The use of environmental variables to predict cholera hazard
Vibrio cholerae(V. cholerae) is a component of coastal and estuarine microbial ecosystems, with the copepod species of zooplankton that comprise the aquatic fauna of rivers, bays, estuaries and the open ocean serving as host for the bacterium. There is a remarkably strong association between cholera and some regional environmental factors such as the sea and climate. In this paper, the sea surface temperature (SST), sea surface height (SSH) and ocean chlorophyll concentration (OCC) of the nearest coastal environment derived from satellite remote sensing data are employed to predict the cholera hazard in coastal regions of eastern China, and the association between monthly cholera cases and in the study and the lag effects of the three oceanic environmental factors to the local cholera magnitude are analyzed.
