Ebola is one of the deadliest viruses known to mankind. If left untreated, it kills about half of those it infects. The virus can spread through almost every fluid the body produces, including blood and sweat. Even the deceased can transmit the disease, often doing so at their own funerals.
On December 26th, 2013, a two-year-old boy in southern Guinea fell ill and died just two days later. It took local doctors, in collaboration with the international community, four months to discover that Ebola was to blame. This was largely because it had never before been detected outside of Central Africa. In those four months, Ebola gained a head start that would prove devastating. The outbreak lasted two years and became the largest Ebola epidemic in recorded history. More than 28,000 people contracted the disease and over 11,000 died.
In 2013, Guinea had no formal emergency response system, few trained contact tracers, and no rapid tests, border screenings, or licensed vaccine for Ebola. After that epidemic, Guinea, with the support of the US and other international partners, completely overhauled their epidemic response system.
In January 2021, the revamped system faced its first real test when a nurse in southern Guinea developed a headache, vomiting, and fever. A few days later, she died. As dictated by traditional burial practices, her family prepared her body for the funeral. Within a week, the nurse’s husband and other family members started experiencing symptoms. Health officials suspected Ebola much quicker than in 2013 and ordered tests. They came back positive, and Guinea activated its epidemic alert system the next day.
Guinea’s National Agency for Health Security activated 38 district-level emergency operations centers, as well as a national one. Teams of epidemiologists and contact tracers began the painstaking job of figuring out exactly who was exposed and when, generating a list of 23 initial contacts that quickly grew to over 1,100. Advanced rapid testing capacity spun up in the city where the outbreak started. At Guinea’s borders with Liberia and Cote d’Ivoire, public health workers screened more than 2 million travelers. A large-scale vaccination campaign was started. More than 900 community mobilizers alerted people of the outbreak and suggested alternative burial practices that were acceptable to the community and reduced the risk of spreading Ebola.
Thanks to all these measures, the 2021 outbreak ended just four months after it began. Only 23 people contracted Ebola; only 12 died. That’s less than 1% of the deaths in the prior outbreak. The 2021 outbreak cost $100 million to control—which sounds like a lot but pales in comparison to the global economic cost of the previous outbreak: $53 billion.
Should every country just copy Guinea’s approach? Not exactly. It is always important to respond to an outbreak quickly, so an early warning system is essential. But beyond that, a successful response can look very different for different diseases in different countries. For example, Brazil quenched an outbreak of yellow fever, which is spread by mosquitoes, primarily by mounting a massive vaccination campaign. That strategy worked well for Brazil because it’s one of the major global producers of the yellow fever vaccine, and its population was accustomed to regular, routine vaccinations.
But for many diseases, you don’t even need a mass vaccination program. In August of 2021, a truck driver tested positive for cholera in Burkina Faso. Health care workers alerted the government that same day and contact tracing began immediately. Cholera is caused by a bacterium, so Burkina Faso gave antibiotics to those exposed or potentially exposed. This extremely fast response stopped the outbreak just a few weeks after it started. Cholera often rears its head in West Africa—in 2021, there were over 100,000 cases and more than 3,700 deaths. Because Burkina Faso was so well prepared, they had zero deaths that year.
In Chiang Mai, Thailand, health officials piloted a community-owned, community-driven outbreak alert system to monitor animal health—that’s important because some animal outbreaks have the potential to spill over and become human outbreaks. Villagers used an app to alert health authorities about outbreaks in animals. Over the course of 16 months, 36 animal outbreaks were identified.
For any outbreak response system to be effective, it needs to be trusted, valued, and ultimately used by communities. That means reaching people where they are, in the language they speak, and aware of the culture, beliefs, and practices with which they live. Perhaps most importantly, we can’t expect to do nothing for years and then just swing into action when an outbreak occurs. One of the best ways to save lives is to invest in lasting health infrastructure, 365 days a year, for everyone, especially the most vulnerable among us.
Design an infographic that explains how Ebola spreads, its symptoms, and preventive measures. Use images, charts, and concise text to make it informative and visually appealing. Share your infographic with the class and discuss the key points.
In groups, simulate an emergency response to an Ebola outbreak. Assign roles such as epidemiologists, contact tracers, and public health officials. Develop a plan to identify, isolate, and treat patients, and present your strategy to the class. Discuss the challenges and solutions you encountered.
Research another major disease outbreak (e.g., COVID-19, SARS, or Zika virus). Compare and contrast the response strategies used in that outbreak with those used in the 2013 and 2021 Ebola outbreaks in Guinea. Create a presentation or report highlighting the similarities and differences.
Organize a debate on the topic: “Should every country adopt a standardized epidemic response system?” Divide the class into two teams, one supporting standardized systems and the other advocating for tailored approaches. Use examples from the article and your own research to support your arguments.
Imagine you are tasked with designing a community-driven outbreak alert system for your local area. Consider the cultural, social, and technological factors that would influence its effectiveness. Create a detailed plan and present it to the class, explaining how it would help prevent and control outbreaks.
