Climate change and infectious diseases (Contd.)   Predictive Modeling (continued) Statistical models require, first, the derivation of a statistical (empirical) relationship between the current geographic distribution of the disease and the current location-specific climatic conditions. By then applying this statistical equation to future climate scenarios, the actual distribution of the… Read More

Epidemiology Week 26
