Launched in 2006, SpatioEpi was initially a project by Stanley Ho Centre for Emerging Infectious Diseases in School of Public Health (now The Jockey Club School of Public Health and Primary Care) and students from the Department of Geography and Resource Management of The Chinese University of Hong Kong. The page SpatioEpi.com was set up in 2007 to promote the study of public health, environmental problems and disease transmission in geographical perspectives.
