Dr. Eric Osoro is a Medical Epidemiologist and Deputy Country Director of the WSU Global Health Program - Kenya. Dr. Osoro obtained his Bachelor’s degree in Medicine and Surgery from Moi University, Kenya in 2004. Following graduation he joined the public health service practicing in district hospitals in different parts of the country. He joined the Field Epidemiology and Laboratory Training Program (FELTP) where he obtained his Master’s Degree in Applied Epidemiology in 2010.  Dr. Osoro has also undertaken a fellowship on Emerging Pandemic Threats and One Health with the African Field Epidemiology Network (AFENET). In 2010, he was appointed a regional epidemiologist in Western Province of Kenya where his responsibilities included coordinating communicable diseases prevention and control activities. In 2012, Dr. Osoro joined the Zoonotic Disease Unit which is the coordinating one health office in the Government of Kenya. He was involved in novel initiatives bringing together animal and human health professions to address zoonotic diseases. These included development of guidelines for control of zoonoses including rabies and rift valley fever, participating in collaborative field research projects on brucellosis and influenza and conducting surveillance and outbreak investigations. In 2016, he joined WHO as part of the team which was responding to the Ebola outbreak in Sierra Leone before his current assignment. 

Personal Statement

My interest in public health was nurtured during several years of clinical practice in middle level hospitals in Kenya. I frequently had to attend to scores of people affected by a disease outbreak such as anthrax, manage children with preventable diseases, and trauma from road crash victims. When I was charged with the responsibility of monitoring quality of care in our unit, I began enquiring on how we could reduce the apparently preventable cases. I quickly realized there no systematic documentation and the observations were only known to us and desired to get the skills to address the need. I therefore decided to purse a career in epidemiology to contribute to generating the information needed to apply interventions to public health problems. Besides my professional duties position, I have a passion for reading and travelling.

General Research / Expertise

Dr. Osoro is an investigator in a number of research projects at the WSU Global Health Program - Kenya. He conducts field research at community and hospital level. His area of study is on emerging and zoonotic diseases such as Zika virus infection outcomes and burden of zoonotic diseases in Kenya. His research seeks to establish areas where the diseases occur frequently and reasons for such occurrence. This information is crucial to inform evidence-based interventions to reduce the burden of zoonotic diseases.

Research Contributions

Dr. Osoro’s main research contribution is the understanding the burden of zoonotic diseases such as brucellosis and rabies in Kenya. This includes investigating how the interlinkage between humans and animals affect the occurrence of these diseases. Our research on brucellosis documented the burden in different parts of the country contributing to formulation of targeted health interventions. He has also been involved in linking research and policy by collating research findings to develop of disease control guidelines.

Research Details

We highlight two areas of Dr. Osoro’s research:

  1. Conducting epidemiological research to estimate the burden of endemic and emerging zoonoses in Kenya. We have conducted collaborative field studies looking at the burden of priority zoonotic diseases including brucellosis and influenza. The studies involved sampling both humans and animals in the same households and determining factors associated with exposure or infection. Our study on brucellosis highlighted the differential distribution of brucellosis in the country -- which was different from what was routinely reported from public health data.

  2. Translating research into policy documents. Dr. Osoro has coordinated professionals from human and animal health to review available research on zoonotic diseases to develop appropriate control guidelines. This work has resulted in development of a priority zoonotic disease list for Kenya and control guidelines for rabies and Rift Valley fever.
