Investigating the Zoonotic Interface in Post-Ebola Sierra Leone

Conducted by Catherine Bolten and primatologist Andrew Halloran, director of chimpanzee care at Save the Chimps, on the Tonkolili Chimpanzee Project. This project studies chimpanzee survival, conservation, and the possibilities for zoonotic disease transfer in light of rural food insecurity, overpopulation, climate change, and the recent Ebola epidemic.

Research Focus

  • Epidemiology

    At the EIGH, our researchers use epidemiology to understand the distribution and determinants of the health and disease conditions in specific populations, and to identify risk factors for certain diseases. This allows them to develop, implement, and measure the impact of targeted, preventative healthcare methods. 

  • Infectious Diseases

    At the EIGH, our researchers work to combat a number of various illnesses, including infectious diseases caused by organisms like bacteria, viruses, fungi, and parasites. These diseases can also be spread from one person to another and may be transmitted from animals to humans.
