Early warning system for epidemics: Risk map correlates environmental, health data

Posted by External 60 days ago General
http://feeds.sciencedaily.com — The environment has an impact on our health. Preventing epidemics relies on activating the right counter-measures, and scientists are now trying to find out how better use of forecasting can help. The EU’s EO2HEAVEN project developed a risk map for correlating environmental and health data in order to identify where a disease may break out next. Read More
