Inside WHO’s Emergency Operations: How the World Detects and Responds to Health Threats
In the heart of Geneva, at the world Health Association’s (WHO) headquarters, lies the nerve center of global health surveillance—the emergencies operations center. Here, over 100,000 signals are received every month, each potentially signaling a health threat, outbreak, or even the next pandemic. But how does WHO sift through this avalanche of data to identify real threats? Dr. Chikwe Ihekweazu,a leading expert in global health security,sheds light on this critical process.
The Nature of Health Threats

“All around the world, something is happening,” explains Dr. Ihekweazu.From floods and heatwaves to conflicts and disease outbreaks, the world is constantly grappling with health challenges. Some threats are obvious, like natural disasters, while others are more insidious—such as clusters of illnesses caused by viruses or bacteria. “Our work is to have a system were we can find these and ensure humanity has a way of responding,” he adds.
These signals can take many forms. They might manifest as an unusual spike in hospital admissions, unexpected diseases affecting specific demographics, or even reports of increased mortality in certain regions. “Sometimes it’s very obvious—there’s a flood, war, or conflict—and people are dying,” says Dr.Ihekweazu. The key is distinguishing between what’s usual and what’s unusual,a task that requires global collaboration and advanced technology.
The Process of Detection and Verification
WHO’s system for detecting health threats is both automated and human-driven. “A lot of the early work is automated,” explains Dr. Ihekweazu. the system scans media sources, including newspapers, radio, and social media, and even receives direct reports from doctors in clinics worldwide. artificial intelligence (AI) plays a crucial role in filtering out the noise, but the final step—verification—relies on human expertise.
“Verification often means picking up the phone and calling a colleague in the community to ask, ‘What’s going on?’” says dr.Ihekweazu. In some cases, samples are collected and sent to labs to confirm the presence of a disease. This meticulous process ensures that resources are directed toward threats that require an organized response, while local hospitals handle more routine cases.
The Role of Countries and Collaboration
No country or community can tackle health threats alone. “Things can only be more than expected if you know what to expect,” emphasizes Dr. Ihekweazu. This requires global collaboration, not just between countries but across sectors—human health, animal health, and environmental monitoring. “If these three parts of our response aren’t working together, we don’t get it right,” he adds.
This collaborative approach is echoed in recent efforts by the Pan American health Organization (PAHO), which has approved a strategy to strengthen epidemiological intelligence in the Americas [[1]].Similarly, the Centers for Disease Control and Prevention (CDC) emphasizes the importance of resilient public health systems to prevent, detect, and respond to infectious disease threats [[2]].
How Individuals Can Help
Every individual has a role to play in this global effort. “Think of yourselves as health detectives,” urges Dr. Ihekweazu. Whether you’re a teacher, doctor, or community leader, reporting unusual health patterns in your area can make a difference. “If you see something unusual—children getting ill, more people dying, or even changes in weather affecting health—inform your local health authority,” he advises.
This grassroots vigilance is crucial for early detection.As Dr. Ihekweazu puts it, “Make sure someone knows about it, so they can pass the information to WHO.”
Key Takeaways: The Global Health Surveillance Process
| Step | Description |
|————————-|———————————————————————————|
| Signal Detection | Automated systems scan media, social platforms, and direct reports for anomalies.|
| AI Filtering | Artificial intelligence sieves out irrelevant data to focus on potential threats.|
| Verification | Human experts verify signals through direct communication and lab testing. |
| Collaboration | Countries and sectors work together to define and respond to unusual events.|
| Individual Role | Citizens act as health detectives, reporting unusual patterns to local authorities.|
A Call to Action
The fight against global health threats is a shared responsibility. By staying vigilant and reporting unusual health patterns, individuals can contribute to a safer, healthier world. As Dr. Ihekweazu reminds us, “We are all part of this global effort.”
So, the next time you notice something unusual in your community, remember: you could be the disease detective who helps prevent the next outbreak. Stay safe, stay healthy, and stick with science.
Inside WHO’s emergency Operations: A Conversation with dr. Chikwe Ihekweazu on Global Health Surveillance
In the heart of Geneva, at the World Health Organization’s (WHO) headquarters, lies the nerve center of global health surveillance—the Emergencies operations Center. Here, over 100,000 signals are received every month, each potentially signaling a health threat, outbreak, or even the next pandemic. But how does WHO sift through this avalanche of data to identify real threats? Senior Editor of world-today-news.com,Sarah Thompson,sits down with Dr. Chikwe Ihekweazu, a leading expert in global health security, to discuss the intricate process of detecting and responding to health threats worldwide.
The Nature of Health Threats
Sarah Thompson: Dr. Ihekweazu, thank you for joining us today. To start, could you give us an overview of the kinds of health threats WHO monitors on a daily basis?
Dr. Chikwe Ihekweazu: Absolutely, Sarah. Health threats come in many forms—some are obvious, like natural disasters such as floods or heatwaves, while others are more subtle, like clusters of illnesses caused by viruses or bacteria. Our work is to ensure we have a system in place to detect these threats early and respond effectively. Weather it’s an unusual spike in hospital admissions or reports of increased mortality in certain regions, we need to distinguish between what’s usual and what’s unusual. This is were global collaboration and advanced technology come into play.
The Process of Detection and Verification
Sarah Thompson: That’s captivating. Could you walk us through how WHO detects and verifies these threats?
dr. Chikwe Ihekweazu: Certainly. The process begins with automated systems that scan media sources, including newspapers, radio, and social media.We also receive direct reports from doctors and clinics worldwide. Artificial intelligence plays a crucial role in filtering out irrelevant data, but the final step—verification—relies on human expertise.Often, this means picking up the phone and calling a colleague in the community to ask, “What’s going on?” In some cases, samples are collected and sent to labs to confirm the presence of a disease.This meticulous process ensures that resources are directed toward threats that require an organized response, while local hospitals handle more routine cases.
The Role of countries and Collaboration
