In the late winter and early spring of 2020, the coronavirus pandemic grew from a geographically limited viral infection into a full-blown national emergency, disrupting life as we knew it. The devastation was immense: mass mortality and widespread trauma. As the world ground to a halt, public health professionals mobilized, shifting into high gear to address the crisis.
Five years later, the numbers are staggering: Globally, more than 20 million lives have been lost. In the United States, the death toll has surpassed 1.2 million — greater than the fatalities from the Civil, World, and Vietnam wars combined.
Tragically, the pandemic’s impact persists, with at least 1,000 people dying from Covid each week, 75% of them in the U.S., according to the World Health Organization (WHO).
While the scars of illness and feelings of loss of control linger, this anniversary offers an opportunity for critical reflection: to take stock of what we learned, what worked, and how to better protect public health against future pandemics. One fact is certain: The nation’s front-line public-health workers — doctors, nurses, social workers, and staff up and down the hierarchy of our complex health delivery system — performed their jobs heroically to fight a novel virus, buying critical time until the first vaccines could be developed. The recent and heartbreaking measles outbreak in New Mexico and Texas underscore the continued need for ongoing surveillance and prevention (i.
e. vaccination) strategies. Indeed, lessons we take with us into the future include: A strong public health system is essential to fighting new threats.
In addition to combatting chronic disease, the public health system responds to crises stopping outbreaks before they start. The pandemic showed us how important it is to have systems that can quickly find and track new viruses as they spread. It ushered in a new era of genomic surveillance, allowing scientists to track the coronavirus’ evolution, informing public health strategies.
Diagnostic tests helped identify who was infected with the virus to track its spread in communities and guide treatment decisions. Contact tracers, in turn, disrupted transmission chains by notifying potentially exposed individuals and providing crucial guidance. Future pandemics may require rapid, mass testing.
This demands ample supplies, trained staff, and a stockpile of generic tests to avoid shortages. Before a Covid vaccine was available, public health leaders relied on everyday human actions to control the virus. These included masking, social distancing, travel restrictions, and school and business closures.
The interventions drew heated criticism from many people and are still a political flashpoint, but they undoubtedly saved hundreds of thousands of lives. Early on, experts turned to past outbreak data and new tech tools to quickly determine the best course of action. Because of Covid, scientists quickly created advanced computer models to predict how the virus would spread.
These models helped governments make smart choices by showing what might happen with different actions, like vaccinations or lockdowns. The Covid-19 vaccines are the fastest vaccines ever created. The rapid development, manufacturing, and distribution of safe, effective vaccines in record time — one year — is a remarkable achievement that prevented innumerable deaths.
But disparities persisted, with marginalized communities experiencing lower vaccination rates because they had no access to healthcare, transportation, or information. Creating new drugs and vaccines for the next pandemic will be expensive and take time. To prepare, we need to be on the lookout for existing drugs and vaccines that could be repurposed and stockpiled for future use.
This means having a system to identify potential candidates and make sure they are safe, effective and accessible. In a rapidly evolving pandemic, where evidence and guidance are constantly shifting, transparent and timely communication is paramount. Public trust erodes when the rationale behind decisions lacks transparency, hindering the acceptance of critical public health measures.
To maintain trust and combat misinformation, ongoing efforts are needed to engage communities, share verified information, and improve health literacy. This includes collaborating with stakeholders, actively publishing accurate information, and enhancing media literacy skills. Covid exposed deep health inequities, with vulnerable communities experiencing worse outcomes.
Often, communities of color, the elderly, and those with limited resources faced higher infection rates, more severe illness, and greater economic hardship. This highlights the urgent need for targeted interventions that address root causes. Hyperlocal engagement and community partnerships offer a powerful way to address these disparities.
By working directly with communities, we can create tailored solutions that promote health equity. Robust partnerships are essential, and, in a pandemic, the world is small. This necessitates collaborations with academia, industry, government agencies, and international bodies such as the World Health Organization, which played a key role in global response to the pandemic.
As a United Nations agency comprised of 194 member states including the U.S., the WHO provided guidance, disseminated epidemiological updates, and established international agreements necessary for a coordinated global effort.
