This episode of the "This Week in Virology" podcast features an interview with Peter Daszak, President of EcoHealth Alliance, recorded at the Nipah Virus International Conference. Daszak explains the mission and operational model of his organization, a non-profit that integrates high-level scientific research with on-the-ground, practical applications to address emerging infectious diseases. The discussion covers the "One Health" approach, which links human, animal, and environmental health to predict and prevent pandemics. Daszak details the Alliance's global strategy, which involves building local scientific capacity in partner countries rather than simply extracting samples. Key projects discussed include bio-surveillance for SARS-like coronaviruses in bats in China, studying the drivers of Rift Valley Fever in Africa, and using economic data on disease costs to influence policy on deforestation and the wildlife trade. A major finding from their work is the discovery of over 100 novel SARS-related coronaviruses, some capable of infecting human cells, highlighting the ongoing risk of spillover events.
Inside EcoHealth Alliance: A Mission to Predict and Prevent Pandemics
0:00:53 - A Unique Non-Profit Model: Peter Daszak explains that EcoHealth Alliance is a non-profit that combines academic-level scientific research with practical, on-the-ground charity work, aiming to apply scientific findings directly to solve real-world health problems.
02:51 - A Path to Virology: Daszak recounts his career journey, starting as a zoologist and parasitologist, and how volunteering at the CDC during the first Nipah virus outbreak in 1999 set him on the path of studying emerging diseases.
07:02 - A Global, Interdisciplinary Structure: The Alliance has a central office in New York but collaborates with and builds laboratory capacity in approximately 30 countries. Their problem-solving approach brings together experts from diverse fields, including economics, mathematics, and microbiology.
08:55 - How the Work is Funded: While the Alliance is a charity that accepts public donations, over 80% of its funding comes from competitive federal grants, similar to an academic research lab.
13:07 - Building Local Capacity: A core principle of the Alliance is to build sustainable scientific capabilities within the countries where they work. The goal is to train local scientists and establish infrastructure that will remain long after a specific project ends.
15:46 - Tackling Rift Valley Fever: In Africa, the organization takes a holistic "One Health" approach to Rift Valley fever by sampling wildlife, livestock, and people to understand the virus's complete lifecycle. This research helps create better predictive models to inform farmers about when to vaccinate their herds.
25:40 - Using Economics to Fight Deforestation: Daszak explains how land-use change, like deforestation, is a major driver of disease emergence. The Alliance calculates the economic cost of new diseases that arise from these activities (e.g., malaria) to show governments that deforestation can result in a net financial loss, thereby discouraging it.
27:39 - Uncovering a "Clear and Present Danger": The Alliance's work on the wildlife trade led to the discovery of over 100 new SARS-related coronaviruses in bats in Southern China. Some of these viruses can infect human cells in the lab and are not treatable with current therapies, highlighting an ongoing pandemic risk.
31:32 - How Success is Measured: Beyond scientific publications, success is measured by tangible outcomes, such as training local scientists, influencing government policies to reduce disease risk, and achieving changes in international health regulations.
33:08 - Settling the Debate: Do Bats Carry More Viruses? Daszak confirms that extensive analysis by his group, correcting for research biases, has proven that bats do harbor a significantly greater diversity of viruses per species compared to other mammals.
