How a $100 million grant aims to catch the next pandemic early
In short: When a feverish passenger landed in Lagos in 2014, the world was on the brink of an Ebola catastrophe. Now, a massive new infusion of capital is powering a high-tech surveillance network designed to ensure such a delay never happens again.
The Sentinel project, led by Pardis S/Sabeti and Christian Happi, is an early-warning system designed to detect and track viral threats in real time. Founded in 2020, the initiative works to help frontline health workers identify outbreaks before they escalate into global pandemics. Working alongside Nigeria's Institute of Genomics and Global Health, the Broad Institute co-operates this initiative, which maintains extensive ties throughout West Africa and Sierra Leone. The multidisciplinary team utilizes expertise in genomics, data science, and epidemiology to strengthen local health systems. Their mission is to empower communities to recognize unusual disease patterns and share critical information globally.
In November, the MacArthur Foundation awarded Sentinel the $100 million '100&Change' grant, selecting it from nearly 900 applicants. This funding will allow the team to expand its reach beyond its current footprint in 53 of Africa's 54 countries. Plans include integrating tools into the national public health systems of Nigeria and Sierra Leone, and formalizing work in nations like Rwanda, Senegal, and the Democratic Republic of the Congo. To grow the initiative, we are collaborating with the Nigeria Centre for Disease Control and Prevention to incorporate their training and data platforms into the country's infrastructure. They also aim to support a fully integrated model for outbreak response in Sierra Leone.
The impact of such surveillance is already measurable. During a 2024 Marburg virus disease outbreak in Rwanda, Sentinel's involvement helped contain the virus within 66 days. This resulted in a 20% case fatality rate—a significant reduction compared to the 40% to 90% fatality rates seen in all other recorded Marburg outbreaks. Moving forward, the team intends to adopt a 'One Health' framework, monitoring the links between human, animal, and environmental health to tackle zoonotic threats like avian influenza. This integrated surveillance approach is designed to address zoonotic threats, such as avian influenza, by recognizing that environmental and animal health are inextricably linked to human well-being.
