferent to national borders, repeated the mantra that “no one is safe until everyone is safe.” And yet, despite this lofty rhetoric, lower-income countries found themselves last in line for diagnostics, vaccines, treatments, and other crucial supplies. Gavi, the Vaccine Alliance (whose board I chair) had to wait months before the Covax facility it established in 2020 managed to overcome vaccine hoarding and export bans and start shipping significant quantities to the countries most in need.
