- Summary Table: Public Health Challenges and Responses
Five years ago,on March 11,2020,the World Health Association (WHO) declared COVID-19 a global pandemic. The novel coronavirus, dubbed SARS-CoV-2
, emerged from Wuhan, China, in December 2019, initially reported as a cluster of severe pneumonia cases of unknown cause
. By March 11, it had spread to 114 countries, infecting 118,000 people.
Dr. Tedros Adhanom Ghebreyesus, then WHO director-general, expressed deep concern over the alarming levels of spread and severity and by the alarming levels of inaction.
He urged leaders to scale up their emergency responses
, emphasizing that all countries can still change the course of this pandemic.
During the pandemic, public health agencies such as the WHO and the U.S. Centers for Disease Control and Prevention (CDC) played crucial roles. They coordinated with local health departments to detect, trace, and test for the virus. Their websites became primary sources for up-to-date details on prevention, case numbers, hospitalizations, and deaths. The National Institutes of Health (NIH) was also instrumental in developing COVID-19 treatments and contributing to vaccine research.
However, five years later, significant changes have occurred.The Trump management has cut more than 5,000 employees at the NIH and the CDC combined, and is withdrawing the U.S. from the WHO.
Concurrently, the U.S.faces outbreaks of tuberculosis, a resurgence of measles among unvaccinated communities, and the worst flu season in 15 years.
The work of the WHO, CDC, and other public health agencies frequently enough goes unnoticed. Understanding public health before these organizations existed highlights their importance.
A Spreading Epidemic,Slow Communications
Before the establishment of international and national public health networks in the 1940s,coordinated communication,external investigations,and formalized data recording were absent. The lack of information sharing hindered the ability to link outbreaks and epidemics across regions.
The 1918 influenza pandemic exemplifies this. The deadly combination of influenza and pneumonia emerged from a Kansas army base in the spring of 1918. It spread to Asia and Europe by late summer and was mislabeled the “Spanish flu” upon its return to the U.S. in August. The initial lack of media coverage and disease tracking led many to believe the lethal strains originated in Europe.
Formal tracking began onyl when the disease returned with American troops in August 1918. In September, the U.S. Surgeon General and the U.S.Public Health Service attempted to gauge the magnitude and transmission of influenza by sending telegrams to state health officers.

By then, mass preparation was too late. Early reports were overshadowed by World War I news. People were largely unaware of the disease until it directly impacted their communities. Shortages of resources and caregivers forced communities to create makeshift hospitals and rely on healthy residents to care for the sick.
For instance, at the University of Kansas during the 1918 influenza pandemic, female professors cared for sick students, faculty and staff, washed linens, and prepared food. The absence of agencies like the WHO and CDC, compounded by wartime communication barriers, limited the sharing of crucial information across regions, including prevention strategies.

While public opinions of the CDC and the WHO shifted throughout the COVID-19 pandemic, recent survey results indicate that the majority of Americans trust public health agencies at least to some degree. A 2024 survey found that nearly 60% of american adults believe that the U.S. benefited from its WHO membership.
Sadly,when infectious diseases move out of the spotlight and are seen as less urgent,the critical roles of these public health agencies fade into the distant collective memory, much like the 1918 and COVID-19 pandemics. People soon enough forget the need for ongoing scientific research, educational programs and teams that can quickly respond to local, national and international levels.
Disease continues to be a threat, as the outbreaks of measles, tuberculosis, influenza and other pathogens remind us.People are still sick or dying of COVID-19: As of March 1, 6,725 people had died in the U.S. from COVID-19 just in 2025, and nearly 7.1 million have died worldwide as January 2020.
Without strong, coordinated efforts between public health agencies, even small health calamities can escalate into full-blown epidemics or even pandemics, which the world will be far less prepared to handle.
The Vital Role of Public Health Agencies: Q&A on Lessons from COVID-19 and Beyond
This article explores the critical functions of organizations like the WHO, CDC, and NIH, especially in light of the COVID-19 pandemic and historical outbreaks. Learn about thier vital role in public health and the consequences of their weakening.
1.Why was March 11, 2020, a significant date in recent history?
On March 11, 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic. By this date,the novel coronavirus had spread to 114 countries and infected 118,000 people worldwide.
2. What specific roles did public health agencies play during the COVID-19 pandemic?
During the COVID-19 pandemic, public health agencies such as the WHO and the CDC played crucial roles, including:
Coordinating with local health departments
Detecting, tracing, and testing for the virus
providing up-to-date data on prevention
Reporting case numbers, hospitalizations, and deaths
Developing treatments and contributing to vaccine research (NIH)
3. What changes have public health agencies like the CDC and NIH faced recently?
In recent years, the NIH and CDC have experienced significant changes, including:
Staff reductions: The Trump governance cut more than 5,000 employees from the NIH and CDC combined.
Withdrawal from WHO: The U.S. initiated withdrawal from the World Health Organization (WHO).
4. What concurrent public health issues are the U.S. currently facing?
Alongside changes in public health agencies, the U.S. faces several public health challenges:
outbreaks of tuberculosis
Resurgence of measles,particularly among unvaccinated communities
A severe flu season
5. Why is understanding public health before the existence of organizations like WHO and CDC significant?
Understanding the state of public health before the establishment of international and national public health networks in the 1940s highlights the critical importance of these organizations. This understanding showcases:
The critical importance of coordinated interaction
The value of external investigations
The necessity of formalized data recording in managing public health crises.
6. How did the 1918 influenza pandemic illustrate the challenges of public health before modern agencies?
The 1918 influenza pandemic exemplifies the public health challenges before entities such as the WHO and CDC:
Lack of coordinated communication
Absence of external investigations
lack of formalized data recordings
Delayed tracking and reporting: Formal tracking only began when the disease returned with American troops in August 1918.
7. What were some of the consequences of the lack of coordinated response during the 1918 flu pandemic?
The consequences of the delayed and uncoordinated response during the 1918 influenza pandemic included:
Widespread unawareness of the disease
Shortages of resources and caregivers
Reliance on makeshift hospitals and community volunteers.
Limited sharing of crucial information and prevention strategies.
8. How did the public perception of the CDC and WHO shift during the COVID-19 pandemic?
During the COVID-19 pandemic, public opinions of the CDC and WHO shifted. Though, recent surveys indicate that the majority of Americans still trust public health agencies to some degree and believe the U.S. benefited from its WHO membership.
9. What is the risk of neglecting public health agencies when infectious diseases are less prominent?
When infectious diseases are seen as less urgent, the critical roles of public health agencies can be forgotten. This can lead to:
A decline in ongoing scientific research
A reduction in educational programs,
Weakening of teams that can quickly respond to health threats.
10. What recent data highlights the continued threat of infectious diseases?
Recent data underscores the ongoing threat of infectious diseases. For example, in 2025 alone, 6,725 people died in the U.S. from COVID-19, and nearly 7.1 million have died worldwide since January 2020.
11. What could happen if coordinated efforts between public health agencies are weakened?
Without strong, coordinated efforts between public health agencies, even small health calamities can escalate into full-blown epidemics or pandemics, for which the world will be far less prepared.
12. What key lessons about public health can be learned from the COVID-19 pandemic?
The COVID-19 pandemic highlighted both the importance of public health agencies and the consequences of neglecting them.Key lessons include:
The need for coordinated international and national responses
The critical role of timely and accurate communication
* The importance of ongoing investment in public health infrastructure.
