A team of scientists from the Johns Hopkins University Applied Physics Laboratory has developed a novel capability to predict the outbreak of infectious diseases. The new method, known as PRISM – Predicting Infectious Disease Scalable Model – extracts relationships among clinical, meteorological, climatic, and socio-political data.
Visit the PRISM web site for more information.

The July 2014 issue of the Johns Hopkins APL Technical Digest focuses on Global Health Surveillance, describing the development, implementation, and adaptation of the SAGES suite of tools; the process of the making the tools open source; and potential new analytic models for early detection of disease outbreak.
