STOP Spillover

About STOP Spillover

  • STOP Spillover is a global consortium funded by USAID and led by Tufts University that is working to understand and address the risks posed by known zoonotic viruses with the potential to spill over from animals and cause outbreaks, epidemics, and pandemics in humans.

  • We're working in countries at high risk for emergence and re-emergence of known zoonotic viruses with pandemic potential, and will work directly at suspected spillover locations – places where zoonotic viruses are likely to make the jump from animals to humans.

  • This five-year project will work in 10 countries, starting with four countries in the project’s first year, and will focus on a number of prioritized zoonotic viruses including Ebola, Marburg, Lassa, Nipah, animal-origin coronaviruses (including SARS, MERS-CoV, and SARS-CoV-2), and zoonotic influenza viruses.

  • STOP Spillover is pursuing a One Health approach, recognizing that the health of people is closely connected to the health of animals and our shared environment. Deforestation, climate change, population density, and other factors have put humans in closer and more frequent contact with wildlife, and put humans at greater risk for zoonotic viral spillovers.

  • STOP Spillover’s country teams will work with local, regional, and national government partners to develop and strengthen programs to limit the drivers of viral spillover from animals to humans and to address human behaviors that may increase risk.

  • SEAOHUN in collaboration with iccdr,b and its country networks manages the implementation of the STOP Spillover project in Asian countries. 

Cow and Calf

More than 70 percent of emerging and re-emerging infectious diseases originate from animals and some of those pathogens shared with humans can cause outbreaks, epidemics, and pandemics that may leave indelible marks on our societies like the global COVID-19 crisis. Through projects like STOP Spillover, we can strengthen country-level One Health capacity to address the drivers of spillover and advance global health security. The next pandemic and the next viral spillover from animals to humans aren’t inevitable – they can be prevented if we understand the risks and act.
