Public health has really not taken the best advantage of available big data, so this is one of the key ones being utilized at this point. There are other big data sets that could be examined, and the application of algorithms and artificial intelligence.

Internationally, I believe flight patterns and that type of information is going to be used and is being used, and other countries are using it to look at the spread of infectious disease. However, there are other applications in terms of healthy living and climate change and other big data sets that we could probably take more advantage of.
