That list was never meant to be inclusive, but rather to be a good introduction to current thoughts/issues in disease surveillance. If you have any suggestions to add other tools or websites, please contact us.

The WHO in collaboration with the US CDC has developed numerous field training programs in epidemiology.  As part of this effort, the WHO has created a virtual resource center which contains lectures, materials, and handouts to assist students in learning epidemiology and outbreak response. In the web site you'll find a section over biostatistics that would help teach/remind you of some of the important basic concepts, as well as more advanced analytical techniques. In addition, the section over outbreak investigations includes many examples and ideas that you could put into practice.
