Dr. Dr Eric Bertherat is a specialist in public health and tropical medicine, graduated in tropical microbiology at Pasteur Institute. In the department of Infectious Hazard Management, WHO Geneva, he is the focal point for all preparedness and response activities related to plague, tularemia, anthrax, rickettsioses and other bacterial epidemic diseases of international importance. He also supports the WHO activities related to CBRN.
He has taken part in and led more than 15 responses to outbreaks of international importance.  including on cholera, viral haemorrhagic fevers, Nipah virus, meningitis and plague.
Dr Eric Bertherat joined WHO in 2001. Formerly he was a medical officer in the French Armed Forces and worked several years in developing and post-crisis countries at different levels of their health systems.
His areas of expertise include communicable disease epidemiology, outbreak preparedness and response, and biosecurity.

Presentation title: 'Biodiversity Loss and Emerging Infectious Diseases'

Dr. Christine K. Johnson is Professor of Epidemiology and Ecosystem Health and Director of the EpiCenter for Disease Dynamics in the School of Veterinary Medicine at the University of California, Davis. Her research activities focus on epidemiologic drivers of zoonotic disease spillover and spread and ecosystem level processes that impact wildlife population health and emerging infectious diseases. She provides epidemiologic support to federal and state agencies to address challenging environmental issues and has pioneered surveillance design and risk characterization for field studies on the local to global scale. Professor Johnson currently leads surveillance activities for USAID’s Emerging Pandemic Threats PREDICT project to identify infectious disease threats at high-risk animal-human interfaces and work with implementing partners and international organizations to meet global health priorities. At the University of California, Davis, her accomplishments include mentorship of post-doctoral scholars and graduate students interested in advanced training in disease dynamics, and the design of core didactic instruction in one health and ecosystem health for graduate and professional degree programs.

Peninah MUNYUA, Kenya
Presentation title: ''Rift Valley Fever in Kenya"

Peninah Munyua is an epidemiologist and One Health Program Director in CDC Kenya. Over the last 10 years, Dr. Munyua has conducted research to define the epidemiology and burden of infectious diseases, including zoonoses at the human-animal interface, to guide the development of control strategies in unique tropical settings. She has also been involved in implementation of global health security focusing on building capacity for public health systems including the establishment of infectious diseases surveillance systems, surveillance for animal diseases, contingency planning for emerging and re-emerging infectious diseases, building platforms for the One Health approach in Kenya, disease preparedness and control strategies for influenza, Rift Valley Fever, brucellosis, and rabies among other infectious diseases. She has a Bachelor's degree in Veterinary Medicine, Master's degree in Veterinary Epidemiology and Economics and a PHD in epidemiology from the University of Nairobi, Kenya.

Andre SIQUEIRA, Brazil
Presentation title: ''Yellow Fever in Brazil – Including Controversies around Fractionated Vaccination and Booster"


Andre Siqueira is an Infectious Diseases Consultant and Clinical Research Scientist at the National Institute of Infectious Diseases Evandro Chagas of Oswaldo Cruz Foundation. He is involved in research on acute febrile illness, including malaria treatment and control strategies and arboviral infections, with a focus on improving management of yellow fever and chikungunya fever natural history and treatment. He has participated of national and international expert panels and is a member of several technical advisory committees. 

Andy TATEM, Sweden
Presentation title: 'Using Mobile Data and Global Mapping to Tackle the Next Outbreak'

Andy Tatem is Professor of spatial demography and epidemiology at the University of Southampton and is the Director of WorldPop (, leading a group of more than 30 researchers and data scientists. He is interested in how populations, their characteristics and their dynamics can be mapped at high resolution across low and middle-income countries, with a particular focus on human mobility and spatial connectivity and how it impacts pathogen spread and elimination strategy design. His research has led to new approaches to the use and integration of satellite, survey, cell phone and census data to map the distributions and dynamics of vulnerable populations for disease, disaster and development applications. He runs international collaborations with national governments, UN agencies and data providers, and leads multiple research and operational projects funded by the Bill and Melinda Gates Foundation, Wellcome Trust, World Bank, Clinton Health Access Initiative and others.
