In response to this challenge, the EPHTN program was established to develop a comprehensive environmental public health surveillance system. EPHTN data are characteristic of much information currently being collected--they are multivariate, with many predictors and response variables, often aggregated over geographic regions (small and large) and correlated in space and/or time. Although an EPHTN would require ongoing, systematic data on a variety of environmental exposures, at present there are few examples of regulations or laws that require such information be collected. |
